Concept/Prototype Rear Mosin Peep -- Thoughts?

[Josh Smith]

Intentionally placed here as this is not a sale.

Hi All,

I'm hoping to get your feedback on this design. There will of course be changes prior to production, including a less-pronounced base and a longer cantilever.

As well, the prototype has a 0.094" aperture, but production will be interchangeable.

It's a given that the production will be much more polished, and I see where the mistakes are on the prototype.

What do you think of this concept? It will replace the Rigby-style rear:









I'll need to speed up production prior to releasing this as well.

It is, however, a very sturdy platform and brings the aperture much closer to the eye than Arisaka-style sights.

Thoughts?

Thank you,

Josh

Interesting. Will it be marked and adjustable for elevation?

Also, IBPNMACASMM (In Before Pro NRA Makes A Crack About Sub MOA Mosins).

My only thought would be if the heat from the barrel overtime warps the sights elevation.

definitely looks like something worth perfecting for the "i just want a shooter" crowd. like Gunman said, possibly a set screw in the sight tang to make small elevation adjustments? interchangeable apertures? Just a couple ideas. looks good though josh! and if it's coming from you, we know it'll be made "mosin tough"

Very Nice Josh. Looks similar to the Peeps Sight system people put on their SKS by replacing the Leaf Sight and pinning it on it on. Maybe put something of a reinforcement bar or bridge by the concave part of the ring (the little valley between the ring and sights) and you might have something.

Maybe, the Soviet Mooosin can actually hit something heheh. But you need to come by and visit me in TX!

Kind of like these

I put mojo sights on my swede but have yet to shoot it. Hopefully this weekend.

I don't have any Mosins at this time, largely because my aging eyes just can't see the forward mounted rear sights.

While I think that you have developed a clever partial solution, it is still rather a bit too far forward to be an effective target type rear sight. Also it needs to be easily windage adjustable to be truly effective.

IMO, if someone feels that their Mosin-Nagant is inherently accurate enough to warrant peep sights, they should just bite the bullet and drill and tap the rear of the receiver and have a good sight that is adjustable for windage and elevation installed.

I am not trying to criticize your sight, as I said it is a clever and relatively inexpensive device as opposed to the expense of buying and then installing a decent rear sight. I have a Swedish M96 and with the stock military sights I have trouble holding the black on a 100 yard target, with the target diopter sights it is like a whole different rifle.

I think, by the theory of a rear peep sight, you're focusing on the front sight so it shouldn't matter whether the rear sight is farther back or in the position of the open rear sight. The rear aperture will be out of focus either way. The aperture size just needs to be appropriate for the distance from the eye.

Unless you're strictly target shooting, you don't want the outside diameter of the rear sight or its support structure to block out too much of your down-range peripheral vision.

I'll bet some Mosins, like my M39, would be amazingly accurate with a peep rear if an aperture front replacement sight were also developed. (Like close to the M28/76 target rifle.)

Hello,

Thanks folks.

The aperture will indeed be moved closer to the eye for production. Chopping a few inches off was just for ease of photography! The initial idea has it just clearing rounds loaded from stripper clips.

I see some glaring problems that I'm going to correct in the next prototype.

This one is adjustable for windage and elevation. Problem being that those adjustments are done underneath and they're not too refined. I'm working on that.

This is designed to be a pure target sight, yes, but in the works is a shooter's sight, sort of like one found on sub-guns in WWII.

Mojo sights are good for those who can use them. However, they give up a huge advantage by taking the place of the stock sight without moving closer to the eye. Many can shoot stock sights as well as the Mojo.

My Rigby-style sights were good and pretty successful, but they were very labor-intensive to manufacture. I had to deal with stabilizing on X, Y, and Z axis, but I'm discontinuing them, I think. I'm getting the last ones out now.

These should be much better. It's the R&D that's time consuming -- but it's fun besides!

Regards,

Josh

I like it. Please post how the modifications are coming along.

Well, my old rotary tool -- a Dremel adjustable speed, if you believe it -- finally gave up due to the switch.

I had tried one of the new variable Dremel tools. I've never used such a piece of junk! The magic smoke escaped and the Dremel stopped working.

I ordered a Black and Decker that should be here today. From what I've read, they're actually better than the new "Made in China" Dremel tools and have much more torque besides.

They will also run the same accessories and even the flexible extension, which is a must, is supposed to fit. We will see.

Since this one is going to be a three-speed instead of a variable (couldn't find a variable B&D in stock anywhere) I'll likely wire up an outlet with a rheostat. That will give me infinite control.

Since the prototyping isn't necessarily "work" as I define it, I might get more done this weekend. My brother's here on his way to a wedding, but Saturday the wedding in Chicago will be going on... so I might play with it then.

Heck, the sister-in-law (Mrs. Bro; my brother is simply "Bro,") my wife, and my mother are all supposed to go do something today. I might take my five-year-old over, let the dogs babysit him, and do some work on it before going to the shop for the night. We'll see.

Work hours, right now, are from 9am to 2am or 4am -- 6pm to 2am or 4am being spent in the shop. Monster coffee drinks help! If, however, my work starts suffering... well, that's when I stop and get a little sleep.

But I digress. the next one will have better form with it. It will still be rough, but it will look more like the production piece.

The best way to make it adjust for windage would be to drill the actual mount for screws. Most aren't willing to do that, though, so I have to find a work-around that won't interfere with the sight picture.

Is there any reason folks really want the rear sight to be adjustable? The front sights are fully adjustable -- at lease mine are -- and i never saw any reason to have the rear sight adjust. I'll do it if that's what folks want, but I'm curious as to the reason why.

Regards,

Josh

I appreciate what you do Josh.

I am with highpower -- too far forward for me -
Have you considered reviving the old pacific cocking knob peep ?

If you go through dremels often, I suggest getting a Foredom rotary tool. Same deal, has a 3-jaw chuck that'll take any dremel tool and it has a foot pedal. Also the customer service has been pretty good to me.

Hello,

I was selling those for a while. In order to properly stabilize them, I had to go pretty in-depth with the manufacturing to get it balanced out on the X, Y and Z axis. They work! See here:

http://www.calguns.net/calgunforum/showthread.php?t=704643

The last type I made had the peep in front of the stabilization system, but still far back.

I've discontinued them and am getting the last ones out now. They were just taking too much of my time. If you want one, I think I still have all the materials to make one if you're willing to wait a couple, few weeks.

Regards,

Josh
