Just what the title says...put a new ambi BCM charging handle in my new upper, it was a tight, tight fit. Catch doesn't disengage smoothly and sounds like it drags horribly. Swapped the new CH out for a used on from another AR. This was one of those medium latch Gunfighter non-ambi ones. Same thing. BCG moves freely, so I'm hoping the receiver isn't somehow out of spec. Any ideas before I go shopping for another CH? _______________________________ The artist formerly known as AllenInWV | ||

Truth Wins |
One of the first things I did with the many ARs I've owned is replaced the standard charging handle with a BCM. In fact, I only used BCM. In many cases they were a bit tight and gritty. I put a light coat of TW25B grease in the charging handle channel and that smoothed it out. None of the BCM handles were ever problematic. All functioned perfectly. If it bothers you, you may want to put some light oil on it and work it back an forth in the upper until it smooths out a little. _____________ "I enter a swamp as a sacred place—a sanctum sanctorum.

This. I've had a couple uppers whose charging handles dragged. Slap some oil on it. Work the charging handle a few dozen times. Roll on. | |||

This is the first one I've had that does it. Feels almost like I have to push forward on the handle to get the catch to disengage. I'll give the grease a shot though, thanks! _______________________________ The artist formerly known as AllenInWV | |||

This right here. I've always used Slide Glide, but regardless, lubricate the CH. Work it back and forth. Wipe it, lube it again. Repeat as needed. "Also I heard the voice of the Lord saying who shall I send, and who will go for us? Then said I, here am I, send me." | |||

Radian Raptors and Raptor LT's fit all 4 Aero uppers I have (two M4E1 thereaded, one mil spec, one mil spec without forward assist), as do Geissele Super Charings Handles. Haven't tried BCM. Interestingly, some Geissele SSA triggers I planned to use in two Aero M4E1 lowers had drag on the hammers - you could feel them binding up somehow and if thumbed down they would not travel all the way. Newer SSA-E and SSP worked fine, so I converted over to SSA-E's. | |||
