Brought it for my Pink M4 handguard, but it seems to have fitting issues as it fits but doesn't lock in place. I was reccomend this handguard by a tech, but obviously, he doesn't know what he is doing, so I brought it following his advice. I'm looking to sell for $60 or the best offer. The price is flexible, but I'm looking for enough to cover the shipping cost. Retail value is roughly $70 on evike. It does have very mild/minimal wear from fitting onto my Pink M4, but I think I'll swap out the entire outer barrel and handguard instead of trying to modify this handguard. I used it for maybe a game or two. Supposedly, it was to come with screws but I never got any except for a weird miscellaneous screw with no nut.
