  • WATERS RIFLEMAN - RIMFIRE MUZZLE BRAKES
    DESIGNED BY SCIENCE, PERFECTED BY EXPERIENCE, PROVEN BY RESULTS. NO MORE PAYING RIDICULOUS DOLLARS FOR A PIECE OF THREADED STEEL WITH HOLES.
    Helmholtz resonance is used to determine that harmonics will be induced by every brake depending based on vent orientation and gas volume and velocity - ramp up, peak and ramp down. Ramp up is the most critical as this is when the bullet is still in the barrel. The WR brakes are designed by caliber, and by ranging in the most common velocity of these calibers, to minimise any additional harmonic influences. No brake in the world takes into account these relevant considerations, AND IF THEY SAY THEY DO, THEN PROVE IT.
    WR GAS MONGREL HYBRID JUNIOR - 22 LR RIMFIRE - PURPOSE BUILD FOR PUROSEFUL PERFORMANCE.The Gas Mongrel Hybrid has been shrunk to put the best science into a purpose made light weight 22LR rimfire muzzle brake solution. As we know, the 22LR doesn't "boot" but they do move and a brake can help with that...especially if running a 22LR in a semi auto or auto. Why not use a brake to the best brake to get the most rifle control during live fire? That is what the WR GMJ 22LR brake is for. The WR GMHJ is made of 7075 alum, and hard black anodised. - weight 40grams with nut and bush. Threaded nativaly in 5/8x24.PN: 3135 WR GAS MONGREL HYRBID JUNIOR 22LR A$122ea (incl 1x brake, 1x nut and 1x bush). AVAILABLE NOW. Fitting this awesome brake to a 22RF rifle with 1/2x20 or 1/2x28 or 5/8x24. Nominate the required bushing from the list below.
    Note, above shows 22 Gas Mongrel top port blocked by a grub screw. Some 22LR ammo is so slow there is minimal pre-load, so opening this port helps reduce muzzle jump.
    Seperate bushing details: PN: 3136 Bushing for GMJ 3135 - 5/8x24M (for brake) to 1/2x20F (for rifle muzzle). Alum hard black anodise. A$23ea. Available Now.PN: 3137 Bushing for GMJ 3135 - 5/8x24M (for brake) to 1/2x28F (for rifle muzzle). Alum hard black anodise. A$23ea. Available Now. ...more bushing sizes coming...
    The WR Rimfire Gas Mongrel Muzzle Brake fits onto 3 sized threads. 5/8x24 is native of the brake, and other threads using bushes of 1/2x20 or 1/2x28.
    ALL WR BRAKES OFFER maximum brake, best case muzzle blast reduction, and are ultra light weight (less whipping on the muzzle).The hard black anodised 7075 grade aluminium material considerably helps to dissipate barrel heat away from the muzzle up to 5 times faster than steel brakes, which help minimise muzzle shape elongation at one of the thinnest and important sections of the barrel.
    THERE IS NO POUND FOR POUND MUZZLE BRAKE IN THE WORLD THAT CHECKS THE BOXES LIKE THE WR GAS MONGREL. DESIGN BY SCIENCE...
    WHY ARE THE WR RANGE OF BRAKES SO GOOD? a) Making best use of pre-load gas. b) Don't lose all the gas after bullet passes first port set. c) Consider the bullet votex thru the brake. d) Step chambers to proportion gas distribution to the subsequent ports. e) Bounce gas off gas to reduce felt blast. f) Direct gas in the most efficient laminar flow. g) Exit gas velocity and direction used to build pressure pockets to push gas to other exit ports for controlled gas volume that diminishea per port set. h) Minimise gas vacuum.
    NOTE: WR recommends always removing the brake to clean both the barrel and the brake. NOTE: Ensure solvents and obstructions etc are free from the barrel and brake before firing. WR recommends to use a reputable gunsmith to fit and clock the brake. WR does not claim a specific method of clocking as correct. No matter if the fit is brake-to-barrel, jam nut, crush washer, shim or o-ring, what ever method is employed, it should be done CAREFULY with gunsmith direction and advice.
    ===============================================================================================
    Howver most rimfire like rifles are 1/2" threads, so a bush is used, per this page, above. The brake is fitted native on a 5/8x24 muzzle thread. So only a lock nut is needed, which can be found on this page here.
