I'd like to take credit for it... but it was PG's idea... I was assembling parts to do an 18" barreled 7/08 when this came up.
It balances about 1.5" in front of the front action screw.... which is a bit better than the regular 8400 IME.
Next to a 22" barreled Tikka...
Yep, and could be even shorter with a different can.
To go shorter, and get equal performance.. you gotta get fatter. Volume is a critical component to suppressor effectiveness. Just like rifle rounds.... there's no replacement for displacement.
You better pray to the God of Skinny Punks that this wind doesn't pick up......
