Currently own an AR-15. Cant legally own a handgun for a few more weeks when I turn 21 (even tho I carry one at work..)
Its being a pain in the ass atm, not always extracting the caseing before the bolt chambers another round.. Guessing its the new buffer/buffer spring with the collapsible stock. Also just ordered a magpull magazine cause the ones I have now r shit.. so maybe thatll help. Plan on getting a nice eotech for it, so wont be spending much on computer parts for a bit :P
