safe queens, huh? some of the people around here like Bushy even less than they like DPMS. I personally like my DPMS product. There are a lot of detractors but...
Colts and FNs arent perfect either...I know, I shoot them at work all the time. You feed them enough blanks, dont lube them right, do anything else wrong, they are fallable.
Khar pistols are usually great, my buddy/fmr TL has one with thousands of rounds and zero malfunctions. mine is back at the factory after less than 100 rounds because the trigger doesnt reset properly.
Some people around here have Bushys with no problems. Some people had bushys with nothing but problems. Blackwater apparently uses a lot of Bushys with, IIRC from what I read a year ago, mixed results.
The only two AR manufacturers Ive seen in action that ive never seen fail my self are DPMS and Guide Lamp Division General Motors (and the last two GM products Ive owned have had enough issues that I will never buy one again, go figure)
Remember that it is one sample of a manufacturer of mechanical devices. Whatever your results may be. But whatever they are, please, do tell.
