Board:
Yesterday I blew up my sp1
After firing several shots, I pulled the trigger and the dreaded click was heard. I pulled the charging handle to the rear to eject and feed, and got a double feed. Pulled the charging handle to the rear and locked the bolt to the rear. Dropped the mag and the double fed round. Looked inside and there was a round in the chamber.
DON'T DO THE REST OF THIS DRILL.
I then pulled back on the charging handle and allowed it to go about half way to the chamber then released it. BANG.........
The slam fire split the upper reciever down the centerline below the carrying handle, blew the shell casing half way out the chamber disallowing the bolt to go all the way forward. Also the bolt will not go completely to the rear and I haven't figgered that out yet. Ruined the gun, and I got some few little powderburns and abrasions.
Bottom line is: Don't let the bolt slam forward on an AR, or M1A, style rifle while there is a round in the chamber. It probably won't slamfire, but if it does, you won't like it.
I had heard of this happening, but had done this drill a couple of times during my shooting years. Over 40 years shooting. Nothing had happened before, so I didn't think much of it.
Learn from the errors of others bretheren.
Yours in shooting,
