M-LOK interface and aluminum construction

The UTG mounting platform uses M-LOK slots, the standard interface found on modern rifle handguards and free-floating rails. Black anodized aluminum resists corrosion and keeps weight down compared to steel alternatives. At 6.65 inches in overall length, this mount positions your light forward of the receiver without excessive leverage. Whether you're running a duty-ready rifle or a precision platform, M-LOK modularity lets you adjust positioning. Explore more PC §32100 exempt revolvers and complementary equipment here.

Frequently asked questions

What rail systems does this M-LOK mount fit?

This mount works on any rifle handguard or rail featuring M-LOK slots. Common platforms include AR-15 handguards, modern AK variants with M-LOK rails, and aftermarket mounting systems that follow the M-LOK standard specification.

Is the 4.86" length suitable for compact rifle builds?

The 4.86" measurement fits mid-length and carbine-length handguards well. On shorter setups or pistol-caliber carbines, verify your handguard has sufficient rail real estate forward of the receiver to mount securely.
