Works well with leather or synthetic seal guns of all ages.
Supplied with machined front and rear guides, tar, and a custom spring.
Power level depends on the gun, seal type etc. But this kit puts it at factory spec. or where it should be given its capabilities.
The spring itself has 17 ft. lb possibilities but the HW35 with its short stroke and 30 mm tube can not make power like this. Kit is vibration free. Works in both calibers.
