My NGRS MP5 sneaky slut. I love this gun, shoots so well and works so flawlessly. Waiting on a longer VFC claw mount rail to move the optics back a little. 3D printed tail cap to fit the ICS folding stock, Prometheus barrel with 4uantum bucking + nub, M100 spring. I think it's right around 1j on 0.28s, sufficient for me.
Has a very "functional" pressure switch arrangement for the X400 clone, but i like it. The short rail section was machined to match the radius of the silencer, and a small screw is used to index it into the correct position.
