After scouring the sea for Ruger MK models, I’ve blended a few together. NotaGuntuber had a MKIV step that I flat-topped, added the barrel plug from DB’s MKCarbon jig and the MarkR by Pixel_Smoke/Insertmeow barrel shroud. Just got the barrel put together today. Function test hopefully this week if it’s not too frozen outside. Once I get this fine-tuned, I’ll drop the step, SolidWorks and STLs on the sea.
EDIT: I forgot to add that the grip frame is a MKIV 22/45 that I picked up from Wirthwein. Will be modeling that using the Kilo v2 version as the base.
So for this particular build, I have the Ruger 22/45 frame, Ruger bolt and printed pull ring, printed receiver, barrel plug, carbon fiber tube and the 22lr barrel liner inside that tube, stock Ruger magazine and printed 22/45 base plate.


Isn’t this cheap to build too?
Depends. Bolts are about $20-30. Frame internals are about $35-45 (MKIV). Finding MKIII and older internals is expensive as there seems to be only Volquartsen etc available.
My biggest hang up has been finding a grip frame assembly that ain’t almost as much as a new MkIV. Could someone point me to a decently priced option?
Unfortunately, there isn’t one yet.
