Rainier barrels are meticulously designed and machined by precision gunsmiths. Our barrels are turned the same way true artisans have made premium rifle barrels for over a century. Each barrel has hand-cut chambers and crowns with the attention to detail that can only come from highly trained human intervention. While most companies strive for faster production time to cut costs, we strive for perfection. There are no shortcuts with our barrels, period.
We will go toe to toe with anyone and win.
Satisfaction Guarantee We are so confident in our barrels that we offer a 100% money back guarantee within 90 days of purchase. If our barrels don’t meet or exceed your expectations, for any reason, return it for a full refund.
Many have asked us to build a barrel with the same workmanship as our Match barrels while keeping it more affordable. We are able to reach our goal by sourcing a very high end barrel blank at an affordable price. We start off using a high precision match blank in 1:7 twist, use a 5 groove polygonal rifling, machine it to the highest quality and matched with our limited-life time warranty, you have a barrel that is the best value, hands down, in the industry.

i recently bought this for a 300 blk backpack gun. the quality was what i expected, but what really surprised me was how accurate it is. now im not a great shooter but during my zeroing session it would consistently put .5-.75 inch groups at 50 yards and 1.5 inch groups at 100, with cheap (at least for 300 blk) ammo. for a 6.5 inch barrel im very ...Read MoreRead more about i recently bought this for a 300 blk

Review by Bruce S. on 5 Aug 2021review stating Proprietary gas tube not included
Totally excited to build a shorty, but it is a proprietary gas tube about an inch shorter than pistol. Now I have a paperweight until I can find a tube. Should be a great barrel once up and running.
Review by Errongun on 29 Aug 2020review stating Great little barrel
Got this barrel wanting to build a shorter suppressed upper. It has not been a disappointment at all. Im getting 2000fps with 110s, 1915 with 125s, 1848 with 135s and 1648 with 155s. Accuracy with 110s was/is better than my ability with 4moa red dot at 50 yrds around an inch easily. The only negative is it’s dirty due to shorter gas length but tha...Read MoreRead more about Got this barrel wanting to build a
t’s expected as all suppressed guns are filthy. Im very happy and pleasantly surprised with both velocities and the accuracy. I have shot and owned 16,14.5,10.5,9,8 and now 6.5in blackouts so this is not a biased review. Read LessRead less about Got this barrel wanting to build a
Q: How is the length of 6.5" measured? Is it the actual overall length from end to end?

A: Barrel length is measured to the ATF standard method of bolt face to the crown. The external length of the barrel will be around a half in longer than the rated length.

Q: Will this shoot subsonic rounds? If not can you recommend the right barrel. I want the shortest barrel that can shoot subsonic suppressed.

A: That will depend on the rest of your parts. Please contact our technical department by phone to discuss your specific build.
