308 AR10 Build Info/Picture Thread

[Len5E1]

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.

Pretty. Any idea what stock that is? I built my own JP setup with .308 and wish I went 6.5... Is their turn-around really bad right now on barrel kits?

Thanks! The stock is made by Magpul (UBR), I just removed the lid and added the Picatinny for a possible monopod or bad rider.

I don't know about JP's current level. I bought the barrel 2nd hand from a friend who upgraded to a Proof Research.

The Cerakoter did a pretty nice job on it, in my opinion.

So My buddy handed me a bunch of parts and said have fun building your first AR10. Most of it is no name, The barrel measures 24 inches end to end and only says 308 win 1-10 Made in USA. The stock is MagPul. Any help would be greatly appreciated. I guess I could build a shooter and then modify later with better replacement parts. He told me these are LR 308 parts. I have my bolt gun for long range but something for 100 to 500 yds would be fun. He also gave me a bunch of random 308 ammo to go with it so I have an incentive to build a shooter. Any help is greatly appreciated.

Gonna need A LOT more than just that. And you only have the easy parts.

 

[Old Dude]

Yeah but its gonna be so much fun. My concern is not buying my next items that wont work with the barrel and guard. I think hes right and these parts are LR but with no name I am hesitant to spring for the more expensive items.

Aero M5 or M5e1 for your upper and lowers. Those are great to build on in my experiences. Not crazy expensive, but not cheap. Comfortably in the middle... and especially with the large frame AR's, there is no "mil-spec" and it can be a real logistical headache if you go with Manufacturer A for the upper, and B for the lower.

Just picked off a nickel boron Maten receiver assembly from GB last night. Almost certain to be another 6.5 CM, +1 or 2 gas-depending on barrel length. Not sure if the Bartlein carbon AR barrels will be available when I’m ready, or may just wait. Tempted to look at gain twist or possibly Proof carbon. Geissele NM, SLR hand guard, JP SCS, Superlative GB, have some spare Magpul parts lying around. Going with what I know works. Let the games begin.

 

[Old Dude]

Thanks I'll check them out.

A little PVS22 action on the 308 Noveske.

I changed out the scope to a Vortex Gen III.

LR10 6.5 18 in. ballistic barrel, Aero upper, SLR gas block, LMT trigger, LuthAR stock, Leopold 4x12 firedot reticle that I put together and my Weatherby 6.5 DU rifle of the year that I won with a 3x9 Leopold that I got sighted in this past weekend.

 

[patrol120]

Between a little bit of rathole money and a 14 day quarantine, I decided to see what I could throw together for cheap. I have an abundance of 308 ammo and components, and nothing I enjoyed shooting them through. When I saw that CDNN had some random DPMS/Remington/Bushmaster parts floating around, a plan began to formulate.

As it is, I have ordered the following;

DPMS Midnight Bronze Kit with High Rise receiver, lower, CMMG 15" rail and Bushmaster BCG
Bear Creek 20" rifle length 10 twist stainless barrel
Larue MBT2S Straight Bow trigger
Larue RAT Stock and Grip


With all the miscellaneous parts needed to finish it, and a Bushnell Nitro 2.5-10x44 FFP to top it off, I will be into the rifle for less than $1100. Its not a top notch build, and I expect to have some teething issues, but it was intended to be a project. I am not super pumped about a couple of the parts, but they were available and cheap. If it will kill steel and a few pigs, I will be happy.

 

[rpoL98]

Finished it just in time to realize I don't like Semi-Auto precision shooting. Worked up a good load with 41.3 gr H4350 and Lapua brass that shoots 1/2 MOA on new brass. Worked up another promising with 42.3gr N555 on Hornady brass that probably needs a bit of leaning out. I am about to put it up for sale - I can't justify having this when I like shooting my 308 bolt more.

sure looks like green anodized. is it? or is it cerakote? it sure is purdy.

Haven't had my .308 out for a few months because of some scope swapping between other rifles. But I was able to get a scope mounted last night and took it out this morning for a quick zero. Man, I love this thing.View attachment 7020640View attachment 7020641

Here is my contribution! Tried to make a poor man’s M110, but morphed to something better. Started life as a Larue UU Kit. Only thing still left Larue is the upper, hand guard, and bolt carrier.

20in BA 6.5C fluted barrel

This is my Armalite AR10TAC20. It's nearly stock. I just added a Wilson 2-stage trigger. Initially, I threw a Leopold 3-9 scope on it, then later wanted to try to wring a best 5-shot group out of it, so I put a Vortex Gen 2 Razor on it for a while till I got a lucky group or two. Now it has a Vortex Viper 5-25 Gen 2.

Shooter65-wrong target. More coffee?

 

[txsailor]

Hey all. I'm working on my first AR build and am searching for the right barrel. My goal is to get this thing shooting 1/2 MOA with handloads and factory match ammo and keep the barrel around $500. At that price point there are just so many options, plus is it really worth it to stretch things to $900 to get a Bartlein from Craddock or a custom from Lilja?

I'm working with an Aero M5 Upper/Lower/Parts Kit, JP SCS, JP LMOS BCG. I've probably started this all wrong and not setup a total budget, but things don't seem so expensive when you're only buying one or two things at a time.....

 

[darkfader]

So much AR10 porn in this thread. I love 'em! Here's mine, I guess it's more of a poor's AR10, but I'm super happy with it. I assembled it with all Aero Precision parts, adjustable gas block, A2 stock, Magpul bipod, and super cheap scope. Maybe one day my form1 will finally be approved and I'll switch out the muzzle device for something more QD for a can.

Welcome.

Which Charging handle is on the first two?

 

[Bigtrucknut]

Mil-spec LR308 charging handles with replacement Badger Ordnance Tactical Latches installed. About $15 each and an easy swap. The LR45 has a similar generic latch that I picked up at a gun show.

 

[whawk]

.308 DD5 has run well for the first 500rnds. Seems to be moa or better if I can hold still.
I will likely move the scope onto a 20” MWS when that shows.

 

[snarkscarbine]

M5 receivers/parts kits
Faxon 16" big gunner .308
SLR Helix 13.5"
Faxon BCG (until my Lantac E-Bcg arrives)
Superlative gb
MBT-2s
Tubb spring + H3

Runs smooth.

 

[RUTGERS95]

love this thread

decided to build another 308 so have all aero parts except using an A1 stock and bought the centurion cmr 308 rail. Will post pics after this weekend as I put it together when I get some time.

 

[ManOfSteel]

nothing special but damn does it work. 18”Aero build with FailZero BCG, JP SCS, PA Raptor 1-6, Larue MBT, Magpul furniture and a Socom brake. Did a 50yd zero and I’m calling it good for what it is until I have time to shoot it past the LabRadar and get to a longer range than the 100 I have near me.

Upper, lower, handguard: Matrix Arms builder set
Barrel: Nordic Components 16" 308

I have probably 6 boxes of ammo through it. Seems to really like 140gn SMKs. I cant get it to shoot worth a shit with the 140gn S&B FMJ even at 100yds. Im sure I have something to do with it. Anyone else have any luck with these Faxon barrels?

@HornDog87

I appreciate it. I have no idea. I found a picture of a rifle that I liked on Tier 1 Defenses page out of New Jersey, and they replicated it. They may know. It was completed mid 2015 and I think still on their Instagram page. Good luck.

 

[HornDog87]

It looks pretty damn close to duracoats tactical od green either way man it looks great and I'm copying the color scheme.
