ATI Outdoors Shotgun Magazine Clamp – 12 Gauge, DuPont Zytel Polymer, Black (Model SMC1100 | UPC: 758152511003)
Upgrade your shotgun setup with the ATI Outdoors Shotgun Mag Clamp (SMC1100) — a lightweight, durable, and secure mounting solution designed for 12-gauge shotguns. Constructed from high-strength DuPont Zytel polymer, this magazine clamp delivers rock-solid stability without the added weight of traditional metal clamps. Whether you’re enhancing your home defense firearm, building a tactical rig, or optimizing a hunting setup, ATI’s mag clamp ensures your accessories stay tight, aligned, and mission-ready in any condition.
Precision Design for 12-Gauge Shotguns
The ATI SMC1100 is engineered specifically for 12-gauge shotguns and designed to connect the barrel and magazine tube securely. This precision-fit clamp keeps your barrel and mag tube aligned, improving stability and overall balance while reducing vibration during shooting. It’s the perfect upgrade for maintaining structural integrity after installing an extended magazine tube, tactical light mount, or other barrel-mounted accessories.
High-Strength DuPont Zytel Polymer Construction
Unlike traditional metal clamps that can rust, corrode, or add unnecessary weight, the SMC1100 is made from DuPont Zytel, a reinforced glass-filled polymer known for its strength, resilience, and weather resistance. This advanced material provides superior impact resistance and long-term durability while remaining lightweight and maintenance-free.
The non-marring polymer surface also protects your shotgun’s finish from scratches or wear, ensuring both durability and aesthetics are preserved.
Lightweight and Corrosion-Resistant
The ATI Shotgun Mag Clamp is built to handle all environments — from humid marshlands to dry desert terrain. Its polymer design resists rust, corrosion, and chemical exposure, making it ideal for hunting, tactical, or marine use. You get all the stability of a traditional metal clamp without the drawbacks of weight or corrosion.
At the same time, the clamp’s minimalistic profile adds no unnecessary bulk, ensuring your shotgun maintains excellent handling characteristics.
Enhanced Stability and Accessory Support
When used with an extended magazine tube or barrel-mounted rail, the ATI Mag Clamp helps reduce movement and vibration under recoil. This ensures your accessories — such as lights, lasers, or sling mounts — remain firmly in place, even during rapid fire.
Many shooters pair the SMC1100 with ATI’s Shotgun Mag Extension Kit for a seamless, durable, and high-performance upgrade that delivers both form and function.
Quick and Simple Installation
The ATI SMC1100 is designed for easy installation with no gunsmithing required. Simply align the clamp over your shotgun’s barrel and magazine tube, then tighten for a secure, precise fit. The streamlined design ensures compatibility with most standard 12-gauge shotguns, offering universal fitment across popular models such as Remington, Mossberg, Benelli, and Winchester.
Its user-friendly design makes it a go-to choice for both seasoned gunsmiths and DIY firearm enthusiasts.
