Key Feature

• The SHORT RECOIL SYSTEM is an optional extension for the SARB-15 kit, designed exclusively for Airsoft GBB platforms.
• It allows you to retain the original BCG and convert various AR/M4 GBB systems into a bullpup configuration.
• With the extension installed, the length of pull reaches 16.3", aligning with standard bullpup proportions. Thanks to smart ergonomic design, handling remains natural and comfortable. 

KIT Includes:

• Rear stock extension adapter (SLS 3D Fusion printed)
• Short tube extension
• CNC short buffer
• Short recoil spring

Note:

The gold short buffer tube, end cap, and rubber butt pad are reused from the original SARB-15 kit.
This kit does not include a BCG; please use your original BCG.
