Frequently Asked Questions

What does a vented front cap do? It caps the front of an IWI-pattern mount system while venting propellant gas, rather than functioning as a muzzle brake or suppressor baffle stack itself.

Is this a regulated NFA item? No. It is an ordinary Title I mounting accessory, not a firearm silencer, so no ATF paperwork or tax stamp is required to purchase or own it.
