This vertical adapter mounts in to the body of the gun where the hose or foregrip currently is in place. It lets you attach to the bottom of it any standard ASA item like regulators and expansion chambers. This piece does not have a built in pin depressor so you can screw a CO2 tank in to it but it won't depress the pin to make air come out.

This is a right hand threaded adapter.

Fits perfectly in to the recesses of the receivers for:

BE Avenger 2
VL Orion
VL Triton 2
Please be aware that some of these guns were originally made with left hand threaded receivers / bodies, so make sure that your receiver is right hand threaded (lefty loosey, righty tighty) before ordering this part.

No pin depressor on the female side.
