BCAR for Orion Blasters Lynx v2

I remixed the “ex” bearing centering and rifling device to integrate with the Lynx by Orion Blasters. It slots over a 45cm barrel and is secured with the standard front pin and a 10mm m3 button head screw and a heat set insert in the front to prevent it from rotating. I have decided to include the 12.6x6 model as, through my limited testing, I can conclude it is the best angle and diameter for a blaster hitting between 180 and 240 fps. I recommend printing at a 0.2mm layer height and 25% infill with 4 outer perimeters while ensuring the part of the model that holds the bearings is sticking straight up when printing. This makes cleanup easier and makes sure the rough part of the model that touched the support isn't visible.

For cleanup, make sure to remove all support materials, especially from where the screws and bearings sit.

After cleanup, installing the bearings isn't terribly difficult, but can be tedious. The way I recommend installing them is as follows. (I advise doing this while the part is not attached to the blaster) Apply a tiny amount of superglue or clear nail polish to the tip of a screw and screw it in a few turns. (This prevents the screws from backing out when you are using the blaster) Insert your pinky finger into the front of the bcar and place the bearing in so that the flange is on the side closest to the head of the screw. (Your finger prevents the bearing from falling all the way through the model) Screw the screw in the rest of the way.

In order to install this modification, remove the front rail of the blaster and drill a 4mm or 5/32 in. hole. you can find the hole's location by first printing this model, installing it, then marking on the front rail where the top hole in the model aligns with. Sink the heat set insert into the front rail slightly past flush with the flat face and trim away excess plastic that flows over the top. Then, slide the bcar over the tip of the barrel and re-insert the front pin. (you might have to brace the stock against the floor and push on the top of the bcar while inserting the pin depending on the spacers you have installed in the blaster) The last step is to screw in the last m3 screw into the heat set insert.
