SJ Manufacturing
Precision firearms
components, made in-house.
We design and manufacture the parts that keep proven platforms running — engineered, machined, and assembled under one roof in Canada.
The doctrine
Combat · Competition · Defense
01
Combat
Components built to run when it matters — duty, defense, and hard use.
02
Competition
Repeatable, tuned performance for shooters who count every fraction.
03
Defense
Dependable internals for the platforms agencies and citizens trust.
Why SJ
Vertically integrated
Engineering, machining, finishing, and assembly happen in the same facility. That control means consistent tolerances, steady supply, and a short path from a field problem to a manufactured solution.
