AEG Mk.II universal cylinder head V2/3 - extra long 70sh - EPeS

Product: AEG Mk.II universal V2/3 cylinder head - extra long 70sh - EPeS Product description: - Long nozzle nose optimized for nozzles shorter than 32 mm, such as BREN ASG. - The increased stroke of the nozzle arm allows the use of a nozzle up to 1 mm longer, which improves the seal between the nozzle and the hop-up rubber when firing and eliminates feeding problems. - The unique cylinder head mounting system ensures universal compatibility with V2 and V3 gearboxes from various manufacturers. - The holes for the locking pins are optimized for Retro Arms gearboxes. - Impact rubbers made of PU rubber with hardnesses of 70, 80, and 90 sh: - 70 sh for springs up to SP130 - 80 sh for SP160 springs - 90 sh for SP170 springs and stronger, suitable for high-rate-of-fire and high-capacity weapons. - Recommendation: For a given impact rubber hardness, use a spring with one degree lower force (e.g., for 70 sh, choose max. SP120). - A version without impact rubber is available for use with any PU stop or Sorbopad depending on the hardness and height of the stop for optimal AOE adjustment. - Compared to the Mk.I version, H+PTFE surface treatment has been added, the nozzle nose length has been extended, the nozzle nose diameter has been modified, and the impact rubber has been redesigned for better impact energy distribution. - Made of EN AW 7075-T6 aircraft-grade aluminum with H+PTFE coating for excellent sliding properties and high abrasion resistance. - Impact rubber made of PU rubber and sealing O-rings made of NBR 70 sh rubber. - Made in the Czech Republic.
