Elf Owl Chassis


  • Do you intend do build a rifle or pistol on your chassis? Please note that any firearm with a barrel less than 16" must be built as a pistol unless it is registered as a short barreled rifle.

    Choose either our "Elf Owl Telescoping Stock", or one of our stock adapters. Stock adapters allow you to install various aftermarket stocks on your chassis. The "AR-15 Buffer Tube Adapter allows you to install any stock that uses an AR-15 buffer tube, while the "1913 Picatinny Adapter allows you to mount stocks that use 1913 Pic rail to attach to your rifle.

    Pistol brace adapters provide different options for mounting pistol braces to your chassis. You can buy the brace yourself, or for certain braces you can buy it from us! A pistol brace adapter and brace are not required for the chassis to function, but they will make it easier to shoot. The "AR-15 Buffer Tube Adapter allows you to install any pistol brace that uses a mil-spec AR-15 buffer tube, while the "1913 Picatinny Adapter allows you to mount braces that use 1913 Pic rail to attach to your pistol. Our "Telescoping Tailhook MOD 1 Adapter" is designed to work with the Tailhook MOD 1 pistol brace and is not compatible with any other brace type. Also, if you want to buy just the chassis for now, and then decide what brace you want later, just choose the "Base Configuration", the adapters will also be available to buy standalone.
