These are printed barrels compatible with CMMG, RTB, and PSA dedicated 22lr AR bolts and Redman's barrel liners. I have not live fire tested these, but have tested for feeding and extraction.
Included in the STEP are 4.5, 6, and 9 inch versions. There are also modeled in supports that break away with minimal effort.
*** This is an untested design and is posted more as a work in progress for anyone to iterate on ***

So the cost will really vary based on what sort of barrel you decide to use. AR22 barrels are more difficult to fine and will run you the most, generally $100+ and you might have to buy a dedicated 22 barrel collar to go with your kit. 556 barrels with the conversion collar that's that included with the CMM…

Yes 22lr dedicated builds I'm working on... SG22 and things of the nature that accept AR barrels. Want to print a barrel with 1/2×28 threads and put a liner in it.

Dang. Is yours a conversion or dedicated 22lr barrel/collar. Supposedly, the dedicated barrels run better.
