Until... I screwed it back up only to discover that it got TERRIBLE ranges of about 8-10m, or 25-30ft.
The only problem I see is that when I was taking out the AR with some needle nose pliers, I did a pretty scrappy job of keeping the inside tidy - there are a few small dents and stuff around the inside of the tube. Also, when I try to prime it back, the bolt stops about 0.5cm from the actual back position, and resists being primed forward at the same point every time.
Someone please tell me what is wrong with my longshot?
