Im bored and have been wanting to do a 308 build for a while, but just hasn't been the best year..Anyways i want guys that have and are building them to chime in....Cause when the dust settles,i will SLOWLY gather parts..lol

What lowers,uppers should i be looking at beside the obvious ones, What barrel and how is it doing?

What im thinking is a 16-18" build, and not a heavy mofo either, would like to keep it light, not super light but not a heavy bench gun either, and also to shoot well..Too much?...

Throw out your builds and how their shooting and deals on parts and how much there weighing in at, as that is something im looking at.

Pics are always good to....[:D]

I've got a buddy that big into the AR10 stuff and keeps trying to get me to build one. It's tempting, but i've got a Springfield 16" SOCOM high on my .308 want list

Mega Maten's are by far the most versatile receiver sets for a .308 build. The last one I built I used a 20" Rainer Arms Ultra match barrel with a JP BCG and it is extremely accurate. I have shot multiple 1/2" groups over 100 yds. with that rifle. I originally used a CMT trigger but had issues with hard primers ignighting in the mil surp ammo. Switched to my standard Geissele trigger and have not had an issue since. I am using a very heavy rifle length buffer with a standard DPMS rifle length spring. Recoil is barely more than 5.56 weapon. On a few other builds I have used the shorty buffer with a AR15 carbine buffer tube and spring and was not happy with how the they ran. Honestly all my AR10 builds disappoint me after running my SCAR 17.

I have a Mega .308 pistol build in the pile with about 10 other builds. I have hunted with a single shot .35 Remington pistol for years so the decreased recoil and multiple rounds will be nice.

I am stuck between a Rainier Arms (http://www.rainierarms.com/rainier-arms-ultramatch-billet-upper-ambi-lower-combo-set-308) receiver set or a SI-Defense (http://si-defense.com/shop/ar308-ar10-receivers/308-ambi-receiver-set/) receiver set.

Close up of the receiver & CMT bolt. I sent the upper directly to CMT and they headspaced the bolt to the barrel for us.

Forgot to add: buddy told me he's shot 1" groups at 200 yards with the gun. He left the day after Christmas to go to Alaska to duck hunt and took the CMT with him to shoot caribou. Haven't heard any results yet.

Regarding the barrel length...accuracy isn't really the issue provided you start with a quality barrel; the only real difference will be a slight decrease in velocity going from 18" to 16". A good barrel (I have two Rainier's and will stick with them) and good ammo (I hand load and test A TON) makes a world of difference. Are you going to suppress it? If so, I'd run the 16" gun just to keep the length down. 18" if not, but that's a personal choice.

Ya that RA set is my #1 pick but , for me sadly i always have to play the budget card, to a point...Ill have to look up that SI set

I am really thinking 16" , maybe 18" and yes this build i would like to go all the way and throw a can on it. i also handload , and enjoy that so no worries there at the moment..

Just getting a feel for what you guys a re building, whats shooting good, and for me a big thing is weight for this build....

Ill take a look at that link later..Thanks

For the moment theres only a few forged sets that are available, and the AERO set is looking like the best bang for the buck, but then again this is why i asked this question/thread...

Wasn't me...I never win anything. Check that; I won $2.00 on $14.00 worth of lottery tickets the other day...[BD]

The gun I built for my buddy has a 20" Rainier Select Series barrel with the polygonal rifling. It's pretty heavy overall and definitely muzzle heavy, but not a big deal for shooting off the bipod.

I know I want to make a .308 also. I'm still trying to decide though if I will do a .300 blackout carbine or a .308 as the next one. Both are on the list and I can only do one at a time. The 7.62x39 is almost finished - needs 4 more parts. Then I'll have to make the choice. I have another choice to make too. I've been wanting to try my hands at starting from an 80% lower receiver. It will cost me more than just buying a lower receiver but, there is value to doing the work myself. I'm thinking I will build the .308 next then the .300 blackout using an 80% lower receiver. The 300 can be the next winter project. I don't have the machine shop tools for that, but a customer and friend of mine 6 miles up the valley does and he's already told me that I can use his tools (he likes guns too [:)] )

I like working with metal and know that I would very much enjoy spending the time to fine finish an 80% lower receiver. I haven't decided where I will buy one from yet though.

On a side note, I just got a news message from Weapon Outfitters about a new upper receiver that uses a new design with it's own gas tube that get's lined up with the upper receiver. It has an adjustable gas port in the upper receiver to vent off excess gasses. This has been specifically designed apparently for switching from using a suppressor and not using a suppressor. It's an interesting and innovative idea. I want to use that upper receiver for the .300 Blackout design that I have in mind. What does hurt though is that I'd like to make that as an SBR with a suppressor. Granted I'd have to pay the tax stamp for the suppressor, but I don't want to have pay a second tax stamp for the SBR. I wonder.. since suppressors are generally around 5" long, if one is permanently attached to a barrel would that make the rifle just be a rifle since the barrel and muzzle device would be longer than 16"?

WAR upper? I purchased one from
WO for a 300 Blk build myself, but don't see a need with that round for an adj GB, so it has been moved to my 10.5 5.56 build.

It really depends on the lower you choose. For example, I have a Maten lower and it accepted standard DPMS LPK parts EXCEPT the bolt release. A non-DPMS release worked fine. The beauty of the Maten is that it comes with a lot of the parts already attached and, as someone mentioned, is compatible with most AR-15 parts.

The RE is a little weird. There's a guy who I found through Google (by way of ARF I think) that sells a .308 buffer that works in an AR-15 RE. I've had zero problems with mine both suppressed and unsuppressed on my SR-25. I actually prefer my Maten (and it's SSA-E) to the KAC lower.

You will need a .308 bolt catch and take down pins.

You can use an AR-15 Receiver extension, if you get a .308 buffer. I've used that combo without issues.

Oops...error on my previous post... The Maten doesn't work with a DPMS .308 bolt catch, but does with an AR-15 one. Again, one of the oddities (but coolness) of the design.

No clue, except heavy. I'd say the one for my buddy is 11 lbs. or better with everything on it.

308 specific parts besides the obvious upper/lower.barrel/bcg

CMT Billet receiver set & BCG, the Rainier Select barrel, 20", with the JP Enterprises muzzle brake. Rifle length gas system with a Yankee Hill lo pro gas block & tube.


What about Buffer tube and buffer?
DPMS set from Brownell's with tube, spring, buffer, castle nut, and end plate. Magpul MOE stock.

I ordered the CMMG kit from Brownell's, and threw the grip and hammer & trigger in the parts drawer. If I was doing it again, I'd order the small parts from some place like Damage Industries or White Oak Armament, and buy the grip and FCG, (like the Timney we used or a CMC or Geissele or whatever), separately. The takedown and pivot pins, as well as bolt catch are different than AR15. On the CMT set, you have to shorten one of the detent springs, (for the takedown pin) per their included instructions.

Check-308 catch and takedown/pivot pins.


the buffer thing ( as i keep researching/reading) seems to go 2 ways use a std ar15 buffer and a 308 buffer, then some say no use a dedicated 308 tube and buffer, My question is there a physical difference, like in length ?

Lol...I thought you might say that...i have and have some select barrels and they have shot just fine...

Just curious what others to look for, I see mega makes a 16" 308 barrel. and i have the baby 556 mega barrel...

U B welcome. I was talking to one of the specialists at Brownell's last night via their chat function, because I'm looking at the Magpul PRS for a project. I have an A2 stock/tube/rifle buffer and spring set up on the parts shelf. According to him, I would need a different, heavier spring and a different buffer for .308, but the tube is the same for .308 or .223/5.56. He said the same applied to the carbine set up as well. Makes sense to me that the spring and buffer should be stouter to handle the additional punishment, and I know from browsing that JP Enterprises makes different springs for the two different calibers.

Like Tact says, I think you're talking about an Innovative Arms (made in SC about 45 mins from me) upper receiver.

I've had one for about two years now and its worth every penny. I want a second one for my SPR build.

Tact, the WAR is different than an adjustable gas block. The WAR allows the gas tube to remain fully pressurized and gives the rifle a much softer feel. My 16" middy barely has any recoil ad

I know as far as barrels go, the medium contour 16 inch version of the Rainier Select barrel is only about 1.5-2 ounces lighter than the full version.

I know where I will really would save weight on mine (even though it's 5.56) is the barrel/rail combo, the optic, and the stock (go with something like the Magpul STR instead of the PRS or UBR for example).

You know me..im a cheap ass slowly coming around..lol..

So without looking them up, i can remember some numbers off the top of my head

-PSA set
-Aero precison
-CMT
-RA billet set

First 2 for a set mid $200's plus transfer fee and tax, and really not even gonna consider psa for my own reasons...so aero is kinda the winner.............then it jumps up quick like 4 something for CMT and almost 6 bills for the RA set, Which is my favorite of them all, but i just wont be able to swing it..Unless i win some kick ass 308 cerakoted set like some else i know..lol......but that wont happen gingers dont win shit...[bash]....lol


Now if Mega Arms offered a 308 forged set for around the same price as the aero, then hell yes...

Ha good luck getting anything from Aero anytime soon. I ordered two "overstocked" on-sale receiver sets on Christmas Eve and when I called today was told ATLEAST 3 weeks, probably more. Putting me in a bind because I have both pistol builds finished sans the receivers

Yeah, I don't see a forged Mega .308 set happening any lifetime soon.

We keep asking them about laser engraved Mega BCG's, I think they will eventually do that. They have some other projects they're working on to bring to market.

Also, Did Aero say they only like proprietary take down pins? This is the first Iv'e heard of it.

Ya i would of held out for a mega 308 forged set...did see that spikes is making a dueling penis 308 lower now...lol..

The pin thing is not something im up to par on, i hear you can use other pins, but they dont fit good and are short??..again i am repeating crap i have heard and seen pics of....just heard they had a huge batch of bad pins go out and people showing pics of them and its not isolated, many . many and aero has said they are getting in new , good pins soon, yet they have them on their site right now for sale.........:confused:


I had a big reply typed up, but cut it down to G rated, i have a few reserve thoughts on aero, and this is not the thread for it.


Anyways...Back on topic..whos running a aero 308 set? built up recently? What pins ? any problems?

Regarding the takedown and pivot pins, Aero Precision's .308 lower receivers must be a little wider than other DPMS pattern receivers.
From their lower parts kit description:

"Our custom takedown and pivot pins are made to work with our M5 lower. They will work with DPMS-pattern lowers as well but will stick out further."

I need a new battery for my digital calipers. I'll measure my receiver as soon as I get a new battery.

Thanks they are a smudge wider right there, i have seen the pics, the pins stick in , instead of out so u need to use a punch or bullet to push it/ get it started out..


Also confused on what buffer tube setup to use..99% sure when the time comes i will be using a adjustable stock.

If you are going with a carbine set up, the actual buffer tube/receiver extension, (whichever you prefer to call it), is the same. The difference is in the spring and buffer itself, which I learned when ordering the parts. This is the set up I put on my buddy's .308 build:

You can use a .308 Buffer with an AR15 Extension. Have several of these setup, and they function and cycle just fine.

Mustang,

I would save your pennies and get one of the Rainier Arms 16" or 18" RA308 rifles. They are priced really right for the components you get. I think you would be hard pressed to build an AR-10 patterned rifle for less than $2600. I have done a couple Mega MATEN builds, own a couple SR-25's and owned the 16" RA308, which I only sold to fund one of the SR-25's. I never shot the RA308 past 200 yards, but it was Sub-MOA all day with factory 168gr PPU ammo. I shot better with it than I do my SR-25. I regret the sale and will own another.

CMC Trigger, RA Ultramatch Barrel and Ambi Lower/Upper set...all top-line parts for $1000 less than comparable LMT , POF and LWRC offerings.

Roll in to RA and finger the RA308 compared to the LMT and REPR. It's a no-brainer.
