The ADV TECH T3 Stock for Mossberg 990 is a modern, tactical shotgun stock built for hunters and shooters who want genuine ergonomic upgrades and practical features without the weight penalty. This aftershock-designed stock replaces the factory furniture on your Mossberg 990 with a modular platform that balances compact handling for transport and carry with shooting comfort and recoil management in the field.
The T3 incorporates Tactlite construction for durability and a TracLOCK Gen2 system that keeps components locked in place under use. The included X Series recoil-reducing pistol grip and X2 recoil-reducing butt pad work together to soften felt recoil, making follow-up shots faster and more accurate—especially valuable when you're hunting or running the gun hard at the range. An adjustable and removable cheekrest lets you dial in your sight picture whether you're running iron sights, a bead, or a mounted optic.
Practical features matter in the field: dual-sided QD sling attachment points let you configure your carry system however works best for your hunting setup. The overall design prioritizes function over fashion—this is a working shotgun stock for people who actually use their guns, not a safe queen piece.
