DETAILS
- description
Cut for the short AK nozzle and listed with an o-ring face, this head is machined from 7075-T6 aluminium alloy like the rest of the family.
A dual o-ring arrangement handles the air seal while a rubber cushion takes the impact of the piston head. The two do separate jobs, so a head can carry both rather than one instead of the other.
As with every head in this family, nozzle length is what actually decides fitment. Get that right first and the rest of the choice matters far less.

Anodised colours vary between production runs on these, so do not read anything into blue against amber.
Frequently asked questions
What does the o-ring actually seal against?
It seals the joint the nozzle meets, so the air the piston has compressed goes into the hop unit rather than escaping around the outside.
Does it fit long-nozzle AK builds?
No. This is cut for the short nozzle. Check what you removed before ordering.
What is 7075-T6?
A high-strength aluminium alloy used where a part has to stay dimensionally stable under repeated load. It is the standard construction for this family of heads.
