Stag AR10 MLOK 13.5" Handguard
This is a fantastic product, very light-weight and well engineered, just like the Stag AR10 Upper receiver it mates with. I would definitely purchase again. Two cautions, however. First. the barrel nut is thicker than a typical barrel nut and has grooves for the gas tube. That means that you need to shim the barrel nut so that the gas tube aligns with a slot while within the barrel nut torque desired. Second, it comes with 5 ring-shaped shims; 0.010", 0.005", and (3) 0.001". I needed a shim of 0.009", so I had to sand down the 0.010" shim to get there.
