Meta Tactical MX-1 Conversion Kit for Glock – Polymer Stock (MX1-PSTK)
The Meta Tactical MX-1 is an all-in-one conversion chassis that turns a Glock pistol into a compact, shoulder-fired carbine-style platform. This is the Polymer Stock (PSTK) version with a folding full-length polymer shoulder stock, available in Black, Grey, OD Green and Tan. It suits shooters who want more stability, a cheek weld and rail space for optics and accessories without buying a second firearm.
- One chassis for Glock Gen 3/4/5 pistols (see model list below)
- Folding polymer shoulder stock with steel-reinforced core; folded it fits in a backpack
- AR-style charging handle for smooth, consistent operation
- Patented tool-free locking system: the pistol is inserted and secured without tools
- Aircraft-grade aluminium top rail and shroud on a lightweight polymer body
- Full-length Picatinny top rail, Picatinny bottom rail and M-LOK side slots for optics, lights, grips and spare-magazine holders
- All 7 beavertail adapters included to match the pistol frame
No barrel is included: the pistol keeps its own slide and barrel (Meta Tactical’s longer barrels are sold separately). Fits Glock 17, 19, 19X, 20, 21, 22, 23, 26, 27, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 43, 44, 45 and 47 in Gen 3/4/5 (incl. MOS and SF versions as listed by the manufacturer). Glock Gen 6 (17, 19, 45) requires the separate Glock Gen 6 Expansion Pack. NOT compatible with Glock Gen 1/2, Glock 40, 41, 42, 43X, 48, 17L, 18, 24, or pistols with suppressor-height sights, slide-mounted red dots, beavertail backstraps, barrel-mounted compensators or extended slide stops. A shoulder stock changes a pistol’s legal classification in many countries; check national legislation before fitting. Made in USA.
