ATI Ammunition
The ADV TECH S-FLD STK MOSS 990 AFTRSHK is a side-folding stock purpose-built for the Mossberg 990 shotgun and compatible models. This is a tactical upgrade for shooters who need a compact, maneuverable platform—whether you're running a home-defense build, competition setup, or specialized shotgun application. The left-side fold design saves real estate when you need it, and the adjustable cheek rest lets you dial in your sight picture for optics or iron sights.
Build quality matters on a stock, and ATI's precise manufacturing keeps this component running hard without flex or rattle. The TactLite Gen2 design pairs a six-position adjustable length of pull with the brand's TracLOCK system, so you can lock your preferred fit and not worry about accidental shifts during shooting or movement. Dual QD attachment points give you multiple ways to sling your shotgun, and the thoughtful engineering eliminates snag points that can catch on gear or create handling delays.
If your Mossberg 990 is your primary shotgun and you're looking to optimize it for tactical handling, accuracy, or pure practicality, this stock replaces the factory profile with something genuinely configurable. The removable and adjustable cheek rest is a real asset if you run an optic or shoot from positions that demand consistency.
