Well about a year since the Muscle brake debued, and I have some new products along the same lines.
The original 3 port Muscle brake will be available in 3 configurations.
Slabbed with top porting (on all baffles comming in from the sides)
The Mini Muscle Brake is a scalled down version that will come;
This mini brake works great on smaller dia. barrels, looks better as it is not quite as big, and has proven very effective on cartriges at or below the 300 WSM
level. although originally designed as a varmit brake it is working awsome on larger cartriges. The slabbed version of this brake is new to cut down on the size and weight for lite rifles.
The original 4 port Muscle brake will now be slabbed off at 1.25" tall but remain 1.5" wide,
This brake works great on the chey tac and snipe tac cartriges. I put one on a 17 lb. 338 lapua and it kicks like a sporter weight 223
New will be a 4 port that is scaled the same as the original 3 port, except slightly longer to acomidate the extra port. This brake will be slabbed and will be the goto brake for the 300-338 ultra mags and 338 lapuas.
I will be picking up a large batch at the cnc shop this week. Then off to the Varmit hunters Jamboree.
