Airsoft Mutation BSS CNC Delrin Cylinder Head for V2/V3 AEG

Retaining Compound (Loctite 638) is still required to keep the stem in place.

Bronze Switchable Shaft Cylinder Head

Unlike other aluminum cylinder heads, the preinstalled pad is extremely durable. Machining quality on these cylinder heads surpass all other brands tested and the nozzle section is incredibly smooth which reduces nozzle O-ring wear and leads to the nozzle returning to battery very quickly for consistent fps in high rps builds. 

• 5.41mm ±0.01mm OD stem
  For superior nozzle fitment - Begone wobbly nozzles and air leaks
  
  
• Bronze (Proprietary heat treated alloy) stem
  Offers exceedingly low friction while having significantly more abrasion resistance than aluminum. It will not gall unlike aluminum and steel stems.
  
  
• CNC Delrin main body
  For increased gearbox durability and reduced noise. Design ensures it will not crack under high loads unlike other Polymer Cylinder heads.
  
  
• Integrated NBR pad
  For high abrasion resistance, low compression set and low deadzone. 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.
