I'm sorry if this has been asked before, but I looked and couldn't come up with anything. I've been happily shooting my Varminter for two years now, and am looking for a 9mm.
Does the current RRA 9mm Carbine have a bolt hold open after the last round is fired, if using colt (or similar) magazines?
In the standard CAR A2 configuration, does the 16" of the barrel include the flash hider? Or if you remove the flash hider will it be less than 16"?
And finally, what is the thread pattern for the flash hider?
