CNC Machined POM AOE Adjustable Piston Head

Code: AEG-001

CNC Machined POM AOE Adjustable Piston Head – A  high quality, lightweight piston head for standard AEG gearboxes featuring the proven LPE AOE (angle of engagement) adjustment design, this allows for 0 – 5mm of adjustment to be precisely and easily made using LPE AOE shims while keeping the piston head centred on the piston.

The piston head body is machined from POM (Acetal) with excess material removed to minimise weight and  a full radius o-ring groove to spread the impact force and maximise durability, a seperate slimmed down aluminium core and non-bearing type bushing help to maximise durability while keeping the overall weight down. For springs over M120 an aluminium piston head is recommended.

All machined parts are fully CNC machined from solid bar in the United Kingdom by Lees Precision Engineering.
