TruGlo TG8100B3 Tru-Tec Micro Shotgun Mounted Red Dot for Remington

If you want a compact red dot designed specifically for a Remington shotgun, the TruGlo TG8100B3 stands out for a simple reason. It is not just a micro optic by itself. It is a purpose-built Tru-Tec Micro sight and mount kit made for compatible drilled and tapped Remington receivers. That makes it a strong choice for shooters who want a cleaner setup, faster target acquisition, and a mounting solution that feels more direct than piecing everything together separately.

This model is a practical fit for hunters and shotgun owners who want a lightweight optic without adding unnecessary bulk. The compact profile helps keep the sight low on the receiver, while the micro design keeps the overall setup easy to carry and easy to handle.

Built for Remington Shotguns

One of the biggest reasons buyers look specifically for TG8100B3 is compatibility. This version is built around a Remington receiver mount, which makes it more relevant than a generic red dot for shooters who already know what platform they are working with.

Instead of searching through universal optics and separate mounting pieces, buyers can focus on a model designed for the job from the start.

This makes the optic especially appealing for shotgun owners who want a streamlined upgrade for hunting, range use, or faster sight alignment in the field.

Tru-Tec Micro Performance

The Tru-Tec Micro line is popular because it delivers the speed advantage of a red dot in a compact format that feels practical instead of oversized.

The TG8100B3 uses a 3 MOA dot and 1x magnification, allowing shooters to maintain a clear view of the target while keeping both eyes open. The optic window provides a clean sight picture that is easy to pick up when speed matters.

Because the optic is extremely lightweight, it works well on shotgun setups where balance and handling are still important.

For many buyers, that clarity is exactly what makes this model appealing.

Ideal Uses

The TG8100B3 is commonly chosen for:
