Product Description
Riptide Rails is proud to announce the Maelstrom Pro, a delayed blowback upper for the Mac-11 platform and its variants. The Maelstrom Pro is a bearing-delayed blowback upper designed to modernize and elevate the Mac-11 platform. By moving away from the traditional straight-blowback system, this upper softens the recoil impulse and mitigates bolt bounce, resulting in a flatter, smoother, and more controlled shooting experience.
Designed with both aesthetics and high-performance engineering in mind, the Maelstrom Pro features a user-serviceable, sealed bearing detent delay system, a monolithic picatinny rail, and a non-reciprocating, folding charging handle. It is compatible with standard OEM Mac-11 lowers (and variants) and "full-size" Mac-11/MPA30 9mm bolts. Uppers will come assembled and ready to use.
