Here’s a pretty good deal on a micro red dot and quick detach riser mount combo on Amazon.com. While it’s no Aimpoint, it would make a great budget red dot for a range weapon or plinking rifle. The reviews are mostly positive for them. They’re currently selling for $33.95 with free shipping on Amazon.
– Reticle Type:Red Dot
– Color:Matte Black
– Magnification:1x
– Mode:QD Micro
– Rail Type:20mm Weaver rail
Great for shooting out to 100 yards, or farther if your target is large, and the integrated Weaver-style mount works on any Weaver-style and most Picatinny bases.
