Bradley Phillips discusses the 3L J330 Full Metal Bolt Action NERF Rifle, capable of reaching 300fps. Constructed from full CNC-machined aluminum, it features a true bolt-action mechanism with numbered bolts, a light trigger despite its spring load, and compatibility with Worker Talon magazines using a thick pusher. The rifle also boasts a threaded barrel compatible with C330, J330, Harrier, Seagull, and GLynx attachments, and achieves an FPS range of 150-300+ through its spring and barrel combination.
