Build or Buy AR-10 Platform?

[sava]

Hey guys,

Looking for some advice regarding the an AR chambered in 308.

I have built up a few AR15 rifles from stripped lowers and multiple 80% builds, so I am no stranger to the AR platform.

I have a vice block and all the necessary tools for building/disassembling AR15's, but have absolutely ZERO experience with the AR10 rifles.

I am planning on getting myself into the 308 game, and would like to know if the AR10 platform is as easy to build/customize as the AR15 variant.

I have heard that the AR10 can be very picky about the components used and is more difficult to work on than its little brother. Is there any truth to this?

I'm trying to decide if building or buying is a better alternative. I would much rather build my rifle, but not if it will result in an unreliable or malfunction prone firearm.

What say the calguns gurus?

The ar10 has about as much to do with an ar15 as a m14 has to do with a mini14. The parts look alike but they are not the same.

what do you plan on doing withe this gun?

Well there you go, my lack of knowledge is already clearly evident.

The gun will be used for further developing my long distance shooting knowledge. Up until this point I've used my 22LR trainer and 556 rifles to learn how distance affects shooting.

I've become quite proficient with my 22 rifle and can place rounds on target out to 400 yards. Granted the 22 isn't made for distance shooting, I've learned quite a bit by shooting the rifle beyond 200 yards.

So I feel the 308 is the next step for me.

I built my lr308. I've always felt like building the platform is the greatest way of learning it. Trial and error. My opinion.

For distance I would recommend that you go with a bolt gun. With a standard gas system on an AR 10 you're limited to about 26 and a half grains of varget behind a hundred 68 grain projectile. You're also limited on the OL that your magazine will accept.

My experience with building an AR in 308 is that the rifle isn't nearly as popular as AR-15's and this the average parts available are expensive and at risk of being of much poorer quality as a result of an unsaturated market.

The parts are virtually identical to an AR-15 with the exception of them being quite a bit larger, but if you know your way around a 15, then you should find yourself perfectly at home with breaking down and/or building a 10.

If I were interested in owning another AR in 308 though (I sold mine and replaced it with an M1A), then I wouldn't even think twice about buying a complete build from a quality manufacturer due to what I experienced as massive deviation in quality of parts when they don't all come from the same factory.

Price wise, a bolt gun would run the same, more, or less than a SA AR10?

Way less.

There are plenty of good parts available for 308 AR's though.

Fulton armory anf jp sell quality items for the 10. I had only done minor gunsmithish work and such on my one ar-15 and i built my lr-308 from the ground up in just a couple hours. Its not hard whatsoever IF you buy quality parts from the get go. And as for COL i have a wilson adjustable gas block and i just shut it off and run it as a bolt gun with the fulton side cocking upper.with quality pqrts mine is less than 1/2 moa at 100 and sub moa at 1k and that is in semi auto and gas off

Ar10's are expensive and heavy. A bolt gun does sound like a good option for you for your intended purpose.

Right now good AR10 parts are harder to find than usual. If you decide to go the AR10 route a complete rifle will likely be easier to come by.

While Clint at Fulton is not a friend of Californian, his shop makes excellent DPMS pattern Ar308 rifles. Unless he has changed his ways, he will sell you an upper without issues, but you may have to find the lower somewhere else.

They sell cali lowers too. I agree they are heavy but can be built light, someone on 308ar got one down to 7lbs sans ammo. A bolt gun would be much cheaper route. But i suggest the glass as being the most important piece of whatever you choose to do. As with 15s they are very versitile and depending on what your want to do they can be configured to what you want easily. A happy medium would be an 18 or 20 inch med or heavy contour.

And as farr as being pickey on components, as long as you know what fits youre platform (ar10, dpms,lar-8,etc) most things work just fine.

A Remington 700 would leave you a lot more money for primers powder bullets
