DIY can be rewarding, but some steps deserve a bench. Spartan Arms is happy to coach what’s safe at home—basic cleaning, screw checks, sight picture habits—and what to leave to a jig, press, or mill. We’ll install and level optics, set torque, thread barrels, and complete pin/weld where needed, then document the work for future service.
