BUSHNELL AR TRS-25 3 MOA 25mm Red Dot Sights (AR731306)

The TRS-25 is a great red dot sight, approximately the size of other popular micro-dot sights, competing against offerings from Holosun, Vortex, Primary Arms and Aimpoint. Although the Bushnell is often the least expensive of all of these sights, it's definitely not low quality. Buyers should be aware that the transmitter will be visible through the optic, and the lens is a little tinted - however, Bushnell is upfront about both of these nuances, and they won't hinder you at all from using this sight. This particular model comes with a riser that makes it perfect to attach to an AR and co-witness with iron sights.

Cheap and effective. What else can you want?

This red dot is well built, small, and solid! It will be hard to find something better for the money. Liked it so much I picked up a second.
