Question: Does it have multiple brightness settings?
Document: The brightness is good enough to shoot on sunny days. The included flip up caps are a plus in my book. But if any old red dot will do for you, there are better ones out there for very similar prices.
worst thing anyone could pay for, if it was free would still be to much. it cant keep zeroed in even on a BB gun. DO NOT BUY.!!! !
works great.good value for the money. no not want to talk any more but have to, to finish this teview.
this is really nice look, works very well not much to zero in, the red/green dot is bright and clear. I would buy this product again
looks real great mounted on the crossman pellet rifle M-4, a little dificult to zero it but it's a great sight
We originally purchased this sight as a low cost option for a .223 caliber rifle. We knew from the beginning that it may not work out. After playing around with it, we determined it was a better fit for .22 cal rifle (such as the 10/22 Tactical variants) or an airsoft gun. Mounting and zeroing it was not a problem, but it is a low cost sight and long term durability on a rifle was in question.
This will probably hold up just fine on rifles chambered for intermediate rifle rounds.It may not survive battle rifle rounds.It DEFINITELY was not meant to be mounted on a slug gun. Found that one out the hard way.
This sight was delivered the first week of March and was installed and used the same day. It has been almost 2 months now and the sight has seen use every couple of days on my son's Crosman M4-177 air rifle. His air rifle has standard Picatinny Rails and this sight fits fine. This sight works great on his air rifle. Was easy to sight in and has held the zero so far.
This scope does everything I need to do. It provides a way to sight for someone that t a poor shooter, is cheep, and easy to install
This reflex sight works well on my AR-15 rifle and was simple to install. I bore sighted the rifle after installation and this was alsosimple to do. I highly recommend these Centerpoint Reflex Sight Products for any rifle of shotgun installation.
