I recently acquired a Fostech DefendAR-15 bump-fire stock for a killer price, and I just finished installing it on a 5.45x39-chambered M4gery. For some time, I've had another M4gery in the same caliber, with a first-generation Slidefire SSAR15 stock. I have yet to take both to the range to compare them back-to-back, maybe with the uppers switched after some shooting (one is carbine gas length, the other is a middie, and they have different comps.) Would anyone care for a comparison report of those two stocks, as well as a range report? Or would that write-up not even merit a golf clap?
