The 990 Aftershock has an issue
The Mossberg 990 Aftershock is reviewed as a potential Short Barreled Shotgun (SBS) host, noted for its gas-operated action and compatibility with Magpul SGA stocks. However, the firearm exhibits significant reliability issues, particularly with lighter ammunition, due to a theorized weak extractor. Mechanical flaws like the M-LOK ratchet system backing out also detract from its performance.
