Frequently Asked Questions

How does the Lantac M-SPEC 22S suppressor handle sound suppression on a .22LR pistol?

The Lantac M-SPEC 22S offers adjustable sound suppression via its modular baffles. Testing indicated that configurations with 3 to 5 baffles provided excellent sound reduction, often making .22LR rounds audibly quieter than mechanical firearm noise, with 3 baffles being a recommended balance.

When mounted on a .17 HMR rifle, the Lantac M-SPEC 22S suppressor resulted in an approximate 1-inch downward shift in the Point of Impact compared to firing the rifle unsuppressed. Re-zeroing optics is advised.

Can the Lantac M-SPEC 22S be used with calibers other than .22LR?

While officially rated for .22LR, the Lantac M-SPEC 22S was unofficially tested and showed performance with calibers like 5.7mm and .17 HMR. However, users should exercise caution and understand that these are not official ratings and may affect suppressor longevity or safety.
