K31 Clamp on Damper
This new Clamp On Muzzle Damper is designed to work with the K31 rifle.
The unit functions successfully as a Harmonics Damper and will, with the GP11 cartridge or your successful reloaded cartridges, effectively reduce overall group sizes.
That is dependent on your reloaded cartridge being proven to you as a successful reload.
There were no field tests run on "floated" barrels.
