MANCRAFT SDiK HPA Conversion Kit for TM M40A5 Spring-Action Sniper Rifles (4 mm)

SDiK (Sniper Drop-in Kit) for TM M40A5

SDiK by MANCRAFT is a proven system for converting manual sniper rifles to HPA power, offering extremely easy cocking with a single finger, high power output, and above all, exceptional shot-to-shot consistency, resulting in superior accuracy. The installation is simple and requires no special tools—just replace the original cylinder assembly. As a fully mechanical system, it operates without electronics or batteries, meaning no concerns about extreme weather. Power is adjusted via an external pressure regulator (required, sold separately). The hose diameter is 4 mm, making it narrower than standard 6 mm hoses used in AEG HPA kits like PDiK or Polarstar. For full functionality, you must also purchase a HPA regulator for bottle, 4mm coupling for the connection, a HPA air tank, and a HPA hose. We also recommend a pouch for the HPA bottle.
