Change the front module on your H2 or Optima silencer and it will make your gun even more suitable for sport shooting and driven hunts.
The EndCap brake mounted on your silencer will reduce both recoil and barrel rise siginificantly, and you still have the advantages of an silencer.
The A-TEC ECB is currently available for these models:
A-TEC H2
A-TEC Mega H2
A-TEC Optima 45
