The LPM Liberty Bell muzzle brake from Liberty Precision Machine is a precision-machined .30-caliber recoil-mitigation device with a 5/8x24 thread pitch, 17-4 PH stainless construction, and a 13/16" hex rear for installation. Internal porting redirects gas laterally to noticeably reduce felt recoil on .30 rifles, and the device is compatible with the Q Plan-B suppressor mounting system for a future-proof upgrade path.

Specs & features:

• 17-4 PH stainless steel, CNC-machined and timed in a single setup for concentricity
• 5/8x24 thread pitch — fits standard .30-caliber muzzles
• .30-caliber bore (.308 / 7.62 NATO / 6.5 Creedmoor host barrels)
• 13/16" hex flats for a clean wrench install
• Q Plan-B suppressor adapter compatible
• Made in USA by Liberty Precision Machine

Verify muzzle thread pitch and bore diameter against your barrel before install. Use a crush washer or peel washers for proper timing; thread sealant is optional on stainless threads. After the first 50 rounds, re-check timing and torque to factory spec.
