The Lahar-30L provides increased sound reduction where it is needed most. Built on the foundation of the Lahar-30 with the addition of 3 additional baffles to provide increased internal volume-the Lahar-30L is a great candidate for magnum rifles or other hosts that traditionally produce a higher level of sound. This model features an all-black finish and is rated for centerfire rifle cartridges from 5.56x45mm NATO to .300 Win Mag. The suppressor comes included with a 5/8x24 TPI direct thread adapter. *Sound reduction ratings are approximate based on measurements by the manufacturer and may vary depending on firearm setup and environmental factors.*
