What barrel is that? Is that the Troy rail made of Carbon Fiber?
It's a Seekins SP10 barrel and brake... I think they use Rock Creek blanks from what I understand. It's 1:11.25 twist with intermediate gas, Seekins adjustable gas block.

It is the Troy carbon fiber free float. I was nervous about its strength before buying it but it's turned out to be just as tough and rigid as an aluminum handguard. I bought the aluminum version too for a second build, Troy also. I'm so happy with this carbon fiber one I'm pondering selling the aluminum one to get another CF like the one pictured...

Thanks for the information. Did you do anything special when you cut it?

New to the forum and LR. Here's my first (cheap) gas build.

- PSA Lower
- OdinWorks upper 24" 6.5 Creedmoor (1 MOA barrel)
- Griffin Explorr (Until my TBAC comes in). Took 60 days to get the griffin out of jail!
- UTG Bipod
- Sightron S-TAC Duplex :( riflescope
- Timney trigger on it's way.

I like how light and simple the rail is on the Odin.

Looks great, I just got the 22 inch odin 6.5cm upper. Does it have the +2 gas tube?

How does the utg bipod hold up?

I put this AR10 in 6.5 creedmoor together several weeks ago. The build is as follows:

Aero Precision M5E1 builder set. I had the set cerakoted OD green...turned out great, IMHO.
Dracos 22" barrel in 6.5 creedmoor
DT Brake (fits my suppressor)
Rubber City Armory Titanium BCG ( the bolt isn't Ti, just the carrier)
JP Silent Capture Spring
Triggertech AR Diamond trigger
Ergo Grip Tactical deluxe grip
POF Charging handle
Magpul PRS stock
ZCO 427 scope
ARC mount (20moa)

AR10.jpg

AR1065.jpg

Of the variety of ammo I've tried so far it really likes the Hornady American Gunner ammo, and the 147 grain Hornady match ammo. I really wanted it to like the Berger ammo for the lapua brass (for reloading), but that ammo shot the worst of everything I've tested thus far.

my 6.5CM upper build. Lower is just my workhorse/mule that I swap around to various uppers.

Aero M5 upper
Faxon 24" barrel, rifle-gas
Brownells HP nitride BCG
SLR Solo Lite 16" KM
SLR Sentry-7 adj GB
Armalite AR-10 rifle gas tube, painted flat black
VG6 65 Gamma brake, PA shims
dust cover by CustomARDustCovers
Rainier Avalanche charging handle
Vortex PST Gen I 6-24x FFP MRAD, SV-2 throwlever
AD Recon-S scope mount

Aero M5 lower, Geissele HS-NM, B5 Bravo stock, POF carbine buffer tube, Norgon ambi, KNS Gen G pins, KAK 5.3oz 2.5" buffer, Slash/Heavy-Buffer 308 carbine spring, CPD 20rd mag.

shot it this past weekend, after dialing in the gas block for last-round bolt-hold-open, no feeding issues, perfect functioning with factory ammo: Federal 140gr soft-point and AE 120gr OTM. Very pleased with the accuracy, but was only plinking at 600yd and 800yd steel silhouettes, the fun stuff. Follow-up shots can be done quickly, before the preceding round hits at those distances, but then you don't get to hear the gratifying "ting" on the steel.






Armalite gas tube extending into upper receiver. please ignore the liberal slathering of grease, just a mock-up assembly to check fit. Gas tube does not bottom out in carrier gas key.

Any muzzle break reccomendations for a Ruger SR762?
if the muzzle of your barrel is threaded 5/8-24, then you can use any of the common or popular AR-10 muzzle devices. for anything over 16" barrel length, I like the Precision Armament M4-72, although TTAG says there's now a new King Of The Brakes. The M4-72 is certainly an effective brake, no denying that.
JMHO, YMMV.

Love the color man. I too have an LMT-MWS but it came in factory burned bronze which I'm reluctant to blast off. What was your hardener mix on it? Looks satin finish which I like. If I may ask, is that the 18SS barrel which you cut down or is it a 16? Did Marvin Pitts do the work on that barrel? Mine came with the 16CL barrel and I have a 18SS which I might send for work.

Great looking beastie.

-Ballistic advantage ss 22" 6.5cm
-JL Billet 308/AR10 15" Angle Cut M-Lok Handguard Low Profile
-aero precision black nitrided bcg
-schuller brake
-superlative arms adj clamp on GB

-Burris xtr-II 5-25×50

Showing some promise with Hornady eld-x 140gn factory ammo (5 shots at 106 yds while prone on top of 16"of snow and this monkey behind it)
This is the kind of pic I like. Guys just showing of their toys is ok, but at least show us what she can do for the money in the parts!

Not really a build but lightly modded POF Edge 308 pistol turned SBR because I wanted to a piston setup cause of being left handed. But it’s a 12.5 308 with a Q thunder Chicken on the end with a Atibal X 1-10 Scope with larue mount and i did swap out the trigger for a trigger tech.DDE816A5-2A41-494B-AA49-95F89C4507FD.jpegDDE816A5-2A41-494B-AA49-95F89C4507FD.jpeg

    Awesome build. I have been thinking of something very similar. Have you ever weighed it?

    @padom @bigjake83 have either yall tried out any a the new "Gen II" type lightweight/small frame .308 AR uppers/lowers? Eg the DPMS, POF, Remington, etc..? Or any plans to?
    i think the proprietary nature is the biggest deterrent. whatever config you buy, you're kinda locked into it. although the "lack of standardization" of the AR-308 platform causes a lot of issues, it's nowhere near as restrictive as what you would get with a one-brand proprietary platform.

    I do see that Rainier does offer barrels for the DPMS Gen II, so maybe 5-10 years from now...

    Somewhat off topic, does anyone know what country this sniper is from/serves, the dude in the still-frame of the video and also shown in the very beginning of the vid, resting his HK417 on a blue barrel, apparently in the standing position touching a round off..?? Just curious, I dont see any patches whatsoever.. I've heard Delta has 417's in their inventory to go along with their 416's..? Maybe hes a D-boy??? What yall think? @MSTN ??

    Here's my .308 I've been working on and finally close to finishing. Getting ready to actually go test her at the range to see that she actually shoots.

    Mega Maten receiver set
    Mega 20" rifle gas barrel
    SLR adjustable gas block
    SLR Solo Rail
    AAC Brake Out 2.0
    Aero NiB BCG
    A5SR RE
    Magpul ACS stock

    Parts on order:
    atlas bipod and unipod with magpul adaptor

    Still need to order:
    Giessele SSA-E
    Scope and mount
    -between NF and S&B. Was set on a 4-16x42 but the amount of 5-25x56 I see here has me reconsidering.
    -mount wise I believe it will be a Spuhr mount just need to figure out what MOA base the scope I end up with needs.

    - Current scope and rings were borrowed from friend for photo and use while test firing.

    Under consideration:
    Looking into suppressor options. At the moment I'm leaning towards a TBAC Ultra 9 with CB mount.

    Nice. Didnt Zev take over Mega? Also, didn't Mega used to use Rock Creek barrels back in the day, or was that POF? Anyway, nice rifle. You plan on doing any hunting w/ her?

    Very cool @shax2lex - have you considered getting hold of some clip on NV sights, or NVG's of some sort? Night time hog hunting is probably the pinnacle of fun with a firearm hah.. nice build anyhow tho. What projo's you plan on using for hogs? Have you tried the Barnes LRX's by any chance?

    A repeat build of an ultra lightweight 16" .308. 7 LB 2 OZ and sub-MOA capable. Battle Arms Development BAD762 billet receiver set with 15" BAD 762 RigidRail. Proof Research carbine fiber wrapped barrel with optimum intermediate length gas system. JP LMOS bolt carrier group. SLR adjustable gas block. TriggerTech 3.5 LB straight trigger. Geissele 7.62 Super Charging Handle. Every V Seven titanium parts made for the big block guns, to include the excellent 7.62 Furion muzzle brake. Fantastic plastic by Magpul.

    The recoil pulse with this thing is amazingly low with 175 grain match ammo. But, this gun is a steady diet of Mk 319 130 grain Barnes TSX destruction. This high pressure load produces LOTS of gas at the muzzle and reduces the recoil to just about nothing... But, is it ever LOUD!!! This ammo produces a simply unbelievable 2830 FPS in this 16" barrel. It runns reliably with the adjustable gas block only half open.

    10 LB 2 OZ with full 20-RD magazine and Kahles K16i on Spuhr SP-3026 mount.

    Hello folks, first post! Just finished my light weight 308 build. Coming in right at 6 lbs before scope.

    Aero M5 Upper/Lower
    Juggernaut Tactical 18" Barrel
    Smoke Composites Handgaurd
    Smoke Composites Stock
    RPR Hyrbid Brake (because I had it laying around)
    Seekins low profile adjustable gas block
    Brownells (Toolcraft) titanium BCG
    Taccom ultra light buffer (only running one piece of the two piece 556 set so my 308 BCG doesn't bottom out in the carbine buffer)

    Runs like a champ, fed it some cheap reloads I had laying around to break the barrel in and get the gas block set. Will be working some loads up this weekend!
