ARHK has entered full production.
We have completed testing on all platforms (MP5, MP5K, G3/91, 11, 21, 23, 33, 51, 53, and 93) and everything is functioning great and held up to our torture testing.
We anticipate that our first drop of 1500 units will be in roughly 8 weeks and those will all be ready to ship at the time of the drop.

The answer was the ARC-fire by @ASDesignsFRTs ..
This thing just runs. Go buy one, or 20.
You can now find the Geissele jig on our Odysee!

Our MP5 hammer rounding jig for Geissele is here: odysee.com/@ASDesigns:a/Geis…
(The Leber V2 rounding jig works fine for milspec hammers)
Can confirm, MR762 (M110A1 clone) runs with ARC-Fire and a mil-spec AR FCG. Stock BCG, nothing special.

Geissele trigger cutting guide for ARC-Fire mainly but this will also work with the super safety. The top left slide is very important for ARC users.
Time to keep your pinky out B&T boys 🧐
Super Safe APC45 & APC9
This is a lower kit we have in development at Active Safety Designs. This design does not require the upper to be milled.
