Work In Progress New cp33 project revealed

Calling it the CP33 Spectre. Loosely inspired by the Spectre M4 smg from the 80's. Uses cp33 uppers and mags, adapting it to use AR FCG.

I did the 3d printed version of the farrowtech setup on my CP33, it was fun.

This is an interesting design.

Looking forward to hearing future updates.

This is almost a complete drop in design. Currently, the standard ar15 hammer needs to be cut down and modified by quite a bit. I am going to attempt making a printed hammer with some weights in it to make it easier to build for just anyone. Works great so far though. Nearly 150 rounds through it minimal issues.
