FS new 15" free float Midwest Industries SS-15" Gen2 w/ extras $155 shipped I have these on 3 of my rifles and have installed on many builds for friends. This last one is collecting dust. 15" length, black These are beautifully-machined: every little cut and hole is chamfered. The 1.5" diameter feels great and the 15" length makes it ride the bags well (I shoot off my pack when I hunt so this helps). Perhaps my favorite thing about this is that they don't screw you on the accessories later. Included is the nut, wrench for 1/2" torque wrench/ratchet, several rail sections, a QD swivel socket, loctite, and wrenches. I'll sell to a Grendeler for $155 shipped to lower 48 (quote elsewhere). These are $189 at Midway (although I'm sure cheaper elsewhere, not this cheap). I can take credit card, paypal, MO, etc. and will ship immediately after payment.
