When you’re building a new rifle, or upgrading an off-the-rack weapon, you need to choose a quality AR rail system that’s ready to go anywhere and do anything. If you’re done with feeble forends that twist, flex and threaten to collapse, it’s time to move on to greener pastures. The CMT Tactical AR-15 UHPR M-LOK Rail System is designed to provide the mounting and grip surfaces you want with the stability and strength you need.

A Quality Rail Without the Hassle

Whether you need an AR Rail System for a new build, or to upgrade an old favorite, the CMT Rail System will fit seamlessly with almost any weapon you choose. The high strength of CMT’s extruded aluminum rail is paired with CMT's patent-pending stainless steel rail mounting attachment. The rail is timed to your upper with anti-rotate tabs so there’s no guesswork involved. You won’t need to shim the barrel nut or go through a lot of trial and error trying to keep the rail clear of the gas block and tube. The CMT Rail System is designed with those clearances in mind, so you won’t have to worry about contact with the gas tube and you don’t have to worry about compatibility with most gas low profile blocks. CMT thinks of everything, right down to the barrel nut wrench. They’ve included one right in the package.

Choose the Length You Need and the MOD You Want

Whether you need a full-length 15-inch M-LOK Handguard or a shorter version for your new build, the CMT AR Rail System comes with the features you want. If you prefer a full Picatinny top rail, choose the UPHR Rail System MOD 2. If you don’t want the full Picatinny treatment, choose the MOD 1, which utilizes Picatinny Rail only at the ends of the 12 o’clock rail surface, leaving the majority of the top surface match to the M-LOK style. Either MOD is available as a 6.7-inch, 9.5-inch, 13.7-inch or a 15-inch M-LOK Handguard. Choose the option that suits your mounting needs and let Wing Tactical give you the edge you need with a CMT AR Rail.
