AR-15 Upper Receivers & Kits questions

What's the difference between a stripped receiver and an upper kit?

A stripped receiver is the bare upper receiver only, requiring you to source a barrel, BCG, handguard and charging handle separately. A complete upper kit includes the barrel and handguard already assembled together.

Do these fit any AR-15 lower?

These are mil-spec dimension components intended for standard AR-15 lower receivers. Confirm compatibility with your specific lower before ordering to avoid any fit issues during assembly.

What calibers are available in the complete kits?

Complete upper kits are offered in 5.56 NATO and 300BLK calibers, in both 7.5" and 16" barrel lengths depending on the specific listing you choose.

How fast do upper orders ship?

In-stock uppers ship within 24 hours of purchase, with free shipping over $99 and 30-day returns available on unused items that have not been installed.
