I’ve got a lot of catching up to do to get on your Gucci gun level haha!

 

[Greywolf36]

You don’t find these everyday! A good while back there was a “Hide Group buy” and I chose serial #’s 2,12,13
I just put the first one together in 6.5 CM. Not sure about glass yet but can’t wait to pull the trigger on her.

AR-10 DMR
• 18" custom Bartlein barrel/ OD green cerakote and blended muzzle brake (turned by Craddock Precision)
• Superlative arms Titanium adjustable gas block 10 clicks on restrictive mode
• JP Enterprises Fmos bcg (having issues)
• Aero Precision M5 upper, Receiver face trued and lapped then set with loctite 620
• Aero M5 lower
• aero S-one Handguard
• Magpul PRS Lite stock:
• 3.4 OZ Buffer weight
• Springco Orange spring
- Carbine length buffer tube
• Geissele Super charging handle
• Large grip, Anarchy Outdoors precision
• LaRue MBT2 trigger

I'm a newer shooter, and was still able to consistently hit Sub MOA at 600 yards with this rig.
Working with Craddock Precision to get my 18" Bartlein barrel was a phenomenal experience.... great team over there.

Bought my first Armalite 308 in '08.
Didn't like it, so it sat in the case, neglected for many years.
Didn't like the carry handle, didn't like the Kenner SSP style charge handle, and didn't group worth a damn.

Then china bug happened, and the plant I worked at shut down for nearly 2 months, and I figured what the hell, I'll make it into something I did like.
Had been trying for years to buy a flat top upper from Armalite, and they never had any in stock.
So disassembled it, and went after the carry handle first. After machining it off, made a custom rail that saddled down over the upper so it was at the same height as the front tube.

Next was to rid it of the SSP charge handle, and picked up an FAL handle, and some steel stock, and made it into a non-reciprocating set-up.

When it was all the way down to pieces, found one of the accuracy issues, the pinned & welded brake was hiding one of the worst damn muzzle crowns I had ever seen in 50 years playing with firearms!
It looked like it was done with a hand drill, using a dull countersink bit, scored, and off center.
Pretty sure this thing was slapped together at Armalite, and they figured that once the brake was on, no one would ever see that horrible workmanship.

Same went for the front of the upper, wasn't square with the bore by at least .005". No wonder I had to have thee rear sight cranked almost all the way off to one side.
Anyway, re-crowned the barrel, trued the front of the receiver, and bedded the barrel.

Now it shoots pretty damn well .

And as you can see, I like my front sights at the front of the barrel. All my ARs are built this way.
Glad that I didn't trade the old girl in 20 years ago.

That's not my style but very cool nonetheless. Nice to see some out of the box thinking.

 

[cressida]

Yeah, not what I really wanted for a big bore either, but since the original purchase, found an Armalite 22" upper, that was kept as a option.
Later decided that having one buffer/spring & trigger tuned to a 16" barrel with 150 grain ammo, and thinking I could just swap out the upper that used a heavier projectile was not going to work out very well, so found another lower to build a dedicated long range 308.
Gathering parts now, and will be doing another FAL charge handle conversion on it.
Thankfully, it's already a flat top.

 

[BCP]

The FAL charging handle is cool as hell.

It’s actually really good in this host, in its fully stock form. Instead of ejecting at 4 o clock it’s at 3.

I hear a lot of other guys go through hell tuning their MWS’s for suppressed use.

 

[Triggerslapp]

What do you think of the PSR7 can?

I really dig it. It’s light, low backpressure, pretty quiet, and I love the mounting system.

On this host, almost no tuning is needed. It went from 4 o clock to 3 o clock ejection.

Yeah I’ve read that as well but am looking to use my surefire for the same purpose. How’s the weight?

It’s light. Very light. Lighter than the Socom 762 by quite a bit.

Oh i meant the rifle overall

 

[Triggerslapp]

Oh i meant the rifle overall

Oh gotcha. If I remember correctly, It weights roughly 12-13lbs as shown with the scope, bipod, and can. And a loaded 20in mag.

 

[jMarine]

I'll play. Just got my upper back from d.wilson. They did a great job on my KAC URX install. This is a 1moa shooter all day long, maybe better for someone more seasoned at shooting gas guns than me.

Edit: don't hate on my 10x SWFA. After 1.5 years I have not decided what optic I want for this rig and the 10x I've had lying around as a "test scope"

 

[5RWill]

That’s not bad at all

 

[kthomas]

There's relatively little standardization in big block gun components compared to that we enjoy in small block guns. Sometimes you end up with a combination that works. Sometimes you do not.

I've used KAC big block rails with SR-25/DPMS pattern receivers.

Some KAC stuff doesn't even work with other KAC stuff. I've had to hone out KAC URX barrel nuts - just to get them to fit over first generation KAC SR-25 barrels.

I love the look of the URX 3.1's, best looking rail IMO.

Great looking rifle!

KAC URX 3.1 is hands down the best looking large frame handguard

Did you have to do anything to put the mb762 on there? Or it just slid over? How was the weight and what length is the urx? Fantastic looking build.

no it just slid right over. the URX 3.1 is the standard SR one with the gooseneck, probably weighs around 16lbs with all the stuff on it. Thank you for the compliment, I have to find another can of aervoe field drab so I can paint all the unpainted parts to match the rest of the rifle.

A blast from the past, around 2014, for you URX fans:

A blast from the past, around 2014, for you URX fans:

this image and the video of chris costa shooting his 6.5 barrel SR25 are what pushed me over the edge to impulse buy all the parts for my AR10. I saw that knights had the 3.1's in stock and impulse bought one when I got off work.

@mj23polaris
nice builds. nice range, also.
IMHO, large-frame AR-10 6.5CM's are allowed in this thread. I don't think you're the first 6.5CM in this thread, either.

^^^ Nice Setup. Makes me want to have mine finished

Gathering All the Parts Now for Mine
Think I Will Go with:

Mega MaTen Monolithic 12" MLOK Upper and Rail
MARS-H Lower
Ranier 16" Intermediate Gas Cut Down to 13"
TBAC DOMINUS

Will be my night hunting setup

Say @thestoicmarcusaurelius did you ever get around to putting this setup together sir? Pics?

 

[Convex]

Thank U for the very kind words.

Never fails, a build is work/sweat, but there is a "payoff" at the end.

Take Care

S&B PMII 5-25 T3

Freshly kryloned in a 3 color Rust-Oleum.

Loves 42gr of H4350, Hornady Brass, Federal Large Rifle Primers (non match), and 140ELDM bullets. Velocity in NH is about 2720fps with the load. Shoots 3/4MOA groups from prone. I don't think I have seen it over 1MOA in the 500 rounds through it.

Its a SIG can, no?

Yup! The 762Ti QD I think.

Is the PVS14 a helmet mounted or rifle mounted setup? Pretty sure you can actually do both with those right? Plans to mount it on the rifle and smoke some hogs at night?? Always wanted to do a nighttime hog hunt man, that shits legit. Some guys we lease out land to have NV kit they run while setting up over bait.

You can mount a 14 to a 5.56 (nothing more for recoil), but would highly recommend against it.

1.) To scan you are going to be aiming your rifle at everything.
2.) You can’t put them behind magnified optics.
3.) A red dot or similar may “burn” a permanent black spot into the tube even on a NV setting after extended use.

I would helmet mount it and find a laser to mount. Even better, helmet mount a 14 of goggles (much easier to move around with), then put a thermal on the rifle. Even with super high quality tubes, sh*t blends together really quickly outside of 100 hundred yards (animals have great natural camo). They can’t hide from thermal.

I had no idea you would burn in a black spot on mounted pvs14. Makes sense though.

 

[NHPiper]

To be safe you would only want to turn on the dot (again even on NV settings) when you are about to engage targets. Or do the same with the 14. If you out there scanning with it on a rifle (not ideal) for extended periods of time, you will likely regret the blem in the tube.

Looks great!

 

[stormhammer]

Picked up my first AR10 today - a pre-merger MEGA Maten receiver kit. Came with an RPS trigger as well - prior 308 experience was with a PTR91 and then a SCAR17.
Honestly torn if I want to go mroe long range ( not many around me to make use of ) or more battle rifle type. A P&W 13.7 sounds like a bundle of concussive fun

Now to find a DPMS High handguard

maybe you can get another slant-cut upper? then build both!
