Wilson Combat’s M-LOK Rail (brand part no. TRMLOK12) is engineered to be one of the lightest, strongest, and most versatile compact free-floating rail systems available for the AR-15. Precision-machined 3, 6, and 9 o’clock M-LOK positions give you fast, easy mounting for shooting accessories in any configuration you need, and the lighter, sleeker rail profile retains the original barrel nut design so it can swap directly onto rifles already running Wilson Combat’s earlier T.R.I.M rail. Installation takes about 5 minutes with common hand tools and can be removed or replaced in the field just as quickly, and a 1.350-inch internal diameter keeps it compatible with most low-profile gas blocks. This 12.60-inch length is finished in black hardcoat anodized 6005A-T5 aluminum.
