Hello ,i am hoping someone on here can help me out of this embarrassing situation. Long story short my 81 year old dad has decided he misses shooting and has just purchased a 99 ,he asked me to drop a tin bum kit in which I have just done . All went well until after putting it all back together I found a small steel tube size wise it’s 10 mm length 6mm across 4mm inside . I will try to put up a picture. I can’t recollect seeing it when I stripped the gun the only thing I can think is that it’s dropped out of the trigger unit .
I have cocked the gun then decocked it and everything seemed to work as it should do any suggestions will be gratefully received .
Duncan
