Hey guys 

I need some help I’m putting together my first .308 build using aero precision 18incj upper and lower. I plan on using the magpul ubr stock but I’m lost with what buffer and spring to use and help would greatly be appreciated.

thanks 

The receiver extension is incorporated into that stock, so you need the UBR 2 (UBR Gen 2, ) to run an effective recoil system on a .308 AR. 

Then, you need the Armalite EA1095 recoil spring, and a 3.250" long H3 buffer.  That's either any old AR15 H3 buffer, OR the Armalite AR-10 Carbine Buffer - those are the same exact thing.

Ask questions about the info, if you want, but that info is solid.

Lastly - you just received Free Information.  Do what Doc said, and hit the intro section, and tell us about yourself.  Pay for that information, by doing that.
