The 990 Aftershock has an issue
This review of the Mossberg 990 Aftershock, presented by Brass Facts, highlights its performance as a gas-operated, semi-automatic 12 Gauge shotgun. The analysis, conducted with high-round count stress testing, reveals significant reliability issues, particularly extraction failures, and a pickiness with ammunition. While compatible with some aftermarket parts like the Magpul SGA stock, it struggles with cheaper loads, making it less versatile than some competitors. The review emphasizes a critical, data-driven approach to understanding the firearm's limitations.
