308 AR10 Build Info/Picture Thread

[Daddyusmaximus]

My effort to make a decent compromise in a.308 AR, and I'm pretty happy with the result. However, now that I've got the precision bug, and have found this place, I may try a conventional scope, with a bipod and see what she can really do. She'll never be a long range gun seeing as how I made her short, and handy, but I would like to see just how much accuracy I can get out of her. I do have a 4-12x44 Vortex Crossfire II sitting around not doing anything... It may lead me to getting her some real nice glass if I can find a load the BA Hanson barrel really likes. So far, she's hovering just around 1". ( a couple groups just under) That's with the PA 1-8, and in keeping with the BA accuracy guarantee, (168 gr FGMM) so I can't complain...

Receivers... Aero Precision with their LPK
Barrel... BA Hanson 14" with pin-and-welded Warcomp
Rail system... Midwest Industries
Scope... Primary Arms 1-8 with the ACSS reticle
BUIS... Troy with tritium
BCG... Lantac enhanced
Recoil system... JP Captured
Trigger... Geissele SSA-E
Furniture... Magpul CTR stock, MOE grip, MVG M-LOK
Weaponlight... Surefire M300 Scout Light
Leftover ambidextrous safety that I can't remember where I got...
Leftover scope mount... same deal... just happened to work out well.

Also of note is the barrel twist. It's a 1/10. Everyone makes barrels in 1/10 these days for the heavier rounds. I got my hands on a stash of the 130 gr Federal T762TNB1 as I figured a short barrel round would do well in my little 14"gun. Turns out it's quite expensive to find an AR barrel in 1/12 twist... This one shoots the heavier rounds better. However, at close ranges, it's still plenty accurate for a combat rifle with the PA 1-8 at the ranges I'd see in my AO. I may try some 175s once I get more scope on her, and the ranges open up again.

Nice rig. There are a few manufacturers that make 1:11.25 twist 308 barrels. My 20" BA has no problem being sub-moa with a 1:10 and 150gr or 168gr ammo. They all will like to eat different food though

 

[Mike Shoots Stuff]

Here is mine.
80% Lower from a gunshow
DPMS Upper, JD Machine BCG, Criterion M110 Contour Barrel by Fulton Armory. CDNN $89 Fore end.
Geissele NM Trigger. The rest is pretty much all from Fulton Armory. I bedded the upper and lower to eliminate movement.
1st is how I have it set up for NRA Long Range.
2nd is some groups after bedding.
3rd is where I bedded the lower.
4th is it's "tactical" or practical competition set up.

When a customer signs up for his third custom rifle, you know what his expectations are - high. I don't think this will disappoint him: 20" 6.5 CM with Bartelin 1x8 barrel from Craddock Precision. Seekins SP10 Builder's Kit, currently made of Unobtanium. Area 419 brake - both super loud and super effective. Dialing that gas down with the usual SLR adjustable gas block. JP FMOS bolt carrier group with JP High Pressure bolt. Geissele Super Charging Handle. JP SCS in 7.62 H2 weight. Trigger Tech Black Diamond (It's actually RED, you know ....) dialed down to 2.0 LB. Cool plastic stuff by Magpul. Cerakote by We Plead the 2nd. Nightforce ATACR F1 4-16x42 with TreMOR3 reticle in Spuhr SP-4026 mount. Fitted hard case by Patriot Cases. Bare rifle weighs in at 10 LB 2 OZ. With scope and mount plus empty magazine 13 LB 2 OZ. Shot way-sub-MOA with Prime 130's at 100 yards from the start.

Outstanding, per usual. Seekins style on their rails don't do much for my tastes, but I appreciate the quality & functionality.

She my budget QWEEN

Best groups 3/4 of an inch (5 shot)
Have had much tighter 5 shot groups around .3" but including a flier brings it to about 1". So I wont count em.
For the money, she runs and prints sub MOA all day.

I'll play. I have two Armalite AR10's. One was my first, started as an Armalite 24" T upper with a Lothar barrel. Had it cut and crowned to 20". At the time I was in CA so I had to put it on an Aero Precision lower when they were building them on the same forgings that Armalite used. Only difference was the rollmark but it was CA legal. It has Armalite Match parts including the two stage trigger and oversize pins, EGW gas block, SWS E1 hand guard, Magpull trigger guard, Armalite BCG, rifle buffer and spring, Hogue grip and A2 stock. Optic is an older IOR 3-18x42 (probably some of the best glass I own)and I'm not sure what the riser is.

Last time I had it at the range, ten shots at 200 yds. FGMM.

This is my other AR10, more of a battle rifle. Another Armalite on an Aero Precision lower, this one started with a 16" Lothar SASS barrel mounted to an Armalite upper and BCG. The barrel got a glass bead job, Vortex flash hider, EGW gas block and BCM chargeing handle. It also has a SWS E1 carbine hand guard and a Hogue grip. Lower has a Geissele trigger, Magpul trigger guard, oversize match pins and Armalite carbine buffer and spring along with the Vltor IMOD stock. The optic is a USO 1.8-10 x 37 on a Bobro mount and (IIRC) Troy BUIS. Sling is a BFG. This rifle is every bit as accurate as the 20", both shoot .5-.6 moa with FGMM ammo.

The Lothar barrels above both have 1:11.25 twist.

 

[louu]

Man there are some incredible rifles in this thread!

Here's mine, nothing special just a springfield saint 308 with a guessele high speed national match trigger with the light spring.

This is the first time I've bought a complete AR, All my others were piece together.

Damned fine group. I am impressed.

Damned fine group. I am impressed.

Thanks. A lot of people were, me included. I'm really not that good of a shot...it was just one of those days where all the planets were lined up. More luck than anything other than it is a very accurate rifle. I've never come close to re-producing it.

 

[Montyman]

Here's my latest build. Started with a 5d tactical 80% lower and Aero M5 upper. Magpul PRS stock and pistol grip. Velocity MPC trigger and Radian ambi safety. The upper has a JP handguard, over a Faxon heavy fluted match 20 inch barrel in .308 with a Superlative adjustable gas block and VG6 Gamma muzzle break. On top is a Vortex Viper PRS 5-25 x 50 MRAD in a Warne 20 MOA base.
I've only had it out once and it shot pretty well. Haven't tried it with the new muzzle break yet but I'm excited to test it out.

 

[alan98]

M110k1 clone. All KAC parts including dimpled barrel/bolt except for Maten receivers. Wanted to do a KAC upper/LMT lower but it shoots to well so I'm leaving it like this

 

[MERICA-LRS]

 

[Novak77]

Built this up a while ago, just been to busy to post pics.

Was going for a MK11 build. Being in CA SR25s are banned by name, so had to go with an LMT lower.

Upper is a clone correct MK11. Lower is an LMT with LMT LPK, KAC buffer tube, spring, buffer, end plate, trigger is a KAC 2 stage and paint was done by my crafty AF wife lol.

Finally got my M5 build with the new Craddock barrel shooting. The question is to paint or not to paint?

M5E1 receivers
Craddock Rrecision 20-inch Bartlein barrel
Geiselle SSA-E
VortexPST Gen II 5-25x EBR-7C
JP LMOS + JP SCS
Reloads are 178gr ELD-Ms with 40gr H4895 going 2,550 fps. Should have just enough steam to make it to 1,000 yards.

 

[MNhunter1]

DPMS GIIs, both with ARPerformance 16" fluted barrels, midlength gas, and SLR adjustable blocks. Swapped in some different furniture and MI-SSK/SLR handguards.

 

[hunter8793]

I put a new scope on my N6

 

[Disfunctional_Engineer]

Here's my build. It came in at $1015 with 2 pmags and it was a few years ago. Also note that I spent a bit more because I did 80% and you could probably shave a few bucks there and minus irons and optics I have on the gun too. It's an absolute zero frills budget build when it comes to furniture however I put the money where I thought it counted (e.g. barrel, trigger.)

The Sportical upper was kind of a mistake since I wanted to have iron sights as well but if you had a piece of glass with a large objective I could appreciate why you'd want it.

Worth noting is that you have to do your homework if you build an LR308 or AR10 style gun. The parts aren't as universal as an AR15 even within the lines. There's something like 3 heights of LR308 uppers for instance.

If I was looking for a pre built gun I'd be looking at the M&P 10 or the PA10 6.5 Creed. With reloading I'd think either could break into the sub MOA range. If you haven't yet look at Elfster's series on the PA10 6.5 CM.

[diggler1833]

New pig rig in .308.

I've got some more Grendel testing to do, and with deer season on the horizon I'll be out a lot less at night...so it'll be probably after the first of the year before I get it on some hogs.

Its got about 30 rounds down the tube. No load development, just slapped some 150gr Hornady Interlock and Sierra Pro-Hunters over 45gr TAC to see if it was good enough...shot ~ 1.2 MOA with the Hornady and 1.4 with the Sierras (5 shots at 100 yds). For a thermal hunting rifle that's good enough...I'll play with the load development more when I use up the remaining 195 Hornady Interlocks.

After many months of waiting (Australian import/export nightmare) i finally landed a Daniel Defense DD5V3 (16" .308).

Here she is fitted with a Kahles k16i, Geissele single stage flat trigger and Surefire socom brake.

 

[Night Vision Viking]

Not sure how I'm doing.

This is a JP PCS-12 born a 308 but now a 6,5 Creeeedmooore.
Conversion was HELL during COVID, and when you make silly mistakes and re-order takes half a year.
But now it shoots, thanks to a South African and a Swede.

Spuhr mount, Acro 2ndary, S&B 3-27, Ase Utra suppression.

Did some recent Cerakote to make the mount and Acro blend in.
