SRU Precision should definitely be associated with airsoft conversion kits. Whether in the form of files for 3D printing, ready-to-assemble conversion kits or even those designed for firearms in the latest edition. The SARB-15 conversion kit allow to create a bull-pup variant from airsoft replicas and firearms based on the AR-15 lower receiver in the Mil-Spec standard. In this case, you should use models such as BRN-180, JAKL, FM-15 that have a return spring assembly in the receiver or other designs with a shortened stroke bolt assembly.
When mounting a firearms or replica into the conversion kit, we retain all of its manipulators, to which additional manipulators from the kit are applied, such as a safety above the grip, magazine release on the right side and at the bottom, similar to the G36 or AKs. For better customization, the conversion kit is adapted to the safety and grip parts in the AR-15 standard. The trigger movement transfer mechanism itself works only with classic, curved triggers, regardless of whether they are single- or two-stage ones. You can see its operation in the video below.
The kits intended for airsoft and firearms differ significantly. According to the manufacturer, the conversion for firearms uses temperature-resistant nylon, carbon fiber reinforcements and 6061 T6 aluminum with appropriate CNC processing and finishing. In the airsoft version, the housing is made of nylon with an admixture of fiberglass, and some elements are made of steel using the stamping method.
The entire conversion kit can use a firearms/replica handguard or a dedicated one from SRU Precision. Owners of Tokyo Marui MWS standard replicas can additionally purchase a short-stroke bolt assembly.
The kits are available in 3 color variants: Black, TAN and OD Green. Along with the conversion kit, we will receive a shortened stock guide with carrying sling mounts, a cheek pad that also acts as a deflector, and a receiver mount for the kit.
Depending on the selected variant, the price at the manufacturer's website for the firearm variant ranges from 429.99 USD for the basic version to 449.99 USD for the variant with a handguard. In the case of the airsoft version, the prices are 299 USD for the variant without a handguard and 349 USD for the variant that comes with one. Currently, free shipping is also offered.
