The CZAR is a 3D printable receiver for use with Vz61 parts kits (32ACP). The CZAR uses AR15 fire control parts, which makes installation of the fire control parts much easier, increases the strength of the receiver, and allows use of the wide array of AR15 aftermarket triggers. Based on the FMDA Vz61 AR15 receiver, it is reinforced, comes with an optional top-rail equipped version, and a long list of dimensional tweaks that make is the easiest and most reliable Vz61 receiver print available (for 32ACP applications). Also included is a Vz61-style grip that mates up to AR15-based grip attachment points. This allows you to capture the iconic look (and ergonomics) of the original Vz61 without having to sacrifice the benefit of the AR15 fire control group. Shoutout to salo_ for the design of the grip!
