I decided to trade a Colt AR-15 Magpul edition for a scoped, with BUIS 556 Swat rifle. I took the 556 apart per the manual and cleaned it. It is practically new in box no wear to speak of. I went to the range and it will only fire one round art a time. I manually cycled the bolt through 30 rounds to zero the scope (Redfield Revenge) 2x7, which it did zero. I almost ran out of windage but i hit a 6 in plate at 100 a printed center mass at 50. yrds. But it will not cycle brass factory or powder coated steel case ammo. I must manually cycle the bolt every time. I made sure I assembled the gas system as the manual stated. Is it possible I closed the gas port all the way and this is the reason it will not fire simi auto? Or is this 556 a piece of crap?. I hope I did not get a lemon. I understand thier customer service is not very good. Any suggestions before I send it to Sig with a nasty note? Thank you for the help. I used proven magpul M16/M4 magazines.
