C3 Billet Lower - Stuck Buffer retaining pin

[Aegis]

I picked up a C3 Enhanced Billet Lower in a trade, but it didnt have a stock on it. Finally got around to putting one on, to find out the retaining pin for the buffer doesnt fit right. I feel pretty shafted right now....

Its stuck in there. I cant get it out with pliers, Im more than a little mad, so ive stepped away before I break something.

Im open to suggestions.

Let it soak a bit in liquid wrench, use a q-tip with acetone or brake cleaner to wipe the tip clean and try again. A few gentle taps may loosen its bite just enough.

If nothing else works, drill it, tap it, put a screw in it and pull it out. (If the spinning drill bit doesn't grab and pull it out) Be careful not to let the bit hit the wall or bottom of the hole

yeah, this is what its looking like.

and then carefully sand out the hole a little bit to accept a new one.

When you get out out, try a different pin. You don't want to modify the lower only to find out it was an out of spec pin

I had the same problem with my C3 enhanced lower. i took sandpaper and went to town on the retaining pin. Works great now. Dont feel bad, C3 is known for having extremly TIGHT tolerances. I had to take a file to my magwell to get my Pmags to drop free.

I would sell it to me really really cheap.......that'll make you feel better.

It's not tight tolerances.........it's called out of spec

Yep, x3. The C3 lowers are great, but quite often they don't fit properly with a lot of different uppers. The suggestions above all are good ideas, I'd do the drill bit as a very last resort.

Same here. Remove the pin as suggested, then try a new and sand it until it fits.
