# MAMMOTH ARMS MUZZLE BRAKE FOR 6.5CM & 243 5/8x24"

A threaded muzzle brake built for 6.5-caliber rifles that cuts felt recoil by about 25–35% through multiple radial ports. Machined from 461 stainless steel with a .750″ outside diameter and 5/8×24 threads, it screws directly onto the barrel without indexing and comes Cerakote-finished in graphite black for corrosion resistance and a low profile on hunting or precision rifles.

Made of 461 stainless steel, 5/8x24 threads, .750 outside diameter, this custom muzzle brakes reduce recoil by an average of 25-35%. The brake screws directly onto the threads of your rifle. They are radially ported, so there is no need to index this brake. This is quite simply the easiest way to reduce felt recoil. We were able to bring the production of this muzzle brake in-house, which keeps our cost low ($74.99 retail), normally custom muzzles brakes range from $150-$200. To top it all off, we have coated this brake in a graphite black Cerakote to match most matte black rifles in current production. This brake is made specifically for 6.5 caliber rifles.

I bought this for my son's Thompson Center Compass II 6.5 creed moor bolt action build. Great gun and now even a little less recoil with this Mammoth Arms Muzzle Brake. No issues at all. I was thrilled to find this at KYGUNCO. Worthy addition!

I gave 4 stars only because it threaded on with out any issues and looks good. I have not had the time to take the rifle out and test the muzzle brake

I was amazed how little recoil I felt from the 6.5 creedmoor rifle I bought this for. It seemed to me that it didn't even kick as much as my AR 15 rifle in .223. So glad I made the purchase for my new rifle.

I bought this for the looks, but after hearing how it makes my rifle bark, it is an added feature. It looks mean, and sounds even meaner!
