The TT Terminator muzzle brake is KG Gunkoted Black & opened out as standard to take a maximum calibre of the .308
It is specifically manufactured to fit onto the Tikka CTR & Ruger Precision rifle.
Easy DIY fit, no gunsmithing required, using a locking nut to index it to the barrel.
TE with nut is 25mm, 0.98” diameter, 72 mm, 2.83” long, 95 grams, 3.35 oz, 5/8×24 thread.
Ports are 90 degrees to the ground to reduce disturbance. The ports are angled back away from the shooter to minimise shooter discomfort and maximise performance.
The standard through hole is for .308 & requires opening up to 0.025-0.030″ over calibre size if fitted to larger calibres.
The TT performance is the same as the T3 Terminator Muzzle Brake.
