Buy it! this is the one! - Midwest Industries 14in Combat Rail T-Series One Piece Free Float Handguard

If your in the market for Quad .......this one from Midwest and Optics planet is the standard in my opinion. Fits like a glove on my Anderson top receiver, The barrel nut torques nice and positive, others feel like their about to strip, or feels "squishy" when torque is applied...the Midwest industries Combat Quad does not. No messing around with shims and other nonsense, alignment is dead nuts on. Looked all overthe place,(internet) for the best price, Optics Planet beat them all in price, and turnaround time. Very happy with this purchase.
