This service is temporary closed. This will give our team the opportunity to finish all current work orders. Once the current books are empty, we will open them again for a limited amount of work orders at a time. This should help us provide a better turnaround time for this service, as we will be able to finish every batch completely before we start another. You can join the waitlist to be added to the next batch and we will contact you when the service is available. Feel free to email us at email@example.com with any questions.
Barrels can be cut and threaded to a standard length or a custom length to match your rail or muzzle device.
We always indicate the barrels off of the bore rather than the outside and check thread concentricity, thread class, and suppressor alignment after the cut to ensure it was done right.
We can open up the gas port to your specification or we can recommend one for you based on the configuration and your intended use. There is no extra charge for this and we can make recommendations based on previous builds whether you are running a suppressor or not and what kind of ammo you run.
As with every modification service we offer, our cut and thread service comes with a free, 17-point inspection of the barrel before any permanent modifications are done. This includes things like checking headspace, gas port size, muzzle and throat erosion, etc. An inspection sheet detailing these checks and any measurements taken will be returned with your barrel and if we catch any issues we will discuss them with you before taking any action.
The price is for a stripped barrel, however if you need us to handle assembly and disassembly there is an extra charge of one hour of gunsmithing, or consider combining it with our Assembly and inspection service for 25% off. This discount applies to any value added barrel services like pin and weld or gas block pinning.
Now offering barrel cut and thread on more than just the AR platform! If you don’t see your gun in the list below, contact us to see if its something we can do!
Select your barrel type as well as if you want a muzzle device pinned and welded on a 14.5 barrel or 13.7 barrel (Save $20) or gas block pinned (Save $10) on any AR-15 barrel.

Trajectory Arms is the only place local that I would trust. Hell, even with guys I would ship to; I like keeping my money in the community and supporting local shops. I brought in an 11.5, asked for a 10.3, and got a 10.3. Gas port size confirmed, and a couple pieces of advice as I brought him a used upper assembly I got for a steal. Well worth it!

Shipped my MCX Virtus barrel to them to have my barrel cut to 13.7. Amazing service all around! Kept me posted throughout the entire process, turnaround time was fast and quality is outstanding! I’d absolutely trust them with any of them my firearms! 10/10 would recommend!

I sent my barrel in for cut/ thread and pin/weld at the recommendation of a friend who knows the people here at Trajectory. I am not disappointed in the slightest at the quality of work! Phenomenal. I will say that the level of customer service absolutely blew me away though! Some of the easiest and quickest communication I’ve had with a company. A lot of companies don’t understand customer service these days and how crucial it is for a customer to return and recommend their business. Not Trajectory! I will be recommending them for services to anyone who asks me. Thank you guys for being some of the ones who still value your customers!
