We have the tools, experience, and most importantly the refined attention to detail required to handle any repair or modification on the AR15/M4 platform. We aren’t a do-all shop where you can send in your 1911 or shotgun. This isn’t by necessity, but by choice. Trajectory Arms’ mission is to provide the best services for this platform that you can find anywhere in the industry.

In a time where the vast number of manufacturers are making components for the AR platform, tolerance stacking and improper quality control processes lead to failures right out of the box. Our inspection, repair, and modification processes allow us to find and fix these issues before any permanent modifications are done.

Our comprehensive Assembly and Inspection service includes everything to build your rifle correctly for peace of mind, or get your inefficient rifle back up and running to it’s highest standards. The inspection service comes with a full breakdown of what was checked and repaired. It also includes test firing and custom recommendations for each rifle. Any additional services will receive bundle discounts of up to 25% when combined with the Assembly and Inspection service.

Our shop is an excellent choice for the services you need to finish up your home build as well. We have collected the machinery, tools, and experience to perform these services for you, and send them back to your home bench : 

We strive to keep lead times as short as possible, but because of our policy of doing things right the first time, the timeline can vary and fluctuates weekly. You can email to get in contact with our shop manager for questions about current lead times.
