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.
The frame at the moment is stock Ruger MKIV 22/45. I'll be going over the model in Kilo's version as it's 22/45 style, but for MKIII and older. I plan to convert it to a MKIV.
That's awesome. My only hangup on making kilos is how large the receiver is.
