Hey still new here want to start a new project. Been dying to build a 308 AR. Still up in air on what to use. Lowers , something milled out of solid stock not forged,A2 upper, about 20 barrel heavy but threaded on end, collapsible stock, free float barrel. But I'll take any idea's you got. i have tried to read as much as i can but just not finding info here. I have done some .223 ar's and i really like the hydraulic buffers and was thinking about one for this build too.
