Features & Specs:
Model: ARP9 / ARP556 Battery Extension
Compatibility: ARP9, ARP556, Raider 2.0E Long
Very easy to install so you can add longer and bigger batteries in your rear stock/buffer area.
Once installed, a 9.6v 1600mah nunchuck or 11.1v 1200mah stick lipo will fit the ARP9 / ARP556
Must have for those that want flexibility with battery space.
Drop-in, no tools needed.
This is a must-have for any ARP9 user!
Its a well thought-out, and well-made, piece. Simply clicks in place, between the current stock, and the OE endcap. You just add it in, in a few seconds. You lose a little collapsible space, but it still gets plenty short.
