The Sillybutts Excalibur is a pump-action spring-powered blaster that combines the compatibility of Captain Slug's Caliburn with the improvements of Silly's earlier Alchemist. Featuring a buttery smooth bearing-assisted prime and quickly-swappable full-length springs, this blaster is satisfying to fire at virtually every performance level. Additionally, its long dart magwell and optional wide barrel chamber make the Excalibur one of the best, most versatile blasters for beginners with existing darts and mags.
