Specna Arms ONE BBs offer superior quality and innovation, expanding the brand's BB range with professional grade ammunition. The ONE BBs are designed for optimal performance in standard and precision barrels, and post-production processes such as a high-gloss polish and a special coating to lower friction with Hop-Up bucking give them superior performance. The round shape and lack of imperfections ensure highly repeatable shots, while a 5.95mm diameter and weight variations of less than 0.01g provide compatibility with both standard and precision barrels.
