I shot my 1095ST for the second time yesterday and something came up. As a side, I had added a Bushnell red-dot and my target was 25 yards out.
I had great difficulty picking up my rear-sight. I could see the red dot from all angles but I became uncertain if I saw it through my rear sight.
As a result my shots were low and right primarily.
Has anyone else had this problem and if so, what was your solution?

It's called "co-witness"(ing) to be able to have red dot and iron sights lineup. It's difficult with the HP due to having such a low rear sight. You can do it with using see-thru scope mounts, but that would raise up the scope many times too high, to get a good cheek weld.

Or, as another resort by doing what is known as 1/3 sighting if you have a red dot scope that is at least a 30mm or larger objective. If scope is a mini/micro RD scope then co-witness won't work. This is where you use only the red dot as an upper sighting system and still seeing the front sight under the scope's illuminated dot while looking through the scope(red dot) and align the rear sight up with front. You have both sights capability at same time. This is where having the correct height scope mount comes in where you adjust scope up/down with using rail height adapters sometimes. Of course, getting the scope too tall is just as bad as using see-thru mounts due to not getting good cheek weld with neck stretching and not having firm stock to shoulder placement for recoil and throwing shots off.

I hope I explained well. In other words, with using a RD, you'll have capability of using just the illuminated scope dot, and also using the rear iron sight and aligning/seeing the front sight also un the lower 1/3rd of scope under the illuminated dot.

Disregard the measurements...this is how the two types of alignment look.

In some cases, the 1/3 third co-witness will actually align the red dot with the sights, since the dot "should" be lined up on target no matter where you put your eye, up to a certain limit.

Fantastic pictures!! Thx!

Now, my biggest problem is seeing the back sight. That sight is so small and it doesn't jump out when I bring the gun up to my eye.

I wish I could see it as good as this picture!

Thx again!!

You have to get your eye up close to a peep or aperture sight, it is NOT a ghost ring sight.

We were taught to put our noses against the charging handle on the M16, that's why many of us older guys dislike the longer A2 stocks. They work for a scope or red dot, but they aren't very good for an aperture sight.

Thank you so much! Point taken!!

I used this BSA red dot scope. I believe it is 30mm. I bought it off Amazon and it was very reasonably priced. It has perfect co witness with no riser. It's very easy to use the iron sites when the red dot is not turned on. I did have to cut about a 1/2 inch off of the front of rear site to get it to fit but that was easy. I removed the rear site and used a dremel tool, only took a few minutes.

It's also the same 30mm BSA RDS that used to come in the factory carbine package, and that HP used to sell on their .net accessories page. I got one when I bought my alphabet soup 4095 8 years ago.
