About
RAUCASUPPLY sells parts for people who build their own pistols and rifles.
We keep a short catalog of slide kits, rail kits, lower parts kits, and magazines for 9mm G17/G19-pattern pistols and AR-15 rifles. Each part is listed with the details a builder needs to order it right the first time: what it fits, what it's made of, and everything that comes in the box.
We ship within the United States. Buyers are responsible for knowing and following the laws where they live.
Fitment you can check
Every listing names the frames, generations, and patterns a part is built for. If a part only fits one design, the listing says so.
Complete kits
Kits include every pin, spring, and component the job calls for, and each product page lists exactly what's in the box.
Specs before checkout
Material, finish, caliber, and capacity are on the product page, so you know what you're ordering before it ships.
Not sure what fits?
Send us your frame or receiver and we'll point you to the right parts.
