***VERY IMPORTANT! Must use the correct bolt lengths for the charging handle or the bolt interface will break! Correct sizes are: 8-32x1.25" for the front bolt that interfaces with the cmmg bolt, and 8-32x0.5" for the rear bolt.***

The second iteration of the Tubee-22. This is a side charghing upper receiver, designed to be printed threads down like the previous Tubee. This upper can work with all standard mil-spec AR15 parts, or you can print the Tubee-22 lower and use it with this V2 upper. The STEP file contains some extra goodies like a folding stock and brace that uses 25x23mm carbon fiber tube that gets bonded to the printed parts using epoxy and a new style handguard that matches the contour of the V2 nicely. Note that these parts have minimal testing which is why they are only in the STEP. The side charging handle is designed to use a bolt that goes through it and reinforces the bolt interface to prevent it from breaking. This worked extremely well in testing.
