Want to put a brake on Tikka t3x, recoil not a major issue, more to protect the crown. Looked at a VG6 Gamma 308 brake at a local shop and would not thread on. Are the Tikka's metric?
It depends on model but if itsn't 5/8-24 (like VG6 Gamma 308), it should be 18x1 mm, which is common for european rifles (Tikka/Sako, Bergara Eu, Cz)..
