Ok ove never built a 308 ar or an ar15 . I do however possess the skills needed to do it .what i need to know from the experienced builders is the following : compatabilty of parts with the black rain receivers . 1 . Barrels 2 lower parts 3 upper parts such as bolts/gas tube Thx in advance for the help . Im trying to price the stuff i will need

Pof looks nice but its mostly the rails . Seems a tad over priced . I definately want to use pmags so maybe ill check in building one and compare the price to a complete one since upper/lower compatibilty worries me

So building one may have reliability issues? I tinkered with the idea but that was my main concern . Dont want to have to problem solve if it is not 100% .

I can get the sig in that range . Are they any good? I figured the di was the way to go since its been around so long and with piston ar15 there's not much compatibility w parts . What's the reliability like on 308 piston models compared to di ?

What's everyone's thoughts . Pros cons . Manufactures etc . Just trying to decide between the two but I'm not paying more than 13-1700
