[ARCHIVED THREAD] - Why I think you should mill your rear iron in front of your red dot (Page 1 of 2)

This question seems to come up a lot. This is why I think you should put Irons in front of your RMR (in order of priority to me): - Puts the RMR further away from the ejection port and RMR window is partially eclipsed by the rear sight, both of which result in elimination of carbon and lube buildup on the glass. After hundreds of rounds my RMR window is still minty fresh instead of carbon frosted like my buddies gun (m&p). This can be more or less of an issue depending on how dirty or clean the ammo you shoot is - RMR further back means I didn't have to cut or re-purchase any new holsters to fit the RMR. Given I have about $300 dollars in Glock 19 holsters, this was a good thing - The RMR window isn't very big, and having the irons to the rear eats up some of the bottom of the window. At least with irons in front, the dot can be superimposed so the full window is usable - While I dont beat up my RMR, irons forward provide some protection to the optic body if you cycle the gun off a hard surface - At least with Glocks, you can mill slightly deeper, putting the dot a smidge lower. As far as the reduced sight radius, I can still shoot head shots at 25 Y on IPSC target, so I don't find that to be an issue. The only real downside is that you're committing to keep an optic on as it would look funny with only a cover plate on

I agree with you OP and should be sending mine off to get milled here soon. Just need to decide on who’s going to do the work.

| That's a great deal. Got mine done with them and couldn't be happier. |

I got a good deal on a used ATOM slide, or else I’d probably go this route. Thanks for the heads up and have a great 4th

@johnconnor you get it done? eta: nm. Saw you got atom slide. Throw some pics up

I will play the Devil’s Advocate...
I know a lot or people may not like him but Gabe knows how handle a gun and was doing RDS on pistols before it was cool. The rear sights should be behind the rear dot. |

The rear sights should be behind the rear dot. His main point is that if you change where the irons are, you have to relearn your muscle memory. This doesn't make sense. You have to relearn anyways for a red dot and you shouldn't be looking at the irons anyways. |

You have to relearn anyways for a red dot and you shouldn't be looking at the irons anyways. Also, with most holsters if they are not cut to take an RMR they may not fit with the rear sight in front either. I have no concerns about my RMR needing protection from shell casings as I never had shells hit my RMR. The RMR window is big enough that I don’t have any issues with the rear sight covering the dot and I also have no desire to mill the slide so that the dot sits lower. Hey, everyone can do what works best for them. There’s no one way... |
 I have never seen that before.

| Interesting idea but is it adjustable? |

No, neither are any of the other RMR compatible sights. Maybe it’s just me, but I like to dial in my rear sights so they are centered properly. |

Quoted: Having the rear sight behind the RMR works really well for me. I used my supressor height sights to train my RDS draw stroke. No, I don't use both sights together but it sped up my ability to pick up the dot. Also, with most holsters if they are not cut to take an RMR they may not fit with the rear sight in front either.

Im just busting your chops a bit. I built muscle memory for the dot to be in the center of the window. For this to occur the front sight post is higher than rear sight instead of being level. It's a (slightly) new sight picture. Conversely - you'll notice if you aim with the irons, the dot should be located below the top of front sight post. They are two independent sighting systems at different aiming planes. It's easy to switch between them but they are different. |

@joshaston
I missed this. Pretty clever. Do they offer this with Torx screws? |
|
I use a Crye precision gun clip to holster my G19 while suppressed. It would not work with a front mounted iron sight. Otherwise, I agree with every one of your statements. I hate the carbon buildup shooting suppressed. After 300 rounds you can’t even see through the window. |

What is the ideal dot size to go with for a pistol? |
|
Quoted: Depends on who you talk to. Most guys with a USPSA type background advocate a larger dot (around 6-8 MOA) while the 1 MOA RMRs are the latest fad on the tactical side. For me, I've found the 2.5-3.25 sized dots work the best. I like 2.5 - 3.25 as well. |

| I've never used a pistol with irons in front of the RMR (yet), but I did own a Caracal pre-recall with their "quick-sights" or whatever they were called; basically the rear sight was flush with the FRONT of the ejection port, and the front sight was in the usual location. It was fast and easy, and I really enjoyed shooting it. I never tried it past 10 yards, but it seemed fine for that and was noticeable faster than regular irons for me. Seems to me that sticking the rear sight in front of the optic would have similar benefits for speed/intuitiveness. |

Forward irons using the full window (dot over rear). Dot would be blocked if irons were behind optic. Attached File |

On a piece of electronics that have no guarantee of being on when I acquire my sight picture, I still grab my irons first, because I know they will always be there. Are you sure?

If I remember he said 8-10 weeks
Closer to 8 if you are getting plain black DLC and not a fancy color or pattern The nice thing about the AOS is the ability to swap plates for $20 for any changes or new optics... figured if I hated sights forward (which I doubt) I could easily swap too |
