Build your own Quantum DTL rifle!

Platform designed by us; features selected by you. The Quantum DTL series features our patented Dual Taper Lock system. Every major component is manufactured in-house with painstaking attention to detail and the entire rifle is tuned for performance. We want you to be as proud to own it as we are to make it so here is your chance to tailor a Quantum series rifle to suit your style and needs. Choose your trigger shoe, barrel length, furniture, finishes, and more. What you are left with is a complete rifle you’ll want to shoot all day. And that’s money well spent.

Note: Our lower receiver features an ambidextrous bolt release. This is not a bolt catch.

Assault weapon ban (AWB) states: Pistols are not available for sale to banned/limited states.

NOTICE REGARDING CLEAR ANOCOAT RECEIVER SETS: We will make every effort to match your upper and lower receiver as close as possible, but 100% color match is not guaranteed.

Our 9” barrel features a 1:5 twist.
Our 13.9” barrel features a 1:7 twist.

Our .300 AAC (Blackout) barrel features our dedicated .30 caliber enhanced extension. This extension improves the reliability and cycling of multiple types of subsonic and supersonic .300 AAC ammunition, including hollow point.

For suppressed shooting, we recommend that you use a suppressor that is specifically compatible with the lower pressure of the .300 AAC cartridge. Please consult with the suppressor manufacturer for recommendations.

Our accuracy guarantee is based on testing without any suppressor.
