Accu-Bite Super BCAR - OFD Hana Version

The Accu-Bite Super BCAR - Hana is a 3D Printed muzzle device specifically for the Hana toy foam dart blaster from OldFusionDesigns. It requires 3 3x7x3mm flange bearings and 3 m3x12mm screws.

The Accu-Bite Super BCAR was inspired by the work of Misplaced Moose and his “Moose-Bite Super BCAR”. The Accu-Bite utilizes a single row (3) of F683ZZ Flanged Ball Bearings, secured with 3 m3x12mm screws. The bearings are installed at an angle that gives them each 2 points of contact with the dart as it passes through. After the dart passes through the bearings, it enters a PCAR portion of the barrel which constrains the dart's flight path to help correct rotational drift as the dart exits the muzzle.

The Accu-Bite was designed around HvZ level velocities (~120fps) and has its bearings at a 13 degree angle. This has not been tested with higher FPS setups. I have added a 9.5 degree version which should be better for higher FPS setups, but this has not been tested.

REQUIRED HARDWARE:

3 x F683ZZ Flanged Ball Bearings (3x7x3mm) - https://a.co/d/0gYmB4ab

3 x 12mm screw (10mm should also work) - https://a.co/d/0bPcz8H5

ASSEMBLY:

- Place a dart inside the Accu-Bite - Body. This will keep the bearings from falling through their holes during assembly. - Place a bearing inside its slot with the flanged side towards the smaller hole for the screw (see picture below). - Drive an m3x12mm screw through the hole aligned with the places bearing. The screw goes into the “big hole”, and the threads will catch after it passes through the bearing. Tighten the screw until you feel resistance and the head of the screw is below the rim of the hole. - Repeat steps 2 & 3 for the other 2 bearings/screws.

INSTALLATION:

Just like any other Hana Muzzle for a short/flush barrel (~120mm), simply thread the Super BCAR into the front of the Hana until it is snug to the barrel. For Hana's with extended barrels (minimum of 18mm exposed), use the standard version of the Accu-Bite Super BCAR.
