The T6 Terminator muzzle brakes are designed for .375 Cheytac improved to 50 BMG on barrels up to 50mm diameter.
All Terminator Muzzle brakes have flats for a spanner and so they can be easily fitted by the gunsmith. Ports are 90 degrees to the ground to minimise debris disturbance. The ports are angled back away from the shooter to minimise shooter discomfort and maximise performance. The through hole requires opening up to 0.025-0.030″ over calibre size.
It is recommended the rear of the brake be tapered down to the muzzle diameter.
The standard T6 threads are 7/8 x 14, 1” x 14, 50mm, 1.97” diameter, 153mm, 6” long, weight, 985-1015 grams, 34.7-35.8 oz
The T6 has 10.2mm through hole for .375 & requires opening up to 0.025-0.030″ over calibre size when fitted to larger calibres
