Rainier Arms

Rainier Arms started with a simple philosophy: if we won't use it, we won't sell it. That enthusiast mindset has made them one of the largest online sources for quality AR-15 and AR-10 rifles, parts, and accessories.

Complete and stripped uppers and lowers, barrels, high-end AR-15 grips and stocks, optics, suppressors, and gear from manufacturers including:

• •Glock (Gen 6 optic-ready pistols)
• •SIG Sauer
• •Smith & Wesson
• •Primary Arms
• •Stag Arms
• •PWS (Patriots Weapons Systems)
• •Rainier Arms house brand
• •Staccato pistols
• •Tippmann Arms

"Rainier Arms is my go-to dealer for high-end AR15 parts and accessories online. They always have a great selection of parts in stock. Many you can't find anywhere else."

Their inventory includes rare and specialized components that typical gun stores don't carry. They maintain competitive pricing with exclusive products and regular sales events like their Black November promotions.

Based in Auburn, WA (near Seattle), they operate a full retail location alongside their massive online operation. Local customers can order online and pick up in-store, combining the selection of a national dealer with the convenience of a neighborhood gun shop.

Rainier Arms publishes detailed blog content on industry trends, new releases (like the Glock Gen 6 launch), and contract awards affecting the market. They also offer gunsmithing services and maintain an FFL locator for customers managing transfers.
