Ruger MK I/II/II Standard and 22/45 Super Pack - Open Beta

Open Beta for my work improving IMA and PixelSmoke's MK Series work that was abandoned in Beta. No build guide yet, you should be familiar with making barrels from liners for the monopiece receiver. I've also included Spinn360's Threaded receiver for use with an OEM barrel and shims for fine tuning it. LBRY Tags: 3d printing; ruger; mk series; 22/45; stl
