Weather you have the tube version or the bottle version of the Avenge X, retrofit your gun into the Saber Tactical Chassis. The chassis is very easy to install. It gives you a long bottom ARCS Swiss rail as well as picatinny in the front and plenty of MLok slots to attach accessories. 

Features:

• 6061 Aluminum
• Black anodize
• Includes a buffer tube adapter if you want to use the factory rear tube and stock, or you can use any AR compatible buffer tube and stock combination.
• Compatible with tube and bottle version

Note: If you do not have the Avenge X tactical model, you will need to buy an AR compatible grip as well as AR buffer tube and stock of your choice.
