AEG Mk.II universal cylinder head V2/3 - short - without stop - EPeS

**Product name:** AEG Mk.II universal V2/3 cylinder head - short - without stop - EPeS **Technical description of the product:** **Features:** **Short nozzle:** Optimized for use with nozzles shorter than 20 mm, ideal for EVO III ASG, for example. - **Short nozzle nose:** Optimized for use with nozzles shorter than 20 mm, ideal for EVO III ASG, for example. - **Increased nozzle stroke:** Allows the use of nozzles up to 1 mm longer than standard cylinder heads, which improves the seal between the nozzle and the hop-up rubber when firing and eliminates feeding problems. - **Universal mounting system:** The cylinder head is designed for compatibility with V2 and V3 gearboxes from various manufacturers. The holes for the locking pins are optimized for Retro Arms gearboxes. - **PU rubber impact rubbers:** Available in hardnesses 70, 80, and 90 sh. Recommended use: - 70 sh for SP130 springs - 80 sh for SP160 springs - 90 sh for SP170 springs and stronger, suitable for high-rate-of-fire and high-capacity weapons (e.g., machine guns) for continuous firing of long bursts of 100+BB. - **Recommendation:** For a given impact rubber hardness, we recommend using a spring with one degree lower strength (e.g., for 70 sh, choose a spring max. SP120). - **Version without impact rubber:** Allows use with any PU stop or Sorbopad according to the selected hardness and height of the stop for AOE adjustment. - **Improvements over Mk.I version:** Added H+PTFE surface treatment, extended nozzle nose length, modified nozzle nose diameter, and redesigned impact rubber for better impact energy distribution. - **Material:** Made of EN AW 7075-T6 aircraft-grade aluminum with H+PTFE coating for ideal sliding properties and high abrasion resistance. - **Sealing components:** Impact rubber made of PU rubber and O-rings made of NBR 70 sh rubber. **Made in the Czech Republic** **Note:** This is a version without impact rubber, which can be purchased separately.
