Product Description The VG6 Precision LAMBDA PRS30 is the next evolution in precision rifle shooting muzzle brakes. Engineered from the ground up for the discerning precision shooter, this feature-packed two-piece device consists of the LAMBDA Muzzle Brake and an included Jam Nut, combining for an amazingly simple, tool-less installation. The LAMBDA PRS30 features an 11-degree target crown for enhanced accuracy and a bold four-chamber design that works in conjunction with the jam nut to self-tighten during every shot. The chamber design virtually eliminates recoil, allowing the shooter to stay on the scope and identify impacts downrange. The first chamber permits an uninhibited flow of gas to the left and right, while the three remaining chambers direct gas rearward to act as a buffer, reducing side concussion for a more comfortable shooting experience. Designed using state-of-the-art Computational Fluid Dynamics (CFD) and Computer Aided Engineering (CAE) techniques, and 100% CNC machined from 17-4PH heat-treated stainless steel with a BLACKNITRIDE satin finish, the LAMBDA PRS30 is compatible with .30 caliber up to .300 Winchester Magnum barrels threaded 5/8"-24 RH, making it an ideal upgrade for the M5 platform and any .30-caliber precision rifle. Product Highlights Advanced Four-Chamber Design: Virtually eliminates felt recoil, keeping shooters on-scope and on-target for faster follow-up shots during precision long-range shooting. Tool-Less Two-Piece Installation: The LAMBDA Muzzle Brake and Jam Nut combine for effortless setup; the jam nut self-tightens with every shot to maintain secure positioning. Premium 17-4PH Heat-Treated Stainless Steel: 100% CNC machined construction delivers a surface hardness of 68RC with the durability and corrosion resistance required for demanding field use. BLACKNITRIDE Satin Finish: Provides a sleek, half-gloss appearance with enhanced surface protection against wear and the elements. Broad .30-Caliber Compatibility: Threaded 5/8"-24 RH to fit any .30 Cal up to .300 Win Mag barrel, including the M5 multi-caliber platform, offering exceptional versatility.
