In collaboration with Burst-head Japan, the Butt-stock Extension design attaches to the rear of the G&G ARP9/ 556 to ensure the gun can be rested on the shoulder securely to restrict slippage. 

- Super easy to install! You simply insert the plates on each side and then tighten the screws.

- Secures the Stock-butt securely on your shoulder with maximum comfort and stability.

- Expansive surface grip to avoid slipping while taking aim.

- Made from injection-molded ultra-tough polycarbonate and will withstand all forces from in-game situations.

- Can be placed vertically for easy storage without tipping over.
