Hey all,

I am in the process of building an SPR type AR. I had a precision based platform(but being ignorant I jumped on what I thought was a good price for a bull setup, only to find it was a 1 in 10 twist... (for those that don't the AR/5.56 round... bad things...) so I could not acheive the accuracy I wanted.

I was pulling about 1.25-1.5in groups at 100 yards.

I have a barrel and upper on order now, hoping to be able to get this one to group tighter.

So who's got precision ARs? Advice? tips? suggestions?

Pics???

To start things off, here is my old setup:

Re: How many have precision ARs

I've got a RRA 24" bull barrel, 1 in 8 twist, all stock except for light weight trigger springs. Nikon BM 6-18 soon to be replaced. It shoots 5/8 to 3/4 MOA at 100m all day with reloads. A 1 MOA groups is pretty dissapointing. Shoot mostly 69gr Nosler CC. The other day I did have my first .500" group, was actually shooting 52gr Nosler CC's. Your 1 in 10 twist should be giving you better groups, what brand is it? Accuracy should improve with a better trigger and more trigger time.

Re: How many have precision ARs

I've built a few in my day, and each time have decided to go shorter and lighter. I can get the same accuracy with the lighter guns as with the heavy ones. I learned the hard way that a portable precision AR is not only extremely valuable, but easily lost if you're not careful. If I want heavy, I'll settle down behind one of my heavy bolt guns.

Your current rig looks a bit heavy in my opinion. You might consider (if you haven't already) taking a hard look at your chosen barrel length and profile for your next build.

I like that IOR. An AR platform is a great place for IOR's short-spaced turret design. And you save some weight by not needing a one-piece cantilever mount.

Re: How many have precision ARs

The 1-10 twist barrels, you will probably find it shoots better with the real light bullets. Try some 45-55 grain bullets.

We make precision AR's, all of our guns are 1-8 twist, but we don't build bull barrels unless someone custom orders one. Standard barrels are 16" and 18". I've shot out to 800yds with my 18" and hit a half IPSC target.

Good looking rifles guys.
 
Re: How many have precision ARs

Great looking rifles guys!!!!

The one above is a DPMS Bull barreled upper. and it is heavier than anything! I recently sold it and have a SABRE fluted 18in SPR barrel on order.

I shot as low as 55 gr with that 1in 10 barrel and things just would not tighten up. I know it was not just me either. I took that gun down to train with Vern at CVT and he got behind it. He was down to about 1 moa, but not much tighter than my groups. We shot out to about 500 yards that day. wind was really rough though and throwng the light bullets around like crazy!

I love the clarity of the IOR, but its a heafty mother!!!
I actually have it up for sale on a couple other boards, I'm looking for something a little lighter and lower mag level.
maybe 2-10 or so.
 
Re: How many have precision ARs

Current SPR-18" WOA SPR barrel, Vtac forearm, waiting (still) on my UBR through DPMS, ST10 w/Jpoint backup.


Next AR will be 16" and use a barrel/components from Specialized Dynamics.
 
Re: How many have precision ARs

Mine is a LAR lower with RRA match trigger system, M4 stock, and a DPMS 16" Low Profile upper. With the Millet DMS-1 I have on it I've been getting 1.5" groups at 100 yards off a bag. I don't know if you can really call it a "precision AR," but it's reliable, light(er), and it didn't break the bank. Works for me

Re: How many have precision ARs

Here is one of my favorites, the barrel is 20" and I think the 18" would be a bit handier w/out giving up much speed.
This one is chambered in 6.8 and shoots very well with bullets weighing from 85-130 grs.

Man, I hope that little fury thing isn't in AZ. I guess it could be one of those roof rat things the news talks about on the west side.

Re: How many have precision ARs

I've got the RRA Varmint with a 24 inch tube, 1 in 8 twist, and she does sub MOA regularly, and i've done some pretty small groups with black hills 68 heavy match and 69 gr sierra match kings. Great varmint gun, tips the scale around 16-17, so a tad hefty if you don't like that. I've got the Elite 4200 6-24x50 tac scope on it, and she picks off crows, woodchucks and have even nailed some deer with it in deer management season.
 
Re: How many have precision ARs

I don't spend to much time shooting really small groups at 100 yards, but both of these rifles do shoot sub-MOA groups at that range a couple times a year. I spend most of my time shooting them out to 600 yards with the occasional journey out to 800 just to make sure I still know what I'm doing.

IMG_2151Large.jpg


Both are 18" barrels with 1 in 7 twist, shooting 77gr. handloads.

Re: How many have precision ARs

About as precision as it gets in my collection as far as AR's go is my 6724, pretty much bone stock with the exception of added a JP trigger group to it.
 
Re: How many have precision ARs

I've had a couple JP CTR-02's. My current one is an 18" mid weight barrel. Last time I had it out to 300 yds I was consistently getting groups a hair over an inch, 1.0_. This was with the Burrix 1-4 XTR I was working with for the Ft. Benning 3 Gun. Ammo is Black Hills Reman 68 gr. You don't need a super heavy barrel on an AR for accuracy.

Re: How many have precision ARs

Recently put together a 6mm AR wildcat (6mm RAT) that makes the small format AR into a truly precision rifle. 1/2 moa groups are the norm with 105 Amax, 108 Bergers open up to .7 size groups. Stays supersonic past 1200 yd. 22" barrel 1 in 7.5 twist and it still weighs less than 11 lb. with a SN-3 1.8-10X44. Only had it together for a month, still fire forming brass. Have had 4 other people shoot it and they all have a big smile after ringing steel at 800. Can't wait to try it out on yotes this fall.

Noveske upper, Geiselle, Colt lower, Surefire

I have shot this sub MOA out to 825 yrds. It is by far the most fun thing I have for 300 - 600. RE 15 77 SMKs, does just fine.


Good luck
 
Re: How many have precision ARs

The 3 most important things to building an accurate long range AR are barrel(at least 1-8" twist) , trigger (top line single stage), and scope(clear and repeatable).

This is the SR-22 Viper built by Volunteer Armory in Tennessee. It is very accurate out to 800 yards.

Re: How many have precision ARs

Running a DPMS SASS. This rifle has far exceeded my expectations of how accurate a gas gun can be. Fixing to run this rig on duty after a few add-ons. Working a rural area, an accurate semi-auto in .308 definitely has it's benefits from a duty stand point.

Currently running a Leupold LR/T M3 model 51850 in XTR's and planning on piggy-backing a Burris Fast-Fire along with it. Added a Streamlight TLR-1 off the left side for lo-light work. The grip is getting changed out as well.

Re: How many have precision ARs

BM Custom Shop PMR, 1 in 7". So far, I've shot it only once with 69 gr hand loads, and the groups are nice and tight. Will try the 77 grainers one day. I recently popped off the Mk4 and put on a NF 5.5-22x56, and looks much better. Will post new pics when I take them.

Sorry for the delay sobrbiker883, been real busy lately.
Here are the pics you requested. Top ones on manilla paper are 3 rounds & bottom ones on white are 5 rounds. I started using 5 round groups because of some advice on this forum. Short of the one with the high winds & the one at .359" & .301" all are 1/4 moa or less. It all depends upon how much expresso i have before going out shooting or how much wind exists. As you can tell i'm not the greatest at reading wind velocities. Gusts were determined from the local weather station. My friend with the kestrel wasn't there that day.

Nice. You shoot in January in Michigan? I see I'm not the only one crazy enough to fight the cold. Good shootin.

I had an AR built just for coyotes. RRA upper and lower. YHM handguard. Krieger in 6 WOA. Built by Dan Carey outa Az.

Re: How many have precision ARs

Yes i'm a little bit crazy to shoot in the winter but that is how it goes when you live in the northern states if you want to shoot year round. I shot many years ago @ 350 yds with a friend of mine in a snow storm almost white out conditions. We were trying to hit a 12" steel plate. We hit it several times but missed many more. It was very difficult to see the target. Judging the wind gets easier when all you have to do is watch which direction the snow is going; ya know how horizontal it is.

Nice groups, and nice shooting for sure. But I meant 5 or more 5 shot groups on one target that average .3 moa or less, not a bunch of cut outs laid on a notebook.

Something like this with five five shot groups:
SHGrouptarget.jpg


Not to knock your shooting, or the rifle/load but 1/4moa all day is assuming that the rifle will hold 1/4 moa all day, not cherry picked groups. What you have there is 81 selected rounds over 9 months and 536 rounds fired.

I just have a little problem with the term, it gets tossed around way way too loosely, esp online (that's why LL came up with the little target pictured).
 
Re: How many have precision ARs

I think its so funny that people feel they need to prove to someone else that they can shoot or that their gun is somehow better than the other guys who has the exact same gun. I could give two shits if anybody ever knows what I can do but thats just me. Can anyone explain to me why people go to the length of lying about what they and their gun can do? For example why do guys post one 3 shot group that measures 1/2 inch at 100 yards but fail to mention that they shot all day and picked that one group out of a bunch of crappy ones and then proceed to tell everybody the gun will do it all day long " if they do their part" I get a kick out of that line.
 
Re: How many have precision ARs

I can't shoot groups for crap. Every once in a while I get lucky. I find myself a submoa load for my rifle, test it at 500 and keep loading it until the barrel goes......

"all day" just gets torques my skivvies for some reason, probably because I shoot with too many really good shooters, and everyone I know has bad days and good days.
 
Re: How many have precision ARs

To all those that claim,... all day, any day, I'll give ya up to up to moa groups.
All you have to do is get invited to HardRock, clean the course shooting moa or under, 20 shots total, 5 each at 600-800-900 an 1K,... no sighters within 20 minutes,...and you will impress a hell of alot more folks in person than you ever will, on the internet shooting range. Talk is cheap, but HardRock is there in living color, to humble even the very best,.... .com shooters.

Sobrbiker883,

You are correct i didn't know what type of target you were looking for. I have saved the one you posted for future use, thanks. I didn't know that target existed until you popsted it. You have to understand a few things though. For my 20+ years shooting i have never saved all of my targets until the last 2 rifles i recently purchased, i just kept sheets of paper with round counts for each rifle so i would know how many it took to burn out a barrel & occasionally cut out targets to keep. When i go out shooting i bring 3-4 rifles. It is very rare that any rifle shoots a complete target which has 4 bullseyes on them. My original targets had 1 bullseye on them. That is the reason for cut outs from each target, not cherry picked ones only for viewing pleasure.

I use a uncle buds bull bag up front & a sand bag at the rear. I've always based my life upon being honest & that is the only way i intend to be. I know you didn't mean any harm in your post, you were just trying to clarify your point. I agree there are alot of BS artists out there but i am not one of them. In the future since apparently some people don't agree with the way i keep my log books, i won't post targets or mention MOA, i'll just say X-rifle shoots well to avoid this in the future. I've spent too much time explaining this already & don't intend to do so in the future.

I have almost finished creating my log books for all of my rifles the way i want to. There will be only 2 log books with all of the targets that were shot with them. One will be cutouts since it saves the most space in my books. The other one will have complete sheets showing all 4 bullseyes since that is the one my son is using as his first target grade rifle & i want him to see his progress over the years. The only reason i am starting to keep all of my targets is because a friend of mine recommended it & i agree with him that it gives a better record of the rifle, including developmental loads.
 
Re: How many have precision ARs

So far I haven't been able to work up a load, but my SPR build with a CLE 1/7twist 18"barrel from a douglas blank shoots 1 MOA with cheap S&B ball ammo.

I've got a box(500) of 77gr SMK's just waiting to have a load developed for this rifle.

Re: How many have precision ARs

Salmon, nice looking stick.

Did you go with CLEs standard varmint contour or did you opt for another?
 
Re: How many have precision ARs

Just about any AR-15 with a match barrel and float tube will group tightly. Have built 2 AR-10 T uppers and an A4 Service Rifle Upper that each buyer praised highly. Not much on Quadrails or BUIS, and have no need for the MagPul sniper stock due to its weight. Hard to go wrong with White Oak; nice people and a Great Product! Armalite, White Oak Armament & Precision, RRA, and Noveske are what I have owned, and all performed great.

Like the JP Entp float tube and the Badger Ord Stabilizer Handguard. Very much like A2 configured rifles. Have yet to send a detach carryhandle to WOA to have their pinned rear sight installed, but mean to. Have yet to try a Gieselle trigger, but mean to. Always fighting the weight battle. Always intended to drill one of my SR float tubes to lighten it up, still mean to...

Handloading is the only way to go. 75 or 77gr match bullets are just beautiful performers. Have one pac-nor WOP barrel with 1:6.5 twist and several hundred 90gr bullets for longrange. May just be loading them up soon.

Do like the LaRue LT101 QD riser. Enables you to swap scopes to other picatinny rails which the Unimount or LT104 won't allow. Have 3 of these and they work great.

Hard to beat the leupold 4.5-14, or 1.5-5, or NXS 2.5-10 for lightweight, great performing scopes for these rifles.
