In-House Barrel Fluting
Want to save time and avoid sending your barrel to multiple shops?
We can flute your barrel in-house as part of the process. Add fluting to your barrel while we have it in the shop and keep the entire project moving through one location.

Trevor (verified owner) –
All of my Straight Jacket chambered barrels flat shoot. I have always had good communication with the team regarding caliber, twist rate, barrel length. No headspace issues, just load up ammo and shoot. I gave Straight Jacket a chance after multiple bad experiences with another gunsmith. I now have a safe full of Straight Jacket chambered and even built rifles.
John M –
Super fast turn around! By far the best machine work I had encountered in the industry. I have have had barrels cut by all the big names in the long range shooting shops and SJA is definitely doing something different. Thanks
Darren Medley (verified owner) –
Great turnaround, great communication on helping decide what reamer would be best for my application. The barrel shoots better than I could have imagined. Second barrel I’ve had cut by SJA and definitely not the last.
Anthony C. Miller –
Certainly, did not disappoint this barrel turned right on my receiver and shot great. I will be in touch when I do my next build. Great guys to work with.

Appreciate ya buddy!
Aaron (verified owner) –
They answer the phone and answer your questions. Accurately quoted lead times. Well packaged shipping. Chamber and threads cut straight. My handloads in this 6.5CM CRB barrel shoot .2-.4 MOA 5 shot groups. This is a recreational gun and it is performing as I expected.
Christine Miller (store manager) –
Thank you Aaron, we really appreciate you taking the time to share this. It means a lot that our team answered your calls, met lead-time expectations, and shipped everything securely. Hearing your 6.5CM CRB handloads are shooting .2–.4 MOA makes our day. We’re proud the chambering and threads performed to spec, and glad the rifle is delivering exactly what you wanted for recreational shooting. If you need anything else — accessories, maintenance tips, or another build — we’re here to help.

I got an 18” 22GT cut and it shoots amazing. I wasn’t a fan of some of the selectable options on the webpage, so I called up LaWayne and he got me lined out with exactly what I was looking for. I wanted mine shouldered to the barrel extension on a medium Palma profile and a 1:8” twist. I am in love with my Sig Cross now, I always thought it was the ideal truck gun but didn’t like the 6.5 CM for coyotes. Now that I have it in the best .224 cartridge designed, and shooting sub 1/2” groups with 62gr ELD-VT at ≈3350fps, I take it with me everywhere. Just need to work a load with 80gr ELD-X for deer and antelope now.
Christine Miller (store manager) –
Thank you for taking the time to leave such a detailed review. We’re glad to hear your 18” 22GT is shooting so well and that it transformed your Sig Cross into exactly what you wanted. LaWayne takes pride in helping customers dial in the right specs, and we’re happy he could get you set up with the correct profile and twist. Sub-½ MOA performance like that is always great to hear. We appreciate your trust in Straight Jacket Armory and wish you the best of luck as you work up that 80gr load for deer and antelope

My .308 win barrel is top workmanship. It shoots 10 shot 1/2” groups with single sd’s. I did no load development or brake in. Great work guys!
Christine Miller (store manager) –
Thank you for sharing this, we really appreciate it. That’s great performance right out of the gate, especially with no load development or break-in. That’s exactly what we aim for. We put a lot of focus into our chambering and finish so shooters can see results like this from day one.
