I am just waiting on CAA to make an MCK for the Dagger and the Rock. I have Springfield, Glock and Taurus versions. If you don’t have one, you are really missing out. Made in USA, in FL, and they work so well. The Glock version can handle all manner of suppressors, comps, etc. It is like having a carbine that runs like your best pistol. They also do regular buy one get one sales events, similar to PSA.

PSA must be slammed with Christmas orders and possibly employees taking holiday time off. I ordered an RK1 slide on Dec 21 and it still hasn’t shipped.
Update:
I attempted to contact Customer Service and received an automated e mail response that due to the holidays, shipping times for all items are up to 15 business days.

My RK1 Slide shipped today, Yay.
Luckily I have another Holosun 507K X2 I had mounted on my FN Five Seven Mk 2 with the DT CAOS Slide Cover but the Holosun sat too high on the slide with the way the mount was designed and I just could not find the red dot instinctively.
On the Rock, I find it immediately.

Just received my RK1 slide & mounted my Holosun 507K-X2 RDS. I have discovered that the installed Ameriglo 1/3 Lower Cowitness sights do not cowitness with the Holosun either as absolute or 1/3 lower. The dot actually sits about halfway up the front sight when centered in the window. It appears that the sights are designed to cowitness with an RDS that is mounted on one of the adapter plates and not one that is mounted directly to the slide.

Interesting, these ones go absolute with my 407K X2. The mounted blade height is about 7/16". What does yours measure? Has the dot been zeroed?

Something caught my eye though when looking at the picture of these though. Tell me if I’m wrong… On the rear sight doesn’t the left dot look smaller and off center?

Its the way the picture is taken.

I did a double check on mine… Must be the picture angle.

The blade height on the RK1 is about .315 using my digital calipers which also seem to give an absolute co witness sight height of .215. I ordered a replacement Truglo Specialty Glock Front Sight Blade in that height and will see how that works.
My red dot is zeroed perfectly using a site-lite laser bore sight.

I’m confused, your blade height is lower and yet your dot is presenting even lower. Here’s a pic of this setup. Dobyou mind posting some pics?


That one with the dot was hard to take.

The front sight is .315 high. The rear sight is ,335 high.
Here is a photo. Getting it was just as difficult for me as it was for you.

How far out did you zero with the laser bore site? Did you have the front sight removed when you zeroed the dot?

Red Dot zeroed at 25 yds. Front sight was on.

I’m sorry for all the questions, I’m just trying to help. Free had zeroed @ 25 yds or stabilized? If your dot is behind the blade wouldn’t the laser spot be as well? TBH I wholeheartedly agree with the 25 yd zero!

Free hand only. I slightly tilted the pistol up so I could see the laser and the red dot without any attempt to co witness. When trying to co witness the bore laser wasn’t visible. It appears in your photos that your rear sight is considerably taller than mine.
Measuring the height of the bottom of the notch in my rear sight it appears to be at almost the same height as the notch on the Holosun.

Did you mean to say, “the installed Ameriglo Lower 1/3 Co-Witness Sight?”

I did. Post edited to correct my error.
