Muscle Brakes

Muscle Brakes

We are now the direct distributor of the Center Shot Rifles "Muscle" Brakes and CSR muzzle brakes.  For those of you not familiar with the muscle brake it was designed to be extremely shooter friendly.  With the first port being 90 degrees it shears the back blast off from the angled ports, to prevent the "blast/concussion" effect from distracting the shooter. These brake are made of 416SS, and hardened to 30 Rockwell.  Benefits to the Muscle brake are increased recoil reduction, no back blast to the shooter as compared to typical angle port and radial port brakes, and the brake to barrel joint can be tapered and blended for a seamless appearance.  (Turning down the OD of the brakes is not recommended and may affect performance.)  We offer many different models of muscle brakes to best fit your individual wants and needs.

Mini Muscle BrakeWas designed for cartridges of 30 caliber and less burning 65 grains of powder or less. The best performance is in the .22cal. thru 7mm standard cartridge, and any of the varmint class cartridges. The slabbed version is great for light deer/sheep rifles.

9/16x24 tpi, slabbed model fits a muzzle diameter of .620" to .850", round version up to .990".


Mini Magnum Muscle Brake: Now fit a Muscle brake to your factory magnum rifle! Was designed to fit factory sporter weight barrel contours with muzzle dia. of .620" to .850". This brake is very close in size to the mini, just a tad longer for the increased port volume.  This brake was designed to work with magnum cartridges, yet maintain a smaller profile. Where the original mini excelled with the smaller chamberings, this new design should be perfect for sporter barrels in WSM and standard Magnum cartridges. It will also reduce the recoil on the Ultra Mags to an acceptable level.

New: 1/2x28, slabbed model fits a muzzle diameter of .560 to .850".   

9/16x24, slabbed model fits a muzzle diameter of .620" to .850".

Original 3 Port Muscle Brake:  This brake works on anything from the 243 to the 338 Lapua. 45 to 95 gr of powder is covered pretty well by the one and only original muscle brake.

5/8x24 tpi. slabbed model fits muzzle diameter of .685" to .990". round version up to 1.225".  The top ported 3 port is the preferred model for specialty handguns, also works great on rifles. 


5 port Muscle Brake:  This brake came out of the need to give the same performance as the magnum 4 port but in a much smaller package.  This will tame any magnum to where a little kid can shoot it. 

5/8x24 tpi. slabbed model fits muzzle diameter of .685" to .985".  the round version is 3/4x24 tpi and fits muzzle diameter of .830" to 1.230"


Magnum 4 & 5 Port Muscle Brake: This mighty brake was designed for the Chey tac and Snipe tac sized offerings. Anything burning over 100 grains of powder will feel like a pussy cat with this brake. (short of the big 50).

Having absolutely no pain at anytime during or after will let me practice a lot!!! Thanks for a great product, and even better customer service!!!"
