  • WATERS RIFLEMAN - HIGH POWER MUZZLE BRAKES
    DESIGNED BY SCIENCE, PERFECTED BY EXPERIENCE, PROVEN BY RESULTS. NO MORE PAYING RIDICULOUS DOLLARS FOR A PIECE OF THREADED STEEL WITH HOLES.
    WHY ARE THE WR RANGE OF BRAKES SO GOOD? Thanks to 26 years in fluid mechanics, using numerical analysis, CFD and 3D modelling, we have unlocked the secrets of a muzzle brake and the flow of hot expanding gas through it. 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.
    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.
    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...
    WR GAS MONGREL HYBRID is the best in class for recoil reduction while offering the brake performance and ergonomic benefits for both competitive shooters, varminters and hunters. WR GAS MONGREL HYRBID A$174ea. AVAILABLE NOW. WR GAS MONGREL HYRBID MAGNUM A$187ea. AVAILABLE NOW.
    If this brake were made by anybody else, it would sell at least at double the price...
    The Gas Mongrel Hybrid muzzle brake was created to be the best of both the WR Ultra Comp and the WR Gas Mongrel muzzle brakes (each the world best in their class).Using the best of WR design specs from the GM and UC brakes, the GM hybrid more so polarises gas direction and dispersion to increase gas velocity to the sides of the bullet axis, reducing felt blast while continuing to minimise muzzle movement during bullet exit.If your needs are for maximum brake, minimal muzzle movement and bounce, minimal ground disturbance, reduced felt blast and slimline brake for practical applications, the Gas Mongrel Hybrid is the best pound for pound brake in the world. It doesn’t get better than this.Reduce muzzle walk with increasing shot-to-shot heat build-up. The GM hybrid is made ULTRA lightweight, thanks to being made from 7075 Aluminium, and a massive increase in surface area will considerably help absorb and dissipate heat away from the muzzle area.
    Like all WR brakes, we continue to campaign the non-integrated clock nut. Why? Our math and simulations show modulus of elasticity is causing many disturbances we wish to avoid. WR are advocates for a straight brake thread to a jam nut off the brake shoulder as the BEST fitment method. - BORE sizes: - Up to 6mm (0.243), - Up to 7mm (0.284), - Up to 30 cal (0.308). - Up to 33 cal (0.338). - Up to 37 cal (0.375). - Up to 41 cal (0.416).

    - Recoil reduction: Over 80 cm² of negative surface area results in Approx 70 to 84% recoil reduction, depending on barrel gas pre-load volume, bullet body length and bullet exit energy. - Vertical jump: Approx 87 to 94% reduced, depending barrel twist (centrifugal momentum). - Vertical bounce: No additional bounce imposed post blast. Less than nett 2% gas directed vertically vector upward above the port top plane. - Helmholtz resonance: Minimised in-barrel time additional resonance during expelling pre-load gases by 3 step chamber design (minimising additional live fire barrel exit movement). - Shooter comfort: The GMH is a brake suitable to nearly every application, with equal capabiltiy offering maximum recoil reduction and as little proportional blast as possible. If the shooter is outdoors (recommended), the felt blast has little pressure on the firers eyes and sinuses. - Use: For competition and championships where excess recoil will directly affect maximising a potential result and muzzle blast importance not as critical. Maximises the ability to keep sights at the target looking for bullet flight vortex and bullet impact. Typically used for bullet impact sighting type matches such as Practical, ELR, Steel Challenge, PRS, Head Hunter, etc.
    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.

    WR GAS MONGREL HYBRID JUNIOR - 22 LR RIMFIRE - PURPOSE BUILD FOR PUROSE 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. Nominate the required bushing from the list below.
    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...
    Note the 22 Gas Mongrel has a top port that is blocked with a grub screw. Some 22LR ammo is so slow there is minimal pre-load, so opening this port helps with muzzle jump.

    - JAM NUT - for muzzle brake clocking. - Hex nut, 2 threads deep (apprx 5mm (0.195") thick). - Using a jam nut to clock a brake is the BEST method. NOTE: WR do NOT recommend using the integrated nut method on many brakes is nice and convenient, but due to rigidity and an massive increase in modulus of elasticity.
