Question: Will this fit a picatinny rail?
Document: Fit my rifle with ease. Small and just what I would recomeed to anyone who is looking for one. Great price too.
I purchased this for my stainless Ruger 10/22 because I didn't want, or need, a large &#34;tactical&#34; style sighting device, but wanted to move up one step over the basic factory iron sights and keep the budget simple. Mounted it on the Ruger rail supplied with the rifle and went to the range.
This scope shipped very quickly. I know guns but not super well and this is a gift. If it doesn't turn out well I'll update but it looks great so hopefully it works as well as it looks!
This is a nice, low cost red-dot scope. I have it on a .22 rifle and it has stayed zero'ed for me just fine. It's no Aimpoint or Eotech, but it also costs a lot less than those excellent optics. I also liked the peace of mind buying a scope from a well known, quality brand that costs the same as cheap Chinese knock-off.
That said it took a few rounds to get it close, and about 20 more to zero it in. The best grouping I had was a 10 shot 1&#34; group at 30 yards with Federal Target bulk ammo. This is as good as my 4X scoped rifle and before this it was a challenge for me to get the Ruger to shoot any real consistent groups with assorted ammo and the factory sights. It held similar groups of Remington, Winchester and CCI, all bulk ammo.
So, overall, I liked it better.
Received the unit. Turned it on, saw the red dot. Tried the brightness levels. Got distracted, set down on desk while it was still turned on. Returned a couple hours later and found it dark. Fiddled around with dials but it wouldn't work. Assumed dead battery, I changed it. Still no go. Tried 2 more fresh batteries to be sure, but the unit just wouldn't work. Returned it. Infant death I guess. Ended up spending more but got a Bushnell TRS-25.
Not too shabby of a red dot, its larger brother with a 30mm lens is alot easier to see thru, this is the compact one, very small but very bright dot!
Next stop will be out doors with some 35-50 yard shooting. I have had very good results with Simmons scopes which is why I went with their Red Dot. This is the first budget Red Dot I have purchased.
It is what it is. A cheap red dot. I have mine on a m&p 15-22. I had to add a riser to use the scope comfortably. I am shooting dime - quarter size groups at 25 yards. It was sighted in one magazine(25). I'm satisfied overall. I would not pay more than 30 dollars for it though. I also had better luck with the retical on the lowest power setting.
Answer: yes
