Not a diversion there M-4 as I put the tangent out there. I guess one might find a German bolt gun in 0.276" Westley Richards, 0.276" Rigby/7x57 Mauser, before a discovery of one in 0.318" Westley Richards. Anyway, I was looking for a menacing or crosshatched muzzle but here Immanuel Meffert held to less adornment. The tubes look nice & meaty. The tube length most definitely should be an integer number in cm like 68, 69, 70cm, etc. Have you posted the length already and I missed it?

Kind Regards,

Raimey
