The Baby Barrett is a build that deserves a spot in everyone's safe.
3/5 scale from the real deal, chambered in 22LR, and includes options for both M82(pictured) and M107. This is a "99% printable" build, meaning everythings printed short of the nuts, bolts, springs, fire control group, and barrel/liner. You can use a barrel liner in 3 different lengths, or an RS22 barrel, 10-22 barrel, or Mossberg 702 barrel.
Like the other builds by Kaewon, you can expect an easy to print, easy to assemble, and true to form 22LR clone of one of the famous firearms that got us all into guns.

I always wanted to build one but as I understand it the bolt is based of the EZ 22 bolt. Ive never been able to get any build based off the ez22 bolt to properly chamber a round from any mag I tried. Did you have to do any fine tuning after you got everything assembled?
No more so than any other primarily printed build. Kaewon has also iterated on the bolt over time, adding things like the SCS bolt face and breach face and extractor.
Generally speaking on a build like this, you need to make sure the extractor moves freely, make sure there are no edges of the bolt face that will catch on the upper, file the feed ramp>liner smooth, and i usually knock off any sharp edge in the 12 oclock position that might catch a round while feeding..... basically make sure everything is smooth
I haven't personally built an ez22, but I've done 6 complete builds of kaewon's designs all of which were loosely based on that bolt
It's possible I could've over looked the instructions but I never saw any mention of an extractor. It seemed to be entirely dependent on blowback. Id been savin a proper ten inch barrel liner
Originally it was just blowback extraction. Extractor was added a bit over a year ago
