Please leave a like and rating and consider posting a make if you print and enjoy the design - it really helps me out! The BMBCAR is designed to be the ultimate printable super BCAR for high powered nerf springer or AEG/AEB blasters, in terms of performance, ease of printing and assembly, and ease of use. Support me by purchasing a hardware kit from my store. Hardware kits include custom screws specifically designed for 3D printed BCARs. Affordable international shipping available. Also check out my other products including blaster hardware kits at my store! Fit to the Zinc .50 blaster for the ultimate accurate nerf hand cannon (see 2nd image). Zinc .50 hardware kits available here (must select the 205mm barrel option to make the passthrough barrel configuration which allows fitting external BCARs such as this one). 'Full length' variant has 6 rows of 3 bearings with a total length of 177.0mm. 'Compact' variant has 5 rows of 3 bearings with a total length of 154.0mm. Both have the exact same vented PCAR segment and use the same collet part. Designed to fit 16.0mm OD barrels, with 39mm of barrel protrusion required. See the images for the print and assembly guide. All features - Designed from scratch to be the ultimate 3D-printable super BCAR.

- Fully 3D-printable with zero supports or brims - designed for clean bridging over the bearing wells.

- Super BCAR accuracy: vented PCAR rifling segment followed by staged 3 x 5/6 BCAR segment for best in the business foam dart accuracy.

- Robust and durable design for use on the skirmish field.

- Strong and solid attachment area to ensure straightness with the barrel.

- Quick-lock collet - quick and easy tightening and no printed collet threads.

- Captive snap-on collet design means the collet always stays with the BMBCAR, even when fully loosened.

- Printable tool included in the files for more leverage to tighten or loosen the collet. Shouldn't typically be needed, but useful if it needs to be tightened more for example on an anodised barrel which is more slippery compared to raw aluminium, or to loosen it if it has gotten stuck and is unable to be loosened by hand.
