T3 Terminator muzzle brakes are designed for .223 to 338 Lapua Magnums on barrels up to 25mm diameter.  Standard hole size 6mm, must be opened up to correct calibre by a Gunsmith.

• 25mm Diameter, 69mm long, Weighs 90-115 grams
• 308WIN, 7mm REM Mag, 338LM

All brakes have flats for a spanner and so they can be easily fitted by the gunsmith. Ports are 90 degrees to the ground to ground 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 and installed by a Gunsmith.
