NEA with co-witness Red Dot.

Do you guys have the T1 mounted directly or are you using a mount such as a LT661?

Does anybody have any input on whether or not the T1 still maintains a co-witness with a LT661? I believe the LT661 should add about 1/2-3/4cm of height to the T1.

If you look at the pics posted in this thread you can see the T1 mounted directly.

I can't see a co-witness being possible if you raise it that much.

I'm going to try it with an ARMS #31 mount, we'll see...

Thanks for the insight.

I look forward to reading the results.

Has anyone tried co-witnessing the T1 with the Rauch peep sight? It seems to be somewhat higher than the regular leaf sight.

First, let me say that I'm an ignoramus when it comes to optics! Hehe.

I'm playing around with a similar setup at home right now. I have a Vortex SPARC (T-1 clone type) that I'm experimenting with and even with the lowest mount I don't feel I'm getting a proper co-witness. Still feels/looks too high. Also, it seems odd to look through the peep into the optic? This would be counter-productive, right? I have the Rauch peep set to 1. Upon more messing around, I'm finding I actually prefer not co-witnessing stock irons at all and only having my red dot on target in view. Nice and clean. I have the full shroud on my front sight and looking through the optic and seeing this inner ring looked pretty busy. Anybody else feel the same? Of course, that means my irons will then be useless if I go this route cuz the mount would be significantly higher. Shame, because I really like the Rauch peep and NEA FO front sight combo.

Does this mean I"m leaning towards NEA barrel clamp and stock adapter with BUIS? Damn, more money...

Just to add, I'm also running Rauch's stock adapter which is set to the second lowest height to comfortably use the irons with my CTR stock.

Not sure if I'm actually asking any questions here or stating the obvious, haha. Feedback still appreciated. As for the Vortex SPARC, I'm surprisingly quite impressed with the overall build quality and package...even comes with a neato 2x screw-in magnifier.

Sorry for the crappy phone pics but wifey took the camera!

Just got a Sparc the other day...put it on the NEA rail, but haven't had a chance to shoot it.

I also have the fully shrouded front sight, and the dot is right on the top of it, when I have the rear sight set to 400 M (lower 1/3 co-witness?)

I'll try to take some pic's on the weekend to better explain things. I'm new to all this red-dot/ co-witness stuff :redface:
 
or if you wanna cheap out like I did, pick up a walter red dot, 1200 rounds so far and it's holding zero. The dot looks much larger in the pic than it actualy is.

gota love that nea fiber optic stuff, front post was installed a week after I took that pic :D
 
I too have the Bushnell TRS-25 on my NEA and it cowitnesses perfectly. I am using the factor folder too. Excellent setup. Been using that sight for months and still on the first battery. Dot is 3moa too. Good rig.

Nice! What stock configuration are you using? Factory fixed or folder or other?

So once you know your red dot is co-witnessed, when you take your next shots are you still lining up the red dot with your rear site? Do you need to even bother with the rear sight anymore? I'm new to optics as stated and so maybe I'm confusing myself further...
 
Through some magical science thing, once your red dot is zeroed where ever the dot is is where your shot is going to go. It doesn't matter where in the tube the dot is. I have found the best way for me to use this set up is as follows:

1) look at target with both eyes open
2) shoulder rifle and get proper cheek weld, keep both eyes open and looking at target
3) at this point it should look like there is a red dot kind of floating over your
target, put dot where you want to hit
4) shoot

This becomes super fast once you get accustomed to it.

Disclaimer: I can't remember where I stole this from, I didn't dream it up and YMMV

So then I'd be raising my head slightly and looking over my rear peep sight at the red dot as opposed to through it...am I understanding correctly?

actually, to use your optic you should look (both eyes open, if you can) at the target only and manipulate your gun until the dot or reticle is on your target, then squeeeeeze!:ar15:


generally, the idea of achieving co-witness, is to have the ability to use your iron sights in case there is a problem with your optic.
 
only if your dot is parallax free, for many, one must center the dot in the tube before firing

So then without adjusting the vertical position of my stock, my cheek weld would then be different for aiming red dot or using irons right? That's where I'm getting confused. If I were to use the same cheek weld with irons for red dot then the peep would be in the way. Does that make sense?

You're making too much out of this. Use whatever cheekweld/chinweld allows you to see whichever sights you want to use.

You do not need to line up the irons and the dot at the same time. In fact, that would defeat the whole point of having the RDS.

My TRS-25 is co-witnessed on my 858. Generally my head will be higher when just using the dot. If you go back to the regular rear sight, it won't block as much of your view as the rear peep does.
