- Slightly narrower entrance for better sealing to achieve more uniform effect. - C-clip to improve rigidity for additional sealing - Special pressure point geometry reduces inconsistencies between shots for more predictable trajectory - Suitable for Marui / WE / KJ GBB pistols, WE GBBRs and VSR-10.
NOTE: Due to special pressure point geometry, this product is optimized for use with open-type hop-upinner raceways . (i.e. Marui original pistol inner barrels and the most compatible inner barrels)
