Raw aluminum pin holes

AR/M4 AR Technical Discussion

I’m curious if anyone has information regarding holes for the trigger, hammer and take down pins being unfinished and if they would egg out rapidly

From what I can gather doing a type 3 finnish at home is quite difficult so I’m sure somebody out there has tried this

Would anti-walk trigger pins help the situation in any wsy?

Thank you

One of the SOTs or whatever they’re called (I forget exactly whom) said that for a basic shop build, he just hit it with paint or some such. You could alumahide and probably be fine.

I don’t see egging out as an issue even if you did nothing after reaming the hole.

Cool I will look into that product
