r/AP5

How many of you have the rounded receiver rails on your ap5/ap5p? If so is it causing any issues or is it just affecting your telescoping stocks? I’d assume since the bcg also rides in this channel that it’d eventually cause wear on those rails since less of the bcg is making contact with it. I’m just looking through previous comments and posts and seeing if I should make this a bigger deal with century. They seem to be just brushing my concerns away even though I’ve seen a few people say that they had theirs repressed back to square.

Just picked up my brand new AP5, disassembled it to clean out the factory grease and found that the bolt carrier was super rusty. Haven’t put a single round through it yet. Anyone else have a similar experience? Tips to get this cleaned up without having to send it back or replace the part? I doubt it will cause any problems with the functionality of the gun but super disappointing to pop open a new gun to find this.
