(R)ecoil (R)eduction (D)evice (4)ports (C)ompensator (28) 1/2x28 threads (Slim) Slim deisgn (9)mm
Our popular RRD-4C-S (slim) muzzle device now in a pistol caliber kalash friendly form. This RRD-4C-S was designed specifically with the NAK-9 pistol in mind. Unlike our other 1/2-28 threaded RRD-4C devices, this device will install on your NAK-9 (or similar) and index using the muzzle device detent pin in your front sight block.
Product Specs:
*When testing these devices with rifle calibers, we found that high rates of fire such as full auto or “mag dumps” could cause damage to the device due to the excess heat, pressure, and gasses from unburnt powder on shorter barrels.
*This device is designed specifically for the NAK-9 pistol/SBR. This product may fit other firearms with the same thread pitch however the detent notch may not align.
Easy install if you have a detent pin, like I have on my nak 9. No grease or anything needed; just hold the detent pin down with your fingernail while screwing on the brake. For performance: 5 stars. I'd say the recoil reduced to the level of a 22lr(or maybe a tad more) while firing the pistol like a pistol(no stock). And best of all it only increases the noise by about 10-20%. Highly recommend, does as advertised, easy to install, high quality.
