The standard T5 threads are ¾ x 28, 7/8 x 20, M22 x 1.5, 1” x 14.
The T5 is 38mm, 1.5” diameter, 113mm, 4.45” long, 360-390 grams, 12.7-13.8 oz

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
