Reduced weight without compromise
With the Promethium TL-1 our goal was to create a lightweight, portable rifle without sacrificing accuracy or performance. To achieve this, we started by making a few changes to the largest and heaviest components in a rifle: the chassis, action, and barrel. For the chassis, we selected the XLR Carbon because of its excellent balance of ergonomics, durability, and weight reduction. We then incorporated an extremely tough titanium action body and paired it with a fluted steel bolt to create the ultimate rifle action. Finally, we designed a special 18-22 inch* custom profile barrel specifically for the rifle to achieve an optimum balance between accuracy and weight savings. What we ended up with is a 9.65lb* rifle that’s durable enough to perform in the harshest conditions, and still carries our standard ½ MOA or better accuracy guarantee with appropriate ammunition.
Superior portability and ergonomics
With an overall length of only 36.5-39.5 inches, and weighing in at just 9.65 lbs, the Promethium provides a level of mobility that’s more reminiscent of an assault rifle than the precision rifle that it is. As a result, many nonconventional shooting positions that would be difficult with most other rifles are far more achievable with the Promethium. To push the Promethium’s strengths in unorthodox shooting positions even farther, it comes standard with a long, 15.5 inch carbon fiber free-float handguard that provides greater flexibility for stabilizing the rifle while shooting. This handguard also incorporates the M-LokTM mounting system providing a practically unlimited number of accessory mounting options. Flexible ergonomics are also critical to ensure the rifle can be comfortably used in any position, by any shooter; so we equipped the Promethium with a fully adjustable stock, an oversized bolt knob, and a formed, hand-filling pistol grip. The Promethium’s stock also folds, allowing the overall length to be reduced to a mere 28.8" inches for easier transportation.
We didn’t just stop at making an uncompromising lightweight rifle; we kept working to make the Promethium the best rifle possible. For the action, this meant hand fitting, and coating the bolt in DLC (diamond-like carbon), a coating with an extremely low friction coefficient and diamond-like hardness that ensures smooth bolt cycling, easier cleaning, and reduced wear. The action also has a faster lock time to help reduce the impact of any movement introduced into the rifle during a shot. A great rifle is nothing without a good trigger, so we equip the Promethium with either a 3lb single stage, or 2.5lb two stage trigger from Timney. This highly-regarded manufacturer has been making some of the best triggers around since 1946. For recoil management, the Promethium is equipped with a Griffin Armament Paladin break. This two chamber break is compatible with Griffin’s line of excellent suppressors, and features their special taper mount system which helps ensure accurate suppressor alignment. To top it all off, each Promethium gets one-of-a-kind Cerakote paint job in the color and pattern of your choice.

A faster lock time (2.3 milliseconds 11.5% faster than standard 700 style actions) and lighter strike (4.3 in/lbs) produces less disruption to the rifle when firing.
18” 5C Rifled Barrel
Barrels are crafted Broughton blanks made from 416R Stainless Steel. They are pull button rifled and stress relieved five times throughout the production process. Then each barrel is hand lapped with a uniform land and groove diameter up to 0.0001" from breech to muzzle.
5C rifling (Canted Lands) provides higher muzzle velocities, increased bore hardness, and extended barrel life. Rifling twist rate varies with cartridge and caliber selection.
Available in either 3lb single stage, or 2.5lb two stage configurations.
Every Timney trigger is made from a solid block of heat treated steel, so there's no connector bar to come loose.
Additionally, each trigger comes with a trigger blocking safety, meaning there's no way to move the trigger when it's on safe.
