billm67 Posted April 28, 2022 Share Posted April 28, 2022 I have a Foxtrot Mike 9mm BCG. Apparently the CMMG and Wilson firing pins don't fit their BCG. They will sell me a "Maintenance Kit" for 20 bucks. I want to use this rifle for steel challenge and other matches and want to have reliability and ease of getting parts. Am I better off to replace the bolt with one that uses more "Standard" pins and springs? Or should I stick it out and hope for the best? Also, does anyone have a list of which bolt carriers groups will accept Wilson, or CMMG or PSA pins/spring? Link to comment
Dirty_J Posted April 28, 2022 Share Posted April 28, 2022 Never heard that one before. Every 9mm BCG (except for JP) that I’ve touched all used a compatible firing pin. Link to comment
WildPete Posted April 28, 2022 Share Posted April 28, 2022 I didn't know this about the Foxtrot Mike BCG until I happened to get light primer strikes. Went to put in a DaVinci firing pin and spring. The pin fit but the spring wouldn't. Had to use the Foxtrot Mike spring. Swapping firing pins seemed to cure my light primer strikes. Link to comment
Scrounger Posted August 30, 2022 Share Posted August 30, 2022 I did the same and went to a Wilson titanium, using the FTM spring. It’s worked great so far. Link to comment

Scrounger Posted August 31, 2022 Share Posted August 31, 2022 Agreed. I always carry spare pins. If you watch Max Leograndis, he has a spare bolt on his belt to switch out if needed running a match! Not sure if that’s still the case now that he’s running the JP5… Link to comment
