Welcome To
Straight Jacket

We are a family owned shop based in Evanston, Wy. This shop was built with the idea that customer service, and customer communication should, and always will be paramount!

Welcome to Straight Jacket Armory!

We have quickly become the industry leader and place to go for Pre-fit rifle barrels and Barrelled actions! While we still produce some of the best Lightweight Carbon fiber pack rifles and Tactical rifles, the last 2 years have really steered us to the Pre-fit barrel market, and Barrelled actions.

We Are also offering an amazing Long Range Hunting 2-day course this summer! (click “classes at the top of your screen) We cover everything from gun safety, to set up and pushing our students to shoot out to 1 mile! (1760 yards)  on our Private Range that boasts over 3,000 acres of shooting fun right here in Evanston Wyoming!

We started offering Pre-fit barrels for a handful of action companies back in 2018. Build a solid top-ranking Pre-fit barrel and the rest is history as they say! Find out what thousands of shooters already know and click on the pre-fit barrel link to start your order today!

Our Pre-fit barrels start by using ONLY match-grade top-name blanks by Benchmark, Bartlein, and Proof research. This is one of the biggest reasons our barrels are priced where they are and perform as they do!

Our Pre-fit barrels are CNC cut and hand-inspected to ensure the proper fit and exceptional accuracy

We offer Pre-Fit barrels for the following actions:

Big Horn/ Zermatt Arms TL3 Origin and SR3

Kelbly’s Atlas Tactical

Curtis Custom Axiom, Valor, Vector, and Helix actions

Impact Precision 737 and 787

Lone peak Fusion and Razor actions

Defiance Machine Ruckus, Tenacity, Anti, and Anti X actions

American Rifle Company Nucules, Archimedes, and Mausingfield actions

Terminus Zeus, Apollo, Kratos actions

Accuracy International AT AX, actions (short action small tennon)

At this time, we only offer Pre-fit barrels in a “shouldered” configuration, this means no barrel nuts, and no setting headspace and lash by the consumer. All the specs are precisely held in-house so no mistakes can be made at home.

At this time we are not offering Prefit barrels for Savage or Tikka

We Are also listed with Hornady as one of just a handful of companies making both Carbon Fiber and Stainless steel match-grade Prefit barrels for the 7PRC. All of our rifles and barreled actions are now available in the 7 PRC also!
