Question: cna o use this for a pistol crossbow
Document: I bought this sight to use on Crosman/Benjamin air guns. It mounts securely on both my .22 Discovery PCP and my steel-breech 2250 carbine from Crosman's "Custom Shop" converted to HPA (so recoil is not an issue). The unit is compact and lightweight on both guns and should even be suitable as a pistol scope as it has unlimited eye relief.Sighting in was simple and quick; the 1/2 MOA adjustment clicks were positive and easy to adjust with a coin or screwdriver.
I purchased this for a Crossman pump air pistol. It mounted easily onto 3/8 dovetail mounts and it appears to be pretty secure. I needed something I could use at close range (&#60;10m) in low light conditions where the iron sights wouldnt work well. This does the job admirably and I've had no problems shooting tight groupings under those conditions. Are there better &#34;red-dot&#34; sights? I'd guess so.
I bought it for my father's crossbow. He is very pleased with it and he uses it for deer hunting.
I haven't sighted this one in yet, but it appears to be a very nice piece for the price. Very clear and easy to use.
I'm glad for the color option as I actually find the green dot preferable to the red, especially in low-light environments.Does not have an "auto-off" feature but the battery is relatively common and so far the one that shipped in the unit has powered it for several cumulative hours. They also sent a spare.At $29.95 this is a great value for a simple dot sight, ideal for use on guns with integral 3/8ths dovetail mounting systems.
This little light weight red dot sight is a favorite. Bought it for my Ruger 10-22 but after seeing how well it works am going to get another one.
Put this on a pellet gun w/out iron sights that I was stupid enough to buy. It's a whole new gun. Great for plinking. Seller was great. Will do business with again.
It appears to be good build quality and a good value for the price.
I recently purchased this item,installed it yesterday and finally got to sight it in today..with 5 shots had it dead on at 20 yards. Amazing.. Very easy to install and operate..I would highly recommend this item to anyone !
I had hoped it was a 2 MOA dot as advertised but it's not - it's the same size as other 5 MOA dot sights I have, which is too big in my opinion.Nevertheless it works well, allowing me to consistently get 3/4&#34; groups or less at 12 yards, zeroing in a springer air rifle. Windage and elevation adjustments require a normal screwdriver, unlike some units that allow fingers-only adjustment.
Answer: yes
