Built like a tank but not very brakey - Glfa Muzzle Brake .458 Socom 5/8"-24 Threads Black

I have this affixed to my tromix 16" 458 socom barrel. It goes on fine except that there are no surfaces to get a wrench on it. I ended up shoving some punches through the holes in order to get it to mount properly. After shooting some rounds with and without the brake it doesn't seem to make a huge amount of difference in felt recoil. A good thread protector but not much else. but for 43 bucks what do you really expect.
