First Firearms II

[bonjing]

Haven't brought it out in a while, but I'm running a dedicated cmmg upper and redi-mag S&W magazine adapter. I don't recall having any complaints about it.

I did have the cmmg adapter and mags. It had problems with bolt hold open and mags were a pain to load.

S&W mags are so much easier to load, best switch I made. Sometimes the last round bolt hold open wouldn't work but the ease of loading the magazines more than makes up for it.
