Firing pin cleaning for M4-22 and aluminum alloy type



Log in to see fewer ads
I'm a new M4-22 Elite owner. Does anyone know the type of aluminum alloy that is used in the M4-22? Is it 7075 or another alloy? Also, does the firing pin require cleaning? If so, how is the firing pin removed? Thanks.

I would say generally unless the firing pin is real gunked..I think just spraying through it with some brake clean would suffice without disassembly..Not familiar what Tippman did as far as a Bolt design..But I would think if anything like a CMMG BCG setup..There should be a simple pin to remove to get the Firing pin out..

You can probably find a disassembly manual on their website maybe?

I have only seen pictures of the bolt, but it looks as if a roll pin is driven through the bolt and FP vertically.

The manual only states to clean the bolt including the end which contains the extractor and tip of the firing pin. There is no mention of removing the firing pin in the manual. The manual also warns not to disassemble the M4 components further than what's stated in the manual. So, I guess the firing pin is not to be removed.

Probably just another over complicated Bolt design..

Just use Brake Clean or similiar..Should be fine..

It is a cast aluminum not forged, so it could be anything. As far as the firing pin, I have a 2 year old Elite with over 60k on it. Never did anything special to the firing pin other then an occasional spray of brake cleaner when it started to get sluggish.
