The ABF-8 (Auto Buckfoam) Go to product viewer dialog for this item.
—often colloquially discussed in hobby circles alongside its predecessor, the ABF-7, and its community nickname “CD Blaster” due to its large, round, disc-like internal 3D-printed flywheel setup—is considered a massive game changer for the high-performance DIY Nerf and foam-blasting hobby.
Designed by community creators as an open-source project, it completely shifts how hobbyists think about heavy-hitting, multi-dart “shotgun” coverage.
The primary reasons the ABF series has fundamentally disrupted the community center on accessibility, mechanic styling, and tactical supremacy: 1. High-End Power for the “Everyday Builder”
Before this design emerged, high-performance, mag-fed auto-shotguns (like Project 16 or the Rail Cleaner) required complex, expensive, and intimidating brushless motor systems with custom programming. The ABF series flipped the script by using standard, highly accessible 20.4mm 130-180 brushed DC motors and a generic 35mm solenoid. It effectively democratized full-auto foam shotguns, allowing average hobbyists who are intimidated by brushless electronics to build their own powerhouse. 2. Devastating Horizontal Spread
The blaster feeds from specialized P16 magazines to fire multi-dart clusters at a time. By utilizing widened, non-concave 20mm gap flywheel configurations, it propels a wide, horizontally biased spread of foam. Within its effective 30-to-40-foot range, this horizontal wall of darts makes it incredibly difficult for opponents to dodge, even if they try to duck behind skinny cover. 3. Open-Source Modularity
Because the creator released the files publicly on platforms like Printables, it has become a playground for community upgrades. Within days of its release, the community began adapting it with customized parts including: FAL-style cosmetic handguards
BCAR Shrouds (Bearing Rifling Attachments) for fine-tuning the dart spin and spread Improved iron sights and custom magwell plates 4. Flawless Full-Auto Solenoid Cycling
The inclusion of a heavy-duty 35mm solenoid allows the blaster to switch between semi-auto and full-auto seamlessly. While its cyclic rate of fire sits at a reliable 240 RPM (rounds per minute) / 4 darts per second, each “round” is actually a massive cluster of darts. This lets players suppress a hallway or choke-point with absolute authority.
