The most accurate barrel on the market

Here's how we do it

Reduced Barrel Whip

By pressure fitting a thin-walled machine tube onto a barrel core, and then filling the void with our proprietary media, the resulting new monolithic structure adds accuracy-enhancing rigidity.

Drastically Reduced Heat

The greatest enemy to accuracy is heat. Our barrels reduce heat caused by firing, keeping the internal chamber and bore temperature very low.

Extended Barrel Life

By reducing heat and controlling the pressure wave throughout the barrel, we are able to dramatically extend the life of the barrel.

The DRACOS StraightJacket® Barrel System


The bullet never lies. When it comes to performance, the DRACOS StraightJacket® barrel is the most advanced lightweight composite barrel in the world. Through innovation and science, we are delivering a technology with one purpose in mind… unparalleled accuracy and barrel life.

To back up our claim, we offer a 100% money back guarantee and an industry standard LIMITED LIFETIME WARRANTY on the barrel for defects in material or manufacturing. The warranty covers functionality issues. This does not cover cosmetic blemishes, standard wear and tear or damage due to mishandling.

Dracos Barrels are proud to manufacture extremely high-quality rifles and rifle barrels that are absolutely capable of Sub-MOA accuracy. However, we do not offer a guarantee of accuracy due to the many factors affecting accuracy that include, but are not limited to: optics, shooting platform, environmental conditions, maintenance, shooter skill, trigger, and ammunition.

Dracos Barrels recommend using high quality factory new brass cased match grade ammunition such as: Federal Gold Medal Match, Black Hills Match, PRIME Ammunition, or similar.

Please reach out to for suppressor recommendations. Failure to use suppressors that are not compatible with Dracos Barrels will void the warranty.

In an independent test by H.P. White Labs, 390 rounds were fired in 3 minutes and 40 seconds. After testing was complete, temperature testing was done on the chamber and muzzle ends. With ambient temperature being 65 degrees Fahrenheit, the barrel was a mere 207 degrees Fahrenheit at chamber and muzzle. Existing military data says a conventional barrel would be over 1500 degrees Fahrenheit after the same test.
