Alta Arms: Home Of Precision Firearms And The Ace Of Spades Magazines
Alta Arms is a family-owned firearms manufacturer based in Coeur d’Alene, Idaho, specializing in custom precision firearms and American-made components. Founded by a competitive shooter, the company focuses on accuracy, reliability, and performance that holds up in real shooting conditions. As the creator of the Ace of Spades 15-round rimfire magazine, Alta Arms builds firearms and components that shooters trust when consistency matters.
Custom Rifle Builds
Every rifle build starts with purpose. Alta Arms designs and builds custom firearms and precision rifles tailored to the shooter, the discipline, and the end goal. From action selection and custom chambering to barrel work, trigger tuning, optics mounting, and final setup, each build focuses on repeatable accuracy and long-term reliability. These are not shelf builds. These firearms are carefully machined, assembled, and tested to perform under pressure, such as during competitive shooting.

Barrels & Chambering
Proper barrel work and chambering are critical to accuracy. Alta Arms provides precision barrel fitting and custom chambering using exact measurements and proven machining methods. Each chamber is cut to match the intended cartridge, pressure, and performance goals. The result is consistent feeding, clean extraction, and repeatable accuracy.

Barrel Threading
Alta Arms offers precise barrel threading for muzzle devices such as brakes and suppressors. Threads are cut concentric to the bore to ensure proper alignment and safe, consistent performance. This service helps reduce recoil, improve control, and protect accuracy. Clean threads, proper timing, and careful inspection are standard on every job, giving shooters confidence when adding or changing muzzle devices.

Experience makes the difference.
Troubleshooting and Tuning Done by Someone Who Competes
Many shooters come in with firearms that should perform better, but do not. Accuracy drops, feeding feels inconsistent, recoil behaves unpredictably, or the setup just does not feel right. These issues are often subtle and easy to overlook if you do not spend time shooting under real conditions.
Jessiah is a competitive shooter who understands these challenges because he has faced them himself. He knows how firearms behave when timing, balance, or tolerances are off. That experience allows him to identify problems quickly and apply precise tuning and machine work that actually improves performance.

“Easiest mag to set up and consistently feeds with no issues. Best mag out there.”
“I had been looking for a high-quality magazine for my RimX when I stumbled across these. The ease of adjustment is amazing! I had an issue that required some reworking to fit my stock, and the entire Alta Arms family was absolutely wonderful. They quickly figured out the problem, and now it runs flawlessly. When I say family, that’s truly what I mean—this product was developed by one family that genuinely makes shooters’ needs and satisfaction its number-one priority. Thank you all! Buy with confidence.”
“I bought an Alta Arms magazine for my RimX, and it’s now my favorite. From loading and feeding to fit and finish, everything works beautifully. The easily adjustable magazine catch makes setup simple. Great magazine!”
“With so many choices in rifle chassis, this is the only choice you need for a rimfire magazine. The ability to fine-tune the catch to your latch system ensures perfect round presentation and reliable loading every time. The machining and craftsmanship are outstanding, and the customer service is exceptional!”
“Absolutely the best magazine I’ve ever used for any gun! The Alta Arms Ace of Spades is the easiest-loading and smoothest-feeding magazine for any firearm I own. The quality, craftsmanship, and feel in the hand are unmatched. The adjustable magazine catch is rock-solid and easily adjusted to fit any gun or chassis system. This is an item that just plain works!”
“I wish I had bought these magazines sooner! If you’re on the fence, just buy them! I finally bought a pair at the NRL22 Nationals, and I absolutely love them!”
“I met the Alta Arms crew at the PRS22 Rimfire Championship in Idaho last year. I’m always looking for spare magazines for my Vudoo, and these guys knocked it out of the park with this magazine! It was super easy to tune for my chassis and feeds perfectly in my rifle, which I very seldom clean. I give it five stars!”
“Smoothest-running rimfire magazine on the market! It’s easy to fit to any chassis, and it’s the only magazine I use for AICS rimfire. A great product with unmatched reliability and quality!”
“Love these magazines! I was so tired of extension magazines that required tuning and adjusting. These magazines just work, and they are built solidly. I definitely recommend buying them and am always telling others in the community about them. Great magazines!”
"The Ace of Spades magazine has been a game changer for my daughter. Before we found these, she struggled with other magazines at every match. With just the magazine change, she was able to increase her score at each match by at least five impacts because she was no longer struggling with feeding issues. Alta Arms is a wonderful family business, and its products flat-out perform!"
“Alta Arms rebuilt my rifle from the chamber up, and the difference was immediate. Groups tightened, feeding issues disappeared, and the rifle finally felt right. Jessiah actually listened to how I shoot and built around that—I absolutely loved it!”
“I took them to two matches and put a few hundred rounds through them without a single issue. The setup was simple, and the feeding stayed consistent even in cold, damp conditions.”
“The Ace of Spades 15-round rimfire magazine is rock-solid. Feeding is smooth, the fit is perfect, and it holds up through long-range days. You can tell it was designed by someone who actually shoots.”
“What sets Alta Arms apart is the attention to performance details that most people miss. The tuning work they did completely changed how my rifle feels and shoots. Communication was easy, questions were answered quickly, and the end result was exactly what I was hoping for. I would not hesitate to trust them again.”
“I’ve been shooting competitive matches for several years, and working with Alta Arms has been one of the best decisions I’ve made. Jessiah understands how rifles behave under match pressure, not just on a bench. My rifle runs clean, stays consistent, and gives me confidence every time I step on the line. That matters more than anything.”
“Today’s match was another solid win. The rifle performed, and the magazine kept pace the whole time. Everything cycled cleanly and predictably.”
