Aimpoints or Red Dots

[gregdr01]

I've been using optics a long time, and for me the best reticle of all the available options is the ACSS Vulcan in green (green provides better clarity, especially for those with astigmatism). This reticle is available on several Holosun models, and one of my favorites is the "K" (smaller size) version of their 507 model -- attached photo shows the HS507K-X2 ACSS Vulcan on my 617, which is an awesome setup.

Generally, Holosun provides the best combination of quality and price -- along with exclusivity of the ACSS Vulcan reticle (which is shared only with a few Primary Arms optics).

The 507K ACSS Vulcan is about $300.

Specific to the Mk IV, I have a 22/45 variant upon which I've installed an Aimpoint T-2. If you're going with a (color) red optic, Aimpoint's are the most "crisp," although Trijicon is a close second. Either of these offer dots which are better defined -- and remain so, even after punishing recoil of a 500 S&W -- although on a 22LR it could be argued there's little need for a "super tough" optic. Still, I chose to go with the T-2 because I was tired of being disappointed in the sloppy dots from other optics. Sure, a Holosun would have been a good choice, but not as good as the Aimpoint (and by some margin).

The T-2 is $600+... does it make sense having an optic that cost more than the gun upon which it sits? All I will say is try one, and then decide for yourself. For me, my Mk IV 22/45 is upgraded with Volquartsen and TandemKross parts, and having the the best optic known to mankind was worth it.

Too much fun!

I have switched over from red dots to green dots. I found the green dots to be more sun resistant.

OK, so I am looking at the info on the olight SE, but I cannot see how it would mount to a rail? I admit that I am dumb as a stone on this stuff

 

[Rodan]

It looks like the Osight SE is an RMSc/407k footprint... two screws through the sight from the top, directly into the slide/mounting plate. The slide/mounting plate must be milled/drilled/tapped for that footprint. Note that it is different from the standard RMR/Holosun footprint.... usually used for smaller/compact guns.

For a direct to Mk4 mount, you need something like this.

For a pic rail, it will require a rail mount for that footprint... like this. This type of mounting will increase the height.

So what is wrong with increasing the height, not enough adjustment in the device itself? It will always shoot high?

 

[Rodan]

Most prefer to keep the sight axis as close as possible to the bore axis, and it also keeps things more compact, but it's really not a deal breaker on a range gun.

When I make new red dot mounts, for the MKIV Stainless, this is what I'll make.
Low profile, as close as possible to the OEM irons.
Not concerned with co-witness for punching paper.

Here ya go.

LowPro™ Low-Profile RMSc Red Dot Mount for Ruger Mark I/II/III/IV

The LowPro™ Low-Profile RMSc Red Dot Mount for Ruger Mark I/II/III/IV pistols is an ultra-low-profile mounting plate for attaching a red dot with an RMSc footprint directly to the barrel of a Ruger Mark I/II/III/IV.

www.lowpromounts.com

Install this mount to the top of the gun. Your Ruger must be drilled and tapped for a mount.

Then install the red dot to the mount. Use blue loctite.

The Osight comes with several different screws with different thread pitch and length.

Easier than you think.

That one is nylon.

Low Profile Red-Dot Mount, Ruger Mark Series RMSc

Please Read Compatibility Notice Below! Our low profile mount for Ruger MARK series pistols allows the end user to mount a Red Dot Optic directly to the frame of the pistol. This allows for a much lower bore axis vs. picatinny rail/mount stack up and has been designed for a clean integrated look...

This one is aluminum. I would buy this one.

Can’t remember who makes this mount but it’s been working great. SRO has a nice big window too.

* Farrow Tech as mentioned above

Very cool, Octagun!

Check the X and 10 ring diameter, on the B6 and B2 pistol targets.
Seems like a 2 or 3.25 dot might work.
Not sure about a 100 yard target.

Have read that tube red dots, Aimpoint, is often used for Bullseye.
Heavy, is the only negative.

 

[Imissedagain]

Have also read, that the Aimpoint dot, followed by the Trijicon dot, are clear and crisp, compared to others.

 

[minconrevo]

Those that use red dot pistol scopes professionally (LE) most commonly run one of the newer cube type, such as an Aimpoint ACCRO P-2. For the average user, something along the line of the Holosun 407 Shake Awake 3 MOA red dot will do fine. This particular one is a Palmetto State Armory exclusive. It fits on the common RMR base. Adapters are available to take it to fit on a 1913 rail.

You will rue the day you buy a really cheap red dot. They fail quickly. They eat through batteries. They won't hold zero.

I’m a little slow getting into the 21st Century and mostly go for big orange or green dot front sights. But… I bought a Shield SMSc for a G43x several years back. Didn’t work with it much cause I couldn’t stand the gun it was mounted in. I’ve since picked up an Sig 365XL cut for red dot but haven’t got that far yet. Nothing else in my collection has the slide cut. Anyway, good advice and varying opinions, but from my observations, Trijicon or Holosun are two I’d look at. They seem to have the best street reputation. For a rimfire, it may not matter as much, but I’d still lean toward one of either.

Here is my compact Israeli JERICHO CZ-75 clone. Ordinarily I don't care for rails & coated finishes - BUT I WON IT (new) in a dealers sweepstakes. Jericho's are actually Italian TANGFOLIO CZ-75 clones - Improved by the Israeli IWI ,
I was surprised by its quality, & took advantage of the rail - to mount a powerful Mini Green Laser, + use extended Mags.
Finding that it can be fired accurately from the hip with 2 hands, using the laser sight - it is now my "go-to" for things that go bump in the night. Green lasers will work in sunlight as well. I don't really like other "Gun-Warts" on handguns..
Surprised I like this so well. IT is heavy enough to minimize recoil as well.

Get that optic mounted on the P365XL... pretty sure you'll like it. I tried the G48/43 before buying a P365 and the Sig shoots a LOT softer. With the optic it's a very capable carry piece.
