Baby Barrett Hardware Kit

Update 9/12/24: Baby Barrett backorders have all shipped. We are back in stock with the standard bolt (no extractor) while the extractor gets tested. Upgrade kits to extractor bolt will be made available once testing is complete, at which point this kit will also switch over to using the extractor bolt.

The Baby Barrett is an AR based, 22 caliber, 3/5 scale Barrett clone. Finally, you can afford to own and shoot a Barrett…some assembly required.

This kit includes all hardware required, regardless of the variant you chose to print. This means depending on which variant, you might have a few extra nuts and bolts. Most of this hardware is readily available and I link to it below. Please make sure you are using current files when assembling this build, as the files on Odysee have been updated multiple times. In the updated files, there is a modified bolt designed to accommodate the tungsten powder for bolt weight. Older versions of the files may not include this modified bolt. Additionally there are updates to the files for RS22 barrel, which now accommodate the non-threaded version as well

There are 5 barrel options for this build:

BYOB – $69.99 – No barrel included. This assumes you will be cutting and chambering your own barrel liner, or sourcing an RS22 barrel directly.  Get one here!

15.5″ Liner $120 – A 15.5″ cut and chambered barrel liner will be included(you must permanently affix muzzle break to ensure this still meets rifle length)

18.75″ Liner $130 – An 18.75″ cut and chambered barrel liner will be included – Medium Length

21″ Liner $145 – A 21″ cut and chambered barrel liner will be included – Long Length

RS22 – $159.99 – Includes a NON-Threaded RS22 barrel.

Parts that are NOT included, but you will need to complete the kit:

A standard AR-15 Lower parts kit (specifically FCG, Springs, mag release, and safety)

All of the printed plastic pieces (no printed plastic is included in this kit)

A few things you should know before buying this kit:

This is a hardware kit for a 3d printed gun. No plastic pieces are included, and no parts of this kit are regulated items.

Please be aware, I’m just a guy in my garage, not a full blown machine shop. Some fitting may still be required.
