For those who can, and do.

When designing a rail, we started with our customer base in mind. We have been to the range doing research and development and grew tired of undoing screws and having to carry a few tools to tune the rifle the way we wanted. So we put an end to it. This isn't a tacticool gimmick, this is for you, the builder.


If you notice, our barrel nut centers on the inside of the rail extrusion. This is our anti rotation, no tabs sticking out, no extra pieces to fiddle with. Just get the barrel nut right and you're good to go.

Two-Piece Barrel Nut

We chose to use a two piece system to cinch the barrel nut down. We have an outer sleeve, that aligns the rail and locates the rail with a pin as well as a steel barrel nut with 1.25" flats for torquing the system down.

Cam Lock

Unlock the cam clamp to begin the disassembly process. This should be torqued to approximately 15 inch lbs when closed.

Take down

The takedown pin is the second step of the puzzle. Alone it is enough to keep the rail on and clamped well enough that it isn't necessary to be clamped. The clamp removes every drop of wiggle from this system.

All buttoned up

The system works together to create a sleek and secure locking mechanism for your AR-15 while allowing you the ability to clean, modify, or just show off.

Additional Information+

The first in our line of handguards the QDS 12" AR-15 handguard is a free-float handguard with the ability to be quickly detached. Weighing in at just 11 oz for the entire 12" handguard system the QDS is one of the lightest handguards on the market. Our two piece barrel nut system and double locking quick disconnect system also creates an extremely rigid lockup.
