AR-10 info help

[DirtySCREW]

I'm asking for a friend as well as myself. What do I need to know on building an AR10? Is it any different than building an AR 15?
What is the going price for AR10 stripped lowers? 80% lowers?

I would assume it's the same as building a 15. Any special tools needed? 20" barrel the "norm"?

Sorry for these probably basic questions...but when you don't know....you don't know. I can't very well advise him if I'm in the dark too...lol

main thing to know is it's cheaper to buy a complete lower, or an OEM rifle

If you've never built one, yes it's different than an AR15. The recievers, BCG, magazine, buffer are all different (bigger) and the rails don't always interchange.
DPMS and Armalite are different pattern rifle specs, and within the DPMS there's a 'high and low' version.

My suggestion is either to buy an OEM rifle and add furniture, or buy a compatible upper and lower and pin them together.

As far as barrel lengths go, you can go 20", which will shoot milspec XM80 ammo around 2800fps. I like my 18" middy but if I rebarrel I'm going to a lightweight 16"

With the big platform stuff you have DPMS Gen I and Gen II patterns these are the LR-308s and then the AR-10 pattern which is Armalight.

DPMS Gen I stuff is where most of the parts are at. I am in the middle of a 358win build and have to pay attention to everything from upper, bcg to barrel, barrel nut and hand guards.

Word of advice, buy your lower and upper matched already. I went with 5D tactical for my upper and lower so I would have any issues

Honestly if I had the money I would have bought palmettos pa10 and have it rebarrrled To 358win. But I am setup for 80% lowers so why not.

You will need a different armors tool for the barrel nut from what I have read
