hello everyone, i have a question regarding the 10/22 bolt. i just managed to punch the firing pin retaining pin (which is actually a rolled sheet of metal) out of the bolt. it took a ridiculous amount of forceful blows with a hammer to get it out. it seems that its just too large in diameter for the hole in the bolt. its hell getting in out and getting it back in. should i try and file it down some to reduce the diameter? or is that a bad idea? any input would be greatly appreciated. thx a lot guys!!
