Frequently Asked Questions

What is the SureFire suppressor mount system known for?

The SureFire system is recognized for its quick detach mechanism and taper lock technology. This design ensures excellent alignment, minimal point of impact shift, and reliable return to zero, making it a preferred choice for military and law enforcement.

How does the Dead Air KeyMo system attach a suppressor?

The Dead Air KeyMo system uses a spring and ratcheting mechanism combined with a taper lock. It allows for quick attachment and detachment without pressing buttons, but users should only hand-tighten it to avoid getting the suppressor stuck.

What is the advantage of Dead Air's Xeno mount?

The Dead Air Xeno mount features a left-hand thread (on non-rimfire models). This unique design allows users to apply significant force to unscrew a stuck suppressor without accidentally unscrewing the muzzle device, as turning the suppressor righty-loosey tightens the muzzle device.

What is the main difference between Dead Air's Plan B and Xeno mounts?

The primary difference is length and thread direction. The Plan B is designed to be shorter for a more compact setup. The Xeno, conversely, uses a left-hand thread (except for rimfire) which offers an advantage when removing stuck suppressors, though it is slightly longer.
