I put it on the Arex in mid-January, so about four months ago. And I like it!
I was really shy about spending the money, it retails for more than the pistol does, but I’ve found no reason to regret it.
There’s a couple of varieties of RMR and I got the one with a 3.25 MOA dot and no buttons at all. It automatically adjusts the dot brightness, there’s no way to manually influence it, and I was a little concerned about how it would deal with bright desert sun. It has no trouble with it at all, and even at full power there’s not the slightest bit of bloom. It’s very small and light, does one thing, does it very well, and doesn’t move on to the next thing because there is no next thing. It seems a little silly that such a simple little thing can cost so much money and I’d never put one on a range toy but for an every-day pistol that’s gonna get knocked around it’s absolutely great.
I’ve been trying to work on my speed on my little dueling tree and kept missing high, so today I put up a paper target to check the RMR’s zero. And at 20 yards…
…there’s clearly nothing wrong with the zero. That one flyer was all me. I can shoot faster with a good red dot, and with careful aiming I can also shoot more precisely with one than I ever could with iron sights. And a good one was what the Arex – or probably any other everyday-carry gun I have in future – really needed. Maybe a Holosun would have done as well? I have had one on my rifle with no complaints for years – but I don’t drag the rifle around on my belt through all conditions all day every day. So I’m not sorry I spent the money.
Red dots are good for accuracy.
You made the right choice. Red dot sights have come a very long way in reliability that only a fool wouldn’t use one on any firearm. I even have on one my little Churchill over and under with a short twelve-inch barrel. And yes, I’m in Canada where shotguns with barrels as short as nine inches are perfectly legal with no tax stamp or other BS.
