1.54 vs 1.93 optic height for Razor 1-6

[unclebud]

So what you're saying is that the height is at best, subjective and not based on the best height because that too is just an opinion and not something universal.


Been shooting the AR since 1990, first issued rifle was the M-16A1. I just may know a thing or two about shooting from both the prone and standing/kneeling/sitting and know what's best for me in regards to marksmanship. I was there for the ride when the transition was done between carry handle irons to today's modern CQO and RCO uses of marksmanship. Trained to use both as time went on and deployments came and went into two theaters of GWOT.

So which height mount suits your type of shooting best ?

I just wish they ( Geissele ) made an 1.93" extended. From what I have read, the Razor 1-6 needs a lot of eye relief.

You've read correctly. FWIW, I've used my II-E Razor in both mounts and I prefer the 1.54 mount. I'm 6'0'' FWIW. I think if I was 6'5'' or taller I'd probably lean 1.93. The only time I preferred the 1.93 is with armor.

Just ordered a Razor Gen 2 1-6 and looking at mounts. This will be mounted on a BCM 11.5" pistol with SBA3 brace and a BCM 16" Recce. I am trying to decide on which height and brand of mount. I like the looks of Geissele and Scalarworks. This will just be for range use and home defense. I like the looks of the 1.93" but hate to spend so much $$ and then find out it is not for me. Are there any suggestions that would steer me toward a particular height ? thanks

Trying to use the same mount/scope on 2 different rifles never works if they don't both have the same stock. I cannot imagine you having a pistol brace on the 16" BCM Recce anymore than I can imagine you putting a LPV scope on the pistol. Your anatomy and shooting style dictate scope height. What are the odds of what I like working for you? Would you think I was crazy if I ask for a shoe size recommendation? That's pretty much what you did.

Maybe it's due to decades of using irons and magnified optics on traditional stocked rifles before buying an AR, but 1.5" mounts feel absolutely correct to me.

I've got a few lower 1/3 mounts for RDS, and due to the lack of perfectly situated eye position, they work well and I don't feel like my cheek is gonna fall off the stock. In my opinion, I'm not going to get the same super quick and consistent cheekweld with a 1.93" high mount that I'm able to achieve with a 1.5". I sure not going to spend any money myself to find out.

Naturally, your face shape and shooting history is likely completely different from mine, and you may end up in the opposite situation. We can't say for certain what will and will not work for you.

Absolute at 1.5. But that is just for myself in personal use. I don't know what works best for others because height and length of pull is different with us all.


Look, my honest take here but if you're looking for a solid answer here before you commit is this: Buy all the heights. Yes I know, it's an expensive option but you can always sell or trade later the disregards. Take a carbine course that has you going up and down, a lot of stress and body fatigue. Or do it on your own after cloning a good drill to do from a vetted instructor on the Tubes. You're not going to really know what is best for you, what works and what doesn't, until you actually start using your rifle. It took me years to find out that my resistance to the VFG was wrong. I had always thought of it as a VFG and not a hand stop when moving at pace. Ingenius using it that way, now everything feels natural and hits are a lot more quicker.

Do you have the 1.54 extended or regular length ?

A 1.93" height mount will place a 30mm tube at the same height as an EOTech EXPS.

Your cheek will firmly be in contact with the stock. I am not a big person and the difference between the two heights is so negligible in reality, it's a non issue. You will not be craning your neck like a giraffe to shoot in the prone, and you won't have some pseudo chin weld with the stock when standing.

The 1.93 height wasn't developed for any other reason other than a now deceased CAG Operator working furiously with LaRue to clear the FOV of a 1-4x Short Dot over a PEQ on the top rail. It wasn't to use with a gas mask. It wasn't to give a more heads up shooting position. It wasn't to help shoot with NODs. Any of the previous are coincidental by products.

The difference is less than 0.4". Get a ruler and make two tick marks on a dry erase board 0.4" apart and ask yourself if that's truly the difference between floating in space or still maintaining a cheek weld. And if you have ever shot an EOTech EXPS: you have shot an optic equivalent in height to a 1.93" mount.

Here's a photo essay:





If you lack the ability to grab a rifle and get a sight picture, and the difference in 0.4" of optic height is what ****ed you up, then I don't know what to say.

[GTF425]

How can they not tell? The difference in a cheek weld barely touching the stock and feeling welded to it is very noticeable between the height differences. Too low, and prone is just unbearable. Too high, I feel like my head is barely on the stock and it actually effects my accuracy negatively at distance.

Please reference my photos above.

A 1.93” height mount does not elevate the optic anywhere near as much as people make it out to.

You do not have any understanding of both the length of pull and height. Or you simply do not shoot enough. Both?


Your narrative doesn't fit what's actually going on in real life when the actual feedback of your song versus what's really happening comes into play. Use your rifle, adjust it to YOU and not what you think we should all use.

I have been running a 1.930” height mount way before they became more popular. IMHO, unless you actually try one, you are pretty much guessing or relying on other people’s opinions on what mount height works best for you.
