Quantum Mark 2
See all reviews | Questions (0)

The Quantum Mark 2 is the perfect blend of performance and aesthetics. When an aerospace company that is obsessed with design and tolerances creates an AR-style rifle from scratch, you better believe it will perform.

Every major component of the Quantum Mark 2 is manufactured in-house with painstaking attention to detail. Because of this we can ensure perfect fitment, providing the ultimate end result without regard to loose tolerances found acceptable by other manufacturers.

The entire rifle is tuned for performance. We want you to be as proud to own it as we are to make it. All you have to do is give it a try and you’ll be hooked.

The Quantum Mark 2 feels as good as it shoots. All edges are deburred by hand, and our finishing process delivers a rifle so smooth you won’t want to put it down. What you are left with is a complete rifle you’ll want to shoot all day. And that’s money well spent.

At this time we do not ship this rifle to California, Connecticut, Maryland, Massachusetts, New Jersey, or New York. Any online orders to these states will be canceled and refunded.

Orders to Colorado, Hawaii, Illinois, and Vermont are shipped with magazines compliant to local laws.


The Quantum series lower receivers are equipped with our patented Presslock™ technology. The Linear Compression Pad ensures a tight, rattle free fitment, essentially "bedding" the upper and lower receiver together while eliminating carrier tilt.

Zero™ Short Reset Trigger

Dead Air Silencers® KeyMount Muzzle Brake

Our 13.9" barrel Quantum Mark 2's come with a pinned and welded Dead Air Silencers muzzle brake. This makes 16" barrel length, while providing you with an excellent brake that's ready for your silencer.

Performance barrel

The Performance Series barrels start with premium 416-R stainless steel bars that are gun-drilled and reamed at standard production speeds in 5R rifling and 1:8 twist. The blanks are then fully stress relieved and precision air gauged before profiling, threading, and chambering begins.

Our barrel profile features strategically placed linear expansion rings that control the heat growth of the barrel during heavy use. These unique design features, coupled with our adherence to improved machining tolerance standards, result in straighter bores, a superior finish, and improved accuracy.
