my buddy has an sar-1 with his second rsa trigger.The first one the disconnector just sheared off. They were cool and totally replaced it quickly.However we went to the range today(indoor-no rapid fire)and shot the sar-1 with the new rsa trigger.Well it double tapped twice when my friend shot it, I thought he was just shooting too agressive.So he let me shoot it, the first mag went smooth it shot real nice.Popped in the second mag and was half way through it then braaaaaapppp! the damn thing went f/a 5 shots+ until I let go, otherwise I could of cleared the whole mag. Scared the livimg shit out of me! We took the whole fcg out, no visible damage. The staff at the range were a little razzled and demanded to see the internals and we explained what happened and they were appalled.RSA is a great company I NEVER ever heard this happen to anyone on the boards.I just wanted to give everybody heads up because that could of turned into a pretty deadly situation for newbie or someone who has little expirence with semiauto's.Just so you no Im not bashing RSA I think they make awesome products, hell not every ferrari that rolls off the line is gone to perfect, but this is an expirence that you must all be aware of. thank you
