Mossberg
590A1 M-LOK 18.5" 6+1 BLK
Item # MB 50766 MSRP $770.00PRODUCT DETAILS
TECH SPECS:
Built to the demanding MIL-SPEC 3443G standard, the Mossberg 590A1 M-LOK (Model 50766) delivers proven, duty-grade performance in a rugged pump-action shotgun that’s equally well-suited for home defense, duty use, or tactical applications. Constructed with a heavy-walled 18.5″ barrel and finished in a durable black Parkerized coating, this 12 gauge offers 6+1 capacity and reliable performance round after round.
The standout feature on this model is the M-LOK-compatible forend, allowing quick attachment of accessories like lights, lasers, and grips to meet mission-specific needs without permanent mods. Standard Mossberg engineering — including dual extractors, positive steel-to-steel lockup, twin action bars, anti-jam elevator, and a top-mounted ambidextrous safety — ensures smooth, dependable cycling under stress.
Finished with a black synthetic stock and bead sight for intuitive target acquisition, the 590A1 M-LOK combines classic Mossberg reliability with modern modular flexibility. Whether staged for personal protection or duty carry, this shotgun stands ready wherever rugged performance counts.

Ask a QuestionProven Arms & Outfitters A bolt-action rifle requires the shooter to manually operate a bolt to load a round, eject the spent casing, and chamber the next round. In contrast, a semi-automatic rifle is designed to automatically eject the spent casing and chamber a new round with each pull of the trigger. Semi-automatic rifles offer faster follow-up shots, while bolt-action rifles are typically more accurate due to their design.
