AirsoftPro ZERO Upgrade Set for CYMA CM.703 and CM.707<\/h2>\n

This upgrade set provides the foundation for increasing the performance of CYMA CM.703 and CM.707 sniper rifles<\/strong>. The CNC hybrid piston with stainless steel sear, stainless steel spring guide with ball bearing and special 9mm spring form a matched assembly designed for reliable operation even when using stronger springs. The set is compatible with the original and reinforced AirsoftPro cylinder, but requires the use of the AirsoftPro AWS ZERO Gen. 4 trigger unit.<\/strong><\/p>\n

Key Features<\/h2>\n
\n

Complete Upgrade Set<\/h3>\n

The package contains a hybrid piston, stainless steel spring guide and 9mm upgrade spring<\/strong> for increasing the performance of the sniper rifle.<\/p>\n<\/div>\n

\n

Lightweight CNC Hybrid Piston<\/h3>\n

The piston body is made of CNC-machined 6061-T6 aluminum alloy<\/strong> with an anodized finish. The stainless steel sear provides high durability even when using strong springs.<\/p>\n<\/div>\n

\n

Stainless Steel Guide with Bearing<\/h3>\n

The spring guide is equipped with a ball bearing<\/strong>, allowing the spring to rotate freely during compression and reducing stress on the spring.<\/p>\n<\/div>\n

\n

Special 9mm Upgrade Spring<\/h3>\n

The spring is designed specifically for this system. Its shortened length allows it to fit into the limited cylinder space of the CM.703 and CM.707 rifles without any problems.<\/p>\n<\/div>\n

\n

Designed for ZERO Trigger\u00a0Unit<\/h3>\n

The piston uses a 90\u00b0 sear<\/strong>, making it compatible only with the AirsoftPro AWS ZERO Gen. 4 trigger unit<\/strong>. It cannot be used with the original trigger unit.<\/p>\n<\/div>\n
