Description

We created the NLA Sig Barrel Adapter to complement our Sig 9mm Flash Hiders and Comps.  Ensure a tight fit of your muzzle device with the adapter.

Sig Sauer added a tapered end to their MPX and MCX barrels.  This prevents a crush washer from seating correctly when installing a standard muzzle device.  The taper can also prevent proper installation of a suppressor, which could create damage to your suppressor or a baffle strike.

Our NLA Sig Barrel Adapter fits on the end of the barrel (inner tapered end faces the barrel) providing a flat surface for your muzzle device or suppressor to rest against. 

A crush washer may be used on a muzzle device, but we recommend tightening firmly and using a thread lock product to hold the muzzle device in place.

*NOTE:  We include the adapter with our 9mm muzzle devices threaded for Sig barrels.
