I’ve been shooting with iron sights for 45 years! I just purchased a Sub 2k and the Mcarbo optic mount and the Mcarbo rear flip down/up peep sight. I also purchased a AT3 Tactical RD-50 Micro Reflex Red Dot Sight. I have not mounted them yet. However, I mocked them both up and it seems the red dot sight is pretty darn low, with the front sight in its view. Do I need to buy a riser, or do I just co-witness the optic with the front sight? Would an optic with a higher rise, like the Romeo 5, be better? Sorry for my ignorance, but this stuff is all new to me I’m old-school!
I watched a bunch of YouTube videos that show the red dot sighted in with the front sight, but my crazy mind is thinking the optic should be used alone, then flip it to the side when I want to use the iron sights. I’m just not sure if the optics need to be raised? I’ve also found front folding sights, even more confusing!
Hopefully you guys can shed some light on this for me!
(The SOCOM upper is mounted on my AR lower in this pic. The scope, etc, is on the .223 upper. Nothing on the SOCOM but the red dot)
See? No front sight. That’s the beauty of a red dot.
This might help you. Instead of removing the bolt, though, you just have to fold the Sub. Easy!
Ignore the irons all together though you want to keep them in case your dot fails. If it does just flip it out of the way and use it the old fashioned way: iros sights.
I recommend sighting on a bench rest.
If you want you can co-witness the red dot to the irons but it’s not necessary
Using the MCARBO flip mount, MCARBO rear folding notch site, and the stock Kel-Tec front sight… my Primary Arms red dot coexists perfectly with both. I don’t even have to turn it on. Just gotta remember to remove the lens caps.
Some folks find it distracting to see the iron sights through the dot. If so get a riser, folding sight or remove it altogether. Really a matter of preference.
I use the Red Lion folding sight. It’s pricey but well made.
You guys are the best! Thanks everyone for your responses.
For now I will keep the Sub 2K front sight with the red dot, I’m just wondering where the red dot should sit, height wise, total height off the pick rail so that the view is correct? The front sight seems in the way, but if co-witnessed I’m assuming it’s supposed to be like that, but I don’t think I like it, I’ll have to test at the rang, I guess.
The other issue is when the Mcarbo mount is flipped to the side and rifle folded, the optic sticks out a lot. I’m concerned it could get damaged in my Tactical backpack/storage case. I was thinking of adding a quick release, (with adjustable height), pick mount between the Mcarbo flip mount and the red dot. Is this a bad idea? It will also raise the red dot, hence it might give me the sight height I might prefer. I would of preferred the design of the Midwest swivel optic mount, but I’ve heard it come loose off the M-Loc rail over time, and I don’t like the idea of turning the bolt handle into a slingshot in front of the optic glass!
Keep’em coming guys/girls, I like all the advice I can get!
High off the bore is comfortable. But it can be considered limiting given 9mm ballistics. E.g. zero at 50yds and elevation is farther off at 100 for a high off bore than a close to bore.
I prefer as close to bore as I can consistently pick up for this reason. Others prefer comfort. If you shoot at a fixed distance - it won’t matter a lick.
The reason AR sightsvare high off the bore relates to the straight buffer tube/receiver extension. The Sub 2000 has the same straight tube, but 9mm is not flat shooting like 556.
Remember to cover the optic in inclement weather. In this case the hole in the chickens ass and the open mouth coexist perfectly with the irons and red dot.
Your choice but a “reliable” quick disconnect is hard to find and expensive and sort of defeats the quick deployment of the flip mount. The latter does project but seems to be remarkably stable despite bumps and abuse.
Oh. I see others have now properly welcomed you to this unique and somewhat demented place.
