(Please Remove) Red dot to co-witness on a CQB

[lsgh70]

Is there anything on the market that will co-witness with the CQB. I've got B&T rails and would like to know what to purchase without having to go through the rigamaroo of it all.
Thanks,
Willy

An Aimpoint T-1 Micro will.

the T-1 would or a doctor style or the trijicon RMR red dot, if you don't mind the size.

Cqb co witness

The Aimpoint T-1 and H-1 series will co witness perfectly as long as you use the emergency /close quarters battle folding front sight in the up position, it will put your dot directly on top of the sight so that your rear open short range sight apeture and emergency sight are all on the same plane as the dot. The Doctor Optic even though it appears smaller than the Aimpoints actually leaves your dot in the upper half of your sight picture, I found it to high as I like mine balanced on top of the sight.

ANY form of T1 sight cw depends heavily on the mount used. If you are placing it in a Larue low mount you will obtain nothing. No cw sight picture. Nada.

Fortunately, you CAN run the Larue mount AND still have cw capability by purchasing a low profile rail from gunfactory.ch.

This arrangement will provide co witness through the full range of the CQB drum.

It's Here:

And its pretty. VERY cool. I suspect if a vendor carried these here in Canada they would not take long to sell out.

My package from Switzerland arrived at the CO-OP postal outlet this morning.

In a surprise maneuver, the Canada Pogues subcontractor failed to deliver to my doorstep and instead deigned
to venture no further that the community box to drop off a delivery failure card.

I wasted not time opening it to take photos and take measurements.


Overview:

I laid out the new G-Force #30831 rail on the table beside the much more common B&T rail. This should give an immediate visual context for actual size.

Dimensions:
Height of B&T:

0.547" converts out to 13.89 mm

Height of G-Force:

0.395" converts out to 10.033 mm


Scurvey. It is obviously lower and our measurements now tell us that the actual difference regardless of what the comics say is about 4mm. But as interesting as this is, it does NOT convey to you is that this rail is quite a bit heavier despite its smaller dimensions.

Maybe double the weight. This product is definitely made out of some decent quality steel.

Weight:

I put the B&T on my trusty RCBS electronic scale. After a quick check for zero, I was rewarded with an accurate reading of 82.14 g

Next went the G-Force. Right over the top actually...

Ok. Well, we know it is small and that it is heavier. Now the big questions:

• So what?
• Who Cares?
• What is this going to do for me?

So what?:
As a lower profile rail, this product is unique for the fact that it will allow full cowitness with an Aimpoint Micro T1 sight.

This is also different from what the B&T Fore-end Quad rails promise, as they are prone to wandering zeros due to weak mechanical design resulting in a loose fit. These rails lock up tight for repeatable zero shot to shot.

Who cares?:
Anyone who uses a Swiss Arms rifle in diopter sight configuration, does not have access to a flat top receiver and requires the combination of reliable zero and cowitness will benefit from purchasing this product.

What will this do for me?:
Sometimes, the pictures really ARE worth a thousand words. So without further ado...

The money shot...

That's usable cowitness even in the CQB reticle on the diopter right there boys and girls.



You will also note from my photos that my particular T1 is mounted in the higher profile Larue QRM instead of the lower (and much s**ttier) Aimpoint factory mount.

Hope you enjoyed the pics. I'll be enjoying at the range this weekend in some +5 weather (God willing).
