recently i picked up a Century Arms Ultra 87... an imitation of the Remington 870. Well i had stripped it just to get to know the inner mechanisms. i followed the instructions, took off the ed of the mag. tube, off the barrel, then popped out the 2 pins that hold in the trigger mechanisms, and pulled the trigger out. when i was satisfied, i put the trigger back in, but accidentally pulled the trigger. i felt something pass over my hand, and saw a light curtain move a bit. so i pulled the trigger back out, looked it over, and saw nothing missing. confident that i hadn't over looked something, i put it back in the gun. thats when i noticed what was missing.
i don't know the proper name for the part, but its what the firing pin is in. i guess it would be called the bolt. but where that normally sits, on the back was a piece of metal that stuck out. similar to the piece that holds rounds in the mag tube.
i put everything back together and lightly went over functions (used snap caps). the bolt locks into the barrel just fine, and everything ejected as it normally did. i wanted to see what other people thought before i went shooting with it. from what it looks like to me, all that piece did was help eject cartridges.
and before you say it. i know it was stupid to have my hand near the trigger. i know never touch the trigger till your ready to fire, but something about having no barrel on it seemed to... i guess negate the feeling of the need for that rule. or something like that.
any help would be much appreciated.
