Im not a ar guy. But i need one pretty quick. My buddy who after a decade in the military moved back a few months ago. Hes a local cop and the sniper on our county swat team we are in a very rural area. he runs a dpms mini sass for his all around gun. We are going to be shooting alot this summer. We are building a hell of a range. Im gonna load 77grain sierras.

The mk12 platform seems kinda what im looking for. What are some good clones. Im looking at the daniel defense mk12 and the 18 inch v9. Also Pof r415 18inch. We are gonna have 1100 yards. But probably take these to 600. Were doing alot more than long range stuff. I have a $2k budget on the gun i already have a 2.5x10x42 nightforce so the scope is not on that budget. rifle only thanks to all

Hit up Kevin at high caliber sale. He can build you a true spec mk12 mod 1 upper built by the same guy who builds them for crane. Basic upper will cost $1500ish. Slap a lower on it and run it. Swfa has arms 22h rings in stock. Grab em and you'll have a spec build. That would fall in your 2k range.
 
#3
Obviously for MK12 clones either the Mod 0 or Mod 1, as mentioned already Kevin at HCS or Monte at Centurion rank very high with their to spec uppers to include conyract barrels, but they are pricey around $1700. PRI has a fairly decent MK12 rifle for around $1700, Steve at ADCO and Wes at MSTN also produce some very good products.
 
#4
Yep that was a option i was open to as well. Ive been meaning to get a ar going and i have parts. Ive just never fell in love with a ar-15. Bolt guns are my thing. Hell i have a 3mr tac con trigger thats been in my desk for 2 months. and i can get a usm4 3 pos lower that would be a wicked little set up. Any idea how long the wait is on these uppers. And what is limit i could push with it. Hand loading 75 amax and 90gr bergers single shot. Is 800 doable.
 
#5
Running a Mk12 Mod 0 clone with a contract barrel, accuracy is outstanding, Mk262 at 680 on 33% IPSC was great even in moderate winds. My own loads with tac or re15 and 77smks is slightly better. Single feeding 80 grain Sierras to 800 or further shouldn't be a problem, I personally don't think I would be interested in running 90's though.
 
#6
Another bump for Monte and Kevin, both are awesome guys who will take care of you. Kevin has SH deals, ask him about them, he hooked me up when I needed glass for my SPR knock off. Wes as MSTN was also a big help and is on here all the time, and helped with some good info. Any one of the three will leave you very, very happy.
 
#7
It's getting so that a true Mk12 (1 or 0) is a bit of a novelty. This is especially so when it comes to the rail, optics, mount, and for many...the muzzle device. The barrel is still very much relevant. I've talked with Kevin at HSC quite a few times recently, he is great to deal with. If you don't want a true MK12 clone, they can piece an upper together for you that will do just as well (or better). They did mine with a barrel I supplied from Monte/Centurion. All said and done, it cost me a few hundred less than what one of their MK12 uppers would have run.

Im very aware of the grendel and i agree. Im going with this 5.56 route because of my freind. So we can stay with the same ammo on the cheap shit we buy in bulk. Were gonna be shooting so much grendel would cost a bit more. We are building a shoot house and some other stuff that is close in on my range. Ive got .308 and 300 wins for anything 800 and out i was just asking if its doable. In the first post i said we will be mainly going to 600. But thats the real reason to stay 5.56 cost and to stay same cal.

hahahah. well i just bought one. at dealer cost so i wont lose any money when i sell. but that's my luck i bought a fiero. but with most guns im sure it will out shoot me. i don't have time for a custom build at the moment. anyway i can put it on gunbroker and make $300.00 right now so what the hell. i called high caliber anyway and got my name on the list so i will run the dd until it comes in

Maybe run the DD and see how it shoots...you might be surprised. I can tell you that DD lite rail III is a damn sight better than the old KAC or PRI rails

A recommendation only (and will get you quite a rifle):

Get a standard Colt, FN, or BCM flat-top 20-inch 1-7 or 1-8 twist rifle (a semi-only clone of an M16A4); add a Geissele trigger; free-float the barrel (A Daniel Defense Omega 12.0 or Larue 12.0 or equivalent from one of a dozen or so manufacturers); add quality handloads (a 77-grain Sierra, 75 Hornady, 77 Nosler, or 73/77 Berger); add your scope; go to work to 750-odd yards (depending on your altitude and conditions).

Military M16 SAM-Rs and DMRs are variations on a theme using specifically-made match barrels.

I have a hard time agreeing with this. People seem to say it a lot.

I understand the purist mentality but goddamn... its a stainless barrel that seems to be of quality AND WITH the step for the ops/AE collar... so ur telling me the rail and upper receiver are what make the issue mk12 a mk12?

I fckn love my HCS built mk12 mod 1 upper to death but please tell me what truly separates the DD then? An antiquated overpriced rail?

For the people not totally comfortable with building an upper from the ground up at home I think the DD mk12 is a great opportunity.

I just don't see how they're soooo different. Minus a few cosmetic easily replaceable parts.

One last question and it was mentioned earlier they are in stock at swfa. With my nightforce nsx 2.5x10x42 will i want arms 22m or 22h rings. Thanks to everyone

you'll enjoy it even tho its not "spec". I love my 20 inch AR the most out of all of them that i own. Gov profile barrel and a 16.7 NSR rail, i wasn't trying to clone anything but its a damn shooter with 77gr handloads.

*You're. "ur" is a term used by mental 6-year-olds when they're texting their friends because parents think it's a good idea for children to have cell phones. ;) Since we're all presumably adults here, perhaps type like one? :)

A Mark 12 is a combination of specific parts. If someone is going to claim their rifle or upper is a "Mark 12" and it's not the same parts, then it's not a Mark 12 clone. Period.

There's a list of requirements. Either they're met or they aren't. Nobody is saying that if they aren't met, the rifle is shit. Far from it. I'm sure what DD calls their "mark 12" is a fine quality piece of gear. But it doesn't meet the requirements of a Mark 12. Thus....it's not a Mark 12. And DD ends up looking a bit of a prat for calling it that.

The simple fact that youve resorted to grammar as a reply back shows how little of a point you have to make. I sent my first reply from my phone and I could care less about what ur I use.

Like for example. Ur an idiot.

The list of requirements were not specific name brand parts but a combination of "good" parts that were only available in 2001-2002.

By the way. It isnt MARK 12... its mk12 ... its pronounced Mark but it isnt spelled that way. Its the Navy's designation. its two letters not 4.

The requirements of a mk12 werre a FF rail, a stainless quality barrel and thats about it. All the DOD wanted was a rifle that was simply more accurate then an m4 without going to a full standard bolt action rifle because of weight and inability to work well in close quarters.

What the military issued is yes a list of specific parts. Because they were readily available. Not because they HAD to be that. DD doesnt claim theyre a clone. Hell I dont see ur panties getting all twisted over BCM calling all of their mk12 variants a mk12 upper, what with a DD rail on one of them?

Your definition of mk12 is skewed to only think a mk12 is one that was issued part for part. That wasnt the requirement for the program.

For the record i didnt spell check this one either. Have fun.
 
#22
I agree with the idea that safely guarding the term "mk12" as Some type of Holy Gail is BS. While yes I understand if it doesn't meet the specs then technically it's not a "mk12". Well that's why I set out to build an 18" SPR rifle that I now call mine "better than a mk12" so I don't have to argue with people over this silly shit. I'm happy because it's what I want, it shoots like the business, and I got to name it ;)

So no worries here I won't call my stuff a mk12 or a mk12 clone. Folks act like your stealing the trademarks to Coke or something. It's silly and a waste of time to argue over and debate about. Like I said no clones here, just better than...

He clearly just doesnt like Daniel Defense for whatever reason. Me personally I do like them. They build quality rifles and parts, PRICEY yes. But quality isnt cheap. Even if it is overpriced. Lets not get started on that topic... (KAC).

The fact that DD went as far as to put the step on the barrel for the ops inc collar tells me that they do care about how theyre representing the rifle theyre depicting unlike DPMS who also claims to build a mk12. In 308 and 223/556 lol without the step for the correct brake and collar.

People get so edgy over other peoples claimed mk12's like it lowers the value of theirs...

Heres the specs to an extent.

So if I use a Vltor upper (which is better than a standard forged upper) but everything else is the same then it's not a mk12. I ask cause according to that site it doesn't specify what upper.

God knows if I built one with a Vltor upper and everything else was to spec and I called it a mk12 I would be stoned, tarred feathered, etc. See my point?

How did I get lumped in with the purists? Ive been saying since my first post in this thread that its ridiculous how up tight people get over what parts were used by the military. And if they're not used the rifle isn't a mk12 by any standard.

I'm on ur side lol. Re-read my posts if necessary. You asked for the specs of what WAS consistently issued and that's what I provided. If I misunderstood you, my apologies.

I see now you didn't ask for what was a TRUE mk12 but rather what makes it one.

Like in my previous posts I said the key is the barrel with a free float rail really is all. An accurized m4 of some sort.

Most of the uppers were colt uppers because that's what the military has in their inventory.

By all means use other parts. I've got no problem with you. Its the people that cry about Daniel defense making a "mk12" and equating it to a fiero vs a Ferrari that I will call out.

By that comparison, Daniel defense didn't use a stainless barrel or that fieros used Ferrari motors. The heart of each rifle is nearly identical.

No sweat. I was also agreeing with you, and trying to prove a point about this holier than thou mk12. I'm a DD fan too because they make good stuff. No worries brother, I know where your coming from.

Oh look at you reading my thoughts and everything!! Your mother said to tell you she's so proud of you. :D

as for BCM's MK12-labeled gear, I tell people the same thing when they ask. nobody asked in this thread, so there was no point in bringing it up. I see you didn't let that stop you from using your jump to conclusions mat again. :D

for the record I actually like DD's products quite a lot. but don't let facts get in the way of thinking you know a single fucking thing about me, sweetheart. you just go on pretending on the internet.

Cute gif really lol.

I didn't need to claim to know you by simply seeing your distaste for any rifle similar to an issued one and built by anybody that isn't CRANE or unit armorer. And one that's sure to be quality any way.

Facts are the only thing you've left out from this stupid spat on a forum. Fact is its a mk12. Its an accurized m4 just like the military asked for. Not built with true to issue parts but gasp, possibly better?

I'm elated to be part of your ignore list, I'm sure its full of other guys that dared to call you out on your pathetically watered down knowledge of what a mk12 rifle was intended to be. Hell probably just full of guys that dared disagree with you.

Tool.

I tend to agree that if you are going to call something a Mk 12, it should be a spec Mk 12, not just an 18" precision AR.

The flip side of that is that spec builds are cool for what they are, but you can probably do better for less cash outside the confines of a true spec build.

The following pages show lists and figures of the configurations of the 5 SAM-Rs and 3 M-16 A4s that we used for this testing. The SAM-Rs are numbered for reference to table 1. We assumed that there was no difference between the rifles performances. However, the precision values from SAM-R 1 were found to be significantly worse (by more than 20 percent) than the other SAM-Rs (t-test, p < 0.03). The figures also show the optic used with each SAM-R. All SAM-Rs were built to the 2-MOA specification. They were new, with no more than 150 rounds through them. They were fitted with Harris swivel bipods HBLM-S and A.R.M.S. quick release bipod mounts.

SAM-R 1
- Olympic Arms FIRSH free float tube

Thanks to everyone. I didnt mean to cause any disagreement. I got the dd to get me through the summer. And Kevin at high caliber sales is bulding me a mod1 so i will get to see in about three months which one will stay. Cant really afford to keep both but ill try. What lower should i use for the hcs upper. like i said i got a 3 position usm4 with a tac con trigger but that was gonn be used on anight vision hog setup. Is there no way in hell to get a crane marked lower. Again thanks

Haha I'm with trespasser, NO!

I'm thinking ul like the HCS upper better overall. I love mine. Shot it out to 605yds today. A 10mph variable wind will stomp you quick.

I'm very interested to see how that Daniel defense rig does.

Shoot some black hills 77gr otm through it! Id like to hear. Oh and I wouldn't use ARMS rings unless ur really trying to go clone... they're lower quality then most cantilever mounts these days. I went with a nightforce one. Its not QD but I don't feel it needed to be.

Also as far as a lower... I'm a fan of fixed stocks on my mk12. I tried a LMT sopmod lower on it but it just didn't quite feel right. I went with a plain Jane A2.

Also buy yourself a geissele ssa-e and ur good to go.

I didn't read all the comments because there is so many. I run a Barnes precision cqb rifle with a 18" barrel. Put a UBR stock giesselle ssa, and a vortex viper pst 1-4. Shooting under .190 5 shot group at 100 meters. Only complaint is I should of went with a higher power scope. I love vortex so I'm currently looking for a 2.5-10 I love this rifle and I feel it will fit your needs very we'll. FWIW I SPENT 1260 on the rifle and it comes with Magpul stock and sights.

DD MK12. Why Not?

Someone please school this old retired Navy Pilot as to exactly what a real and genuine MK12 is/was? Who was the contractor for this platform for our troops? Was there only one? What exactly did it do or have that the later versions such as the DD MK12 don’t do? Why is the original article (if one exists) better than the follow on’s?

It has seemed to me that over the course of history of this country’s military, many different companies have been commissioned and won contracts in times of war to build “mil spec” weapons platforms of the same type, M4, etc. whatever, pick one. Machine a part to the exact tolerances and specs, made of the same materials, what is the difference?

I currently have two AR’s, a Colt Military/LE M4, and a Noveske N4 in 300BLK with AAC 7.62 can. Both with great optics on top and great triggers underneath. Now I want a medium range marksman type platform and the DD MK12 looks to fit the bill.

They have gotten excellent reviews from any and everyone who actually owns or has tested one. The only negative comments seem to be coming from those who have never laid their eyes or meat hooks on one. The hammer forged barrel and chamber are yielding sub .5 MOA groups. Ringing gongs at 800 meters with 77 OTM’s seems to be commonplace. At around $2K and everything you get with this rifle (check the web for specs), I think I see one in my future. Perhaps topped with a Leupold MK6.

Google is wonderfull for this kinda stuff....Like typing in MK12 or Special Purpose rifle and reading the first hit that comes up.


For everyone else,

DD "MK12" is not a MK12 and should be renamed on principle alone. Armored Ferret is 100% right, people need to stop giving something a name that is reserved for something else. Either you don't understand it so keep quiet or you do and are just dumb.

Words have meanings, use them. Do you call a Dodge a Ford? Do you call a BCM rifle a Bushmaster? Would you call a MK18 a MK12?



With all that being said for the OP, there a much better setups than the MK12 various mods. Its a 10+ year old design and we have come pretty far since then. If you want a good shooter and a clone for nostagia, have high caliber sales make you a MK12 Mod 1. You want the LEAST ammount of ARMS (none really) that you can live with. Ive built a bunch of MK12 type rifles over the years and to be honest, the SPRish rifles are much better than strait clones.

WOA 18" SPR + quality upper, good light FF rail BCM KMR, adjustable gas block and a good BCG from any of the top manufactures will shoot as well as anything out there. If you shit gold cufflinks, go with Lija or Krieger for your tube.

I have a >90% spec MK12 Mod 1, upper by Monty at Centurion (who does them right) and finishing out the lower to get it into the rest of the specs with the KAC trigger and mount the NF x24 up. Biggest spec shortage I have is the receivers themselves but I don't give a shit about that, they're on JD/Sniper's Hide forged and I like it that way. It's been a labor of love really, don't know why I really went after it but I did more out of stubbornness than anything. The final add will be the Allen suppressor which will go well with my Mil-R Nightforce x24 optic sitting in a NF Unimount and the receivers. Not exact, but good enough for me. I'll still call it a MK12 Mod 1 too; I think I'm close enough to the specs for that.

What I'll say is if I had to do it over again, I would have gone a fair bit differently. The SPR is a niche rifle filling a valuable space for those wanting to shoot distance with a semi, yet want to actually carry it in the hills as well. It's also good for ammo commonality if that's important to you, but let's face it that there's better options for a small frame AR when distance performance is what you want.

How I would have done it if I was spec'ing an SPR today: 6.5G, JP 18" lightweight contour barrel, Seekins Receiver set with 15" BAR rail for weight savings and practicality, Nightforce 2.5-10x42 Mil-R, Geissele High Speed Match trigger, CTR stock.

I do believe there are/were Mk12 barrels made by Lilja, so that wouldn't be far off. Also, i've seen every variation mentioned here but for the MK12 Holland. I have a mod 1 but should have went with a holland clone. I'm surprised that i don't see more of them considering the purists fetishes.
