Accu-Nub 2.0 PCAR

The Accu-Nub 2.0 PCAR builds on its successor, the Accu-Nub. This is an entirely 3D Printed muzzle device for toy foam dart blasters with a minimum 18mm of exposed barrel (~16mm OD).

The 2.0 reduces the part count from 3 to 2 by swapping the OFD style collet system for a compliant clamping mechanism inspired by the work of Chance. This eliminates the finicky collet insert print of the original Accu-Nub.

INSTALLATION:

NOTES: I recommend installing the Sleeve off of the barrel and twisting it back and forth and removing and replacing it from the Body a few times to wear in the interfacing surfaces a bit for a smoother operation. You can also combine steps 1-3 on most barrels and insert the barrel through both parts together.

Additionally: When not installed on a barrel, you can twist the Sleeve all the way past the compliant clamps and it will stay together. This is great for keeping the parts together while not in use; simply twist in the opposite direction to “unlock” them again.

1. Slip the Clamp Sleeve onto your barrel
2. Insert the end of the barrel into the Accu-Nub 2.0 - Body until it bottoms out against the barrel.
3. Slide the Clamp Sleeve up over the Accu-Nub 2.0 body until it is flush, keeping the internal tabs on the sleeve aligned with the slots on the body.
4. While holding the Body, give the Clamp Sleeve a slight turn clockwise to engage the compliant clamps.
