The RIP-MAC V2 is our refined take on the original Twitch concept, built for Masterpiece Arms / clone MAC-10/11 platforms. Precision cut from 316 stainless steel, it offers excellent durability, corrosion resistance, and long service life.
The V2 update focuses on aesthetic improvements and weight reduction only — there is no change to function or operation compared to OUR previous version.
Due to platform differences, minor fitting may be required. Some OG MAC variants can be made compatible with proper modification. If unsure on fitment, we recommend testing with the PLA+ version first.
