TANO 13.0 Rail
13.0 in. free-float handguard for AR-15 uppers. Suits a 16 in. barrel on a mid-length gas system. Continuous top rail, M-LOK, no barrel-nut timing.
Limit 5 per order.
Part no. CMT-TANO-130
The TANO 13.0 Rail is a free-float TANO handguard machined from billet aluminum and finished in CMT's Tanodized hardcoat. It carries a continuous MIL-STD-1913 top rail that indexes flush with a flat-top upper, and M-LOK on every flat below the top rail.
CMT's barrel nut does not have to be timed. There is no shim stack to chase and no clocking the nut to clear the gas tube — torque the nut, slide the rail on, and clamp it. That removes the single most common source of a canted rail and lets the same nut come back off for barrel work without a fight.
Fitment
- Mil-spec AR-15 flat-top upper receiver
- Intended for a 16 in. barrel running a mid-length-length gas system
- Clears low-profile gas blocks up to .750 in. journal diameter
- Will not clear a standard A2 front sight base or a clamp-on gas block with an oversized body
In the box
- TANO 13.0 Rail
- CMT barrel nut
- Clamp hardware and wrench flats sized for a standard armorer's wrench
Installation. Fit and torque the barrel nut to the value in the instructions with the upper in a proper vise block and reaction rod. Confirm the gas tube passes through the nut without contact before clamping the rail, and verify gas-block alignment before the first live round. If you are not equipped to torque a barrel nut, have a qualified gunsmith install it.
