Hmm the shroud did not fly off the back of the bolt like our "Expert GAS Handler" said it would. Anxiously awaiting his/her explanation of why it did not, perhapshe/she does not realize it but escaping gas whether it comes thru a .050 hole or a 3/8" hole is still bad for the shooter. He/She might also realize that the design of the bolt is of paramount importance ie how much the rear of the cartridge case is exposed.
Appears to be a place on either side of the cocking piece of the RAR where gas could fly out of .
