Retaining Compound (Loctite 638) is still required to keep the stem in place.
Bronze Switchable Shaft Cylinder Head. A cylinder head unlike any other.
Designed to last a lifetime, this cylinder head incorporates many features that sets it apart from the norm. Threaded bronze stem allows removal of the stem to allow replacements to be installed in case of serious damage caused by incorrectly aligned components and dirty/gritty environments. Future stems of varrying lengths will allow perfect nozzle fitment, no matter the nozzle length. The main body being made of genuine delrin ensures the least amount of shock is transferred to your gearbox, granting you the ability to use weaker gearbox shells without snapping the front off after a few tens of thousands of rounds.
- 5.41mm ±0.01mm OD Stem
- For superior nozzle fitment - Begone wobbly nozzles and air leaks
- Bronze (Heat treated alloy) Stem
- Offers exceedingly low friction while having significantly more abrasion resistance than aluminum. Where aluminum galls and fails, sending metal grit onto your bucking and down your barrel, this one will not.
- CNC Delrin main body
- Dramatically reduces gearbox fatigue and reduces piston impact noise. The extremely thick design + rubber pad distributes the forces to the outside of the cylinder head which ensures it will not crack under high loads unlike other polymer cylinder heads that crack around the stem.
- Integrated NBR pad
- For high abrasion resistance, low compression set and low deadzone. The pad acts as its own O-ring so no poorly fitting O-rings in sight. Very easy to replace in case you shred it as no glue is required for complete retention of the pad.
- Tapered pad/stem
- Reduces air turbulence for improved pressure consistency and fps
The shaft is switchable with a GBB output valve key and sold separately for different set-up length such as SR25.
