Product Description The Wilson Combat TRMLOK15 M-LOK rail is a compact, free-floating AR-15 handguard engineered to be lightweight, strong, and highly adaptable for modern accessory mounting. Precision machining provides M-LOK attachment positions at the 3, 6, and 9 oclock locations for fast, secure installation of lights, grips, and other shooting accessories while maintaining a sleek profile. Its barrel nut design was retained from the original Wilson Combat T.R.I.M. rail system, making it a convenient upgrade path for users swapping from the older TRIM-style handguard. Installation is designed to be quick with common hand tools, and the internal diameter is intended to clear most low-profile gas blocks.
