I recently purchased one of the carry handles made available by Nordic Marksmen.
Yes it was expensive....my choice...

Anyways,
I took it out today to zero and was getting groups 7-8 inches lower at 50 Yards than what I expected. It managed to zero with lots, and I mean lots of adjustment downwards of the fsp.
I was so unsettled by this that I went home to get a mil spec a2 carry handle. Low and behold it shot 7-8 inches higher compared to my new zero.

It zeroed fine but I did not expect this difference. I eyeballed the heights of this and the cc troy sight and there is a large height difference.

I was wondering if anyone else noticed this? What rifle was this carry handle initially meant to go on? This was on a CC SA20, m4 marked upper receiver.


I am happy but I just wanted to get some thoughts on the matter.

thanks!
 
Yes,

exactly.

I know there is a .04 difference between mil spec and commercial carry handles. I have not broke out the calipers just yet but I think there must be an even bigger difference than that.
Well not a diemaco, but a CC cage code marked handle.

I think what may be happening here is that these DIS were designed to work with the earlier, higher receiver height. Anyone else chime in on how they're using theirs? My front sight post is sunken deep in the front sight base. As low as I've ever seen one, didn't think it could go that low.
 
Damn.... I'd put that under the relic or collectable file and move on lol.
You would probably have to duplicate whatever the CF 5.56 load is as well to make it function as intended.
 
I'm pretty confident it was meant for the earlier, higher receiver heights. I'm just happy I can make it work. It really is a great iron sight. Simple and skeletonized..... and Canadian.
Perfect fit for the sa20.. well sorta...

This.

C7 and C8 flat top uppers have rails that pre-date the MIL-STD 1913 specifications (we got them in 1991) and actually sit higher than other AR-15 top rails. This is why the CF has bought and issues a specific A.R.M.S. 40L sight made for our rails.

What you bought is probably a carrying handle that would normally fit those rails. You should compare the sight height with a standard carrying handle and post the results.

Iirc the c7 and 8 use weaver rails not picatinny. It would work on a true c7. If your sa20 had no marking on the upper then it might work correctly.

hmmmmm , would using this carry handle damage my rails?



after searching.... not likely, IMO

I wonder if some sort of riser would help. I think the lowest full length I have found was 1/2 inch. That may be overkill. I'll prob just live with the sights like this. It zero's and the sight picture is fine.
 
1913 height is 1.835"-1.845". Canadian rail height is 1.842"-1.856". CF rail is higher and that is what the DIS was designed for.
 
This^

And the CF C7/C8 is weaver and not 1913 despite the earlier post. Don't believe me? Try and fit a 1913 accessory on a CF rifle. Most will not fit without modification because the 1913 slot is wider than weaver so the bars won't mesh.

ETA: Canada's adoption of a flat top rail predates the US adoption of the 1913 Picatinny rail spec by several years. Now CC has made uppers to either spec for different markets. I suspect that every LE rifle is 1913 spec.

I don't know what our rails are called specifically but I think that the person who designed them was Mr. Weaver himself as well.
