ABOUT HARMS ARMS SUPPLY

Based in Cincinnati, OH, Harms Arms Supply is a family-run small business focused on quality firearms parts, accessories, and upgrades. 

We started in 2015 with the goal of providing fellow Americans with quality parts, accessories, and gear at affordable prices. That is still true today. Most of what we carry is for the everyday rifles and pistols our customers carry and use — parts, accessories, and upgrades built to be used, not just displayed. Reliability comes first, but we also believe your gun should look great. That’s why we carry a wide selection of Cerakoted and laser-etched products. 

Custom work is a core part of the shop. We offer professionally Cerakoted and laser-etched magazines and firearms accessories so your gear can match the rest of the build, or stand out on its own. From color-matched PMAGs to engraved designs, we treat custom magazines and accessories as functional upgrades, not just decoration. 

Most products we carry are made in the USA. We keep prices tight, ship fast, and stock the magazines, furniture, and upgrade parts people actually look for. 

We also sell in person at local gun shows in the Cincinnati area. If you want to handle the gear, talk through a laser job, or pick something up the same day, come find our table. Contact us for questions or more info.
