The Ti-Rant series features a modular design allowing for the three frontal baffles to be removed to reduce the profile of the suppressor. With the 45M series, users can quickly and easily configure the suppressor from a full-length 8-inch configuration to a compact 5.8-inch model. The entire baffle stack can also be easily removed for cleaning or maintenance. This model is optimized for use on .30 caliber pistol cartridges including .357 Magnum and .38 Special but can easily accommodate .22 LR rimfire cartridges. The 9M-HD series is rated for subsonic .300 AAC Blackout only. This product does not include a piston and must be purchased separately. *Sound reduction ratings are approximate based on measurements by the manufacturer and may vary depending on firearm setup and environmental factors.*
