Help Building an AR in 308

[l730dc]

50 beowolf is about the largest for the AR15 platform .

Lol.. I should of been more specific.. and I should of known someone would of said beowulf.. I kindof meant a farther flying round.. something for distance .. more aerodynamic .. ill probably have to go 300...

These ars are money pits man.. lol..

What's everyone's opinion on the AR-10 as a battle rifle ?

Generally piss poor.

They make great DMR and spotter weapons - but most of them - when pushed hard - are not as reliable as an AR-15. That includes those expensive KAC models.

The LaRue and Noveske seem to the exceptions, but there isn't enough data IMHO..

YMMV

The 6.5 Grendel is what you seek. High BC bullets with a reasonable velocity (especially if you're looking at a 20-24" barrel). You can load it with fire-formed 7.62x39 cases.

ETA: the .300 Blackout is a piss poor option for a 'farther flying round'. What it is good at is being suppressed with a 9mm suppressor, and with some bullets having better terminal performance out to 200y compared to 5.56. But 5.56 soundly trumps it for 'long range' accuracy.

I believe the WSSM rounds will fit in the AR15 length magazine.

I wonder if the bolt could with stand that kind of pressure....

They have made them already. I believe they use a bolt head and extension that have the AR10 size locking lugs.

Yep - Olympic Arms makes WSSM uppers for ARs. You lose 'standard capacity'.

It's not unlike the .30 RAR

I wish I knew of half the crap you guys are talking about...

Guess it's time to do some research!

Oh, and just checked with the FFL dealer I go through: 308 lowers are regulated, complete rifles are not.

Not regulated by law but some dealers treat them as regulated.

If you can find one, take a look at the LE901.

 

[armed ferret]

many companies make bolt-action single-shot and magazine-fed .50BMG uppers for ar-15's.

that work for distance for ya?

I think the biggest downfall to the ar10 is it's weight. dpms makes a lightweight upper receiver and lightweight barrels are rare but available. Combine that with a lightweight carrier handguard and stock and the rifle should be well under 8 pounds. I'm trying it now will post when I figure out the completed weight.

308 lower.

You can build up from stripped. The bolt catch threaded bolt catch pin, pivot pin, takedown pin are specific to the dpms lower. rest of parts you can use AR lower parts. buffer tube buffers can be a combination of AR carbine tube with short 308 carbine buffer; vltor A5 or AR10 buffer tube with standard ar15 carbine buffer or A1/A2 fixed stock buffer tubes with 308 sized rifle lenght buffers
