I just rcd one:
S&W M&P15-22 Charging Handle (Ambidextrous) This is really slick, I'm impressed.
My 15-22s are for NSSF Rimfire Challenge, Steel Challenge, Bowling Pins etc. They're bare bones competition oriented with no "just looks cool" stuff. The Tacticool22 charging handle is a nice addition. I was a little leery about it "only" being aluminum as on my "real" AR's I use steel charging handles but it really works. Positive feel, pulls from either side and doesn't flex and bind like the OE piece does. Money well spent.
Two thumbs up.
