This micro red dot comes in at just 2.75 inches in length and 2.1 inches in total height (1.9 above the rail). The single red dot reticule is 3 MOA. The elevation and windage adjustments can be made with a flat head screwdriver in 1 MOA increments.
The base mounts on a 21mm Picatinny/Weaver rail with a screw through the middle. If you want to mount this on the more common dovetail grooves you’ll need to use a dovetail to picatinny adapter or riser. This will be necessary on the Diana Chaser, Airbug, Bandit, Crosman 13XX/2240 Steel Breech, etc. There are many cheap options out there. We have one here: https://buck-rail.com/product/dovetail-to-picatinny-adapter/
You can also mount it with an optional 1″ co-witness riser. If you’re not certain if you need the riser or not, just pay the extra $3 and set it aside if it turns out that you don’t. The risers will not be sold separately.
This Red Dot is compatible with our Crosman mounts. I prefer to use the single extended mount without the riser.
Included with your Red Dot will be a set of rubber dust covers, a battery, allen key, lens cleaning cloth, and some very Chinesey paper instructions.
Red dot is is not a crisp dot, it's fuzzy.
This is not an inexpensive Aimpoint.
I have a reflex site too, and it's tough to say which one I like better.
It's a little faster to aim when you use the reflex version, but I find it harder to know when the red dot is perfectly centered in the glass, so my accuracy is slightly better with this micro-red dot tube version.
I have gotten a few bad flyers which I've never had before with my Hw30s. I'm not sure if that was pellet related or optic related. I'll update this review when I figure it out!
