Hi folks, I am not new to this forum but I am new to AR’s. I have a 223 DTech upper but still need everything else to build the lower. Bolt, charging handle, stock, recoil buffer, grip and most importantly trigger. I want to use the rifle for coyotes and some squirrels. I don’t have the first clue on what brand parts to go with. Any guidance you could offer would be greatly appreciated. Just don’t want to spend a bunch of money only to find out later I bought the wrong stuff. Really curious on your thoughts about which trigger to buy. Thanks!
