Izzy 46 carbine...... maybe...

[dan_house]

Somewhere at home I have a pic of a Izh 46 "converted" into a carbine

wire stock bolted to the bottom of the target grips, scope added on tallish mounts and a muzzle device to make the gun even quieter.....

Ive had the idea to do some thing similar.... calipers, fusion360 and a 3d printer would make short work of the stock(and preserve the factory target grips). but at this planning stage my hang up is getting enough clearance under the scope to let the loading gate swing open to load it. which it appears will lift the scope up seemingly pretty high   

Also like to NOT make any permanent mods to the gun (and have considered getting AV46 just for this "conversion") as the Izzys have been part of the Russian embargo for a while now.

I realize a 13xx platform could be built to do the same basic function, and I have "carbinized" a couple of P-17s. the Izzy though has some magic to it, and the single stroke to charge it is way easy to do. Add in the inherent accuracy of the platform and it seems a no-brainer....

SO who has done this?

There is guy that shoots with us in Bay Point (Concord, CA) and he converted an IZZY to a carbine.
Wood stock and all.
I think he took a barrel from IZH60 but any barrel would do.
Maybe a LW barrel from Crosman.

Id just take the front sight off and add the device. no barrel swap. Although a Rev2 (with an AV46...) might need the longer barrel

after scouring the internet for scope mounting options that weren't skyscraper height, I ran across long eye relief and pistol scopes. Thinking those would let me mount the scope far enough forward to eliminate the loading port clearance issue

You guys might be looking for these images:






The idea of adding a stock with a less constraining pistol grip to my M46 comes to mind every so often.  The grip on the P17 is more comfortable to fit with a butt stock type hold, for example.  I have thought of scanning the P17 and importing the grip shape for future use.  I don't have a scanner, or it would have happened already.  Or, one could fashion a more conventional rifle style pistol grip.

As for barrel changes, I think the stock barrel should remain because that is where the already known accuracy comes form.  The idea that you would boost velocity is somewhat misguided.  There simply is not a lot more air to expand in that single stroke system, for a longer barrel to extract. 

For more power, first set the compression to the max via the factory adjustment screw:
https://www.gatewaytoairguns.org/GTA/index.php?topic=153027.msg155687779#msg155687779. 

Then fill in the piston face groove with soft rubber to boost compression further, yet allow the lip seal to function.  One user placed a rubber band in the piston face groove with apparently good effect.  I am concerned that it would drop out, but this user added a little glue:  https://www.gatewaytoairguns.org/GTA/index.php?topic=153388.msg156094214#msg156094214

I have done the compression adjustment, but not filled in the lost volume in the  piston face.  Either way, the boost in performance comes at the expense of more charging force.  Not hard, compared to the P17 for example, but one wonders if overdoing this might fatigue or wear the cocking linkage or pivots prematurely.  There is a small change in report too, but mild x 1.25 is still mild. 

Sure, a longer barrel would make the M46 quitter, but it may cause POI drift sensitivity, as thin barrels are fragile, and long barrel stress their mounting system.  Rather add a simple shroud made from a very light weight tube.  It seems that the above images show such a shroud.  Perhaps the full barrel extension is a shroud/LDC over the stock barrel.

As for adding a stock, what would be comfortable and work with your choice of sights would be a rather personal matter.  The images above sure look good.

The guy here in the Bay Area (SFO) says his 46m rifle, while accurate, won’t even make a hole in the target 10 meters away.

Frank,

That sounds like a fraction too much friction in the long barrel...

[Frank in Fairfield]

He shoots 10m with me tomorrow.
I will tell him about your interest and tell him to get on the GTA

[dan_house]

I have that pic, and the one that I described in the OP...

DaveG made the thumbhole in that pic. Great work, but he's stopped making stocks due to some family issues. And yea that pic is kinda what started the 46 carbine thought process

I like the idea of turning the M46 into a more stable shooting platform, without modifying it in any serious way.  At the same time the breech system seems weak to me, with those flimsy foam rubber seals, that take a set if you leave the breech closed. 

Could one make a minimally improvement to the design, that still works with setting the valve?  Or, in the case of a low scope mount, not get in the way?  Perhaps too ambitious and expensive a project, with a high risk of trashing something that works.

[Frank in Fairfield]

The guy that shoots 10M with us didn’t show up last night.
He converted a 46 to carbine.
This one shoots just as well and has the same quality barrel.
It is a springer though:

It’s illegal to put a stock on a Izzy 46 according to the ATF. The company produces a .22LR version. Got all my info from RinkGrip company I tried ordering the walnut thumb hole for my izzy46.

That sounds odd, Mike.  If you can put a stock on a Notos, or a Marauder pistol, why not an Izzy air pistol?

Having a stock that fits a .22 rimfire pistol also should not be illegal, until you attach it.  Consider owning an AR15 pistol and an AR rifle.  You could take the rifle stock off and attach it to the pistol, but you have broken no law in the possibility; only in the act.

If you are concerned about "constructive possession"; you own only an Izzy air pistol, not an Izzy firearm.  So, the fact that the company also makes something that when attached to the stock would be illegal should be moot. 

The AR pistol and rifle ownership example is much more likely, and yet owning both is legal in the US.  Even buying another stock for the rifle is legal.  Even if you own an AR pistol.  What might be a problem is buying an AR stock, if you only own an AR pistol.  If you own a BB gun replica and want to order an AR Stock for it, or for your Notos, I do not see how that is illegal.  Ditto for a wooden stock for the Izzy air pistol.

Now, importing anything that could be attached to a firearm might be something that has blanket rules.  But if the Izzy stock was in the US and sold at Pyramyd Air, there would be no problem.

My suggestion is that you design a stock for your Izzy and 3D print it, then cover it in wood veneer.  I wonder if RinkGrip would make a 3D scan of the stock so you can print one like it.  Else, starting from nothing could make an interesting project.

If you had a scan of the RinkGrip stock, you could cut one out of wood using a 3D router; or 3 or 4 axis CNC mill.

Well, importing any Izhmash products is illegal due to the company being Russian (import ban well before the Ukraine invasion...) and them also making AK's and parts and such. So I dont think thatll be a legal issue....

Looked at it hard again last night..... so no mods that cant be reversed, no mechanical mods or performance changes. Definelty no longer barrel, as it kinda defeats what Im fter for that gun

The Rink stuff is definelty cool, but not my aesthetic leanings.... so got some prints of the 46 off the web, and a sharp pencil....

Mike,

I am about to email you the STL files for a VR game stock that I designed for my brother, in a blinding hurry.  I took images of a Browning Citori and scaled them for a length of pull to 14".

The stock is in segments so that one could more easily find a printer that could do the job.  Had a guy in South Africa print the whole thing for $45, and used the assembled stock while visiting SA in April/May.

I am posting just a few images here. I am sure I can do a more refined job than this design.  But, duplicating the pistol grip on the Izzy stock higher up in this thread, without real measurements would be a huge challenge.

I would even suggest something that looks like a "fitting stock".  Something where the critical fitting dimensions can be adjusted.  Then when you have the composite stock set to your likening, a one-piece (or two-piece) version is designed.   The pistol grip of the fitting stock could be covered in clay to mold it to your hand; or it could have add on bits of varying thickness/shape.

I have toyed with the idea of taking a P17 pistol grip and adding material to form a carbine stock; adapted to fit the Izzy grip frame.  Making that into a thumbhole style by could certainly be done.  I might be able to get a 3D scan of a P17 grip, as a starting point.  Else, taking measurements off a P17 by hand with a caliper might have to suffice.  I suggest the P17 grip because it seems to be a minimalist grip that fits many hands well.

Dan, the Izzy may be banned from importation due to being Russian, but the RinkGrip stock would be German made and imported from Europe.

The Air Venturi 46M is still for sale at PA:  https://www.pyramydair.com/product/air-venturi-av-46m-match-air-pistol?m=5257

From the image below, the gun marking clearly states that it is made in Russia.  Perhaps the Izzy version is banned because the same factory makes AKs?  Or, PA have an unsold stock of these air pistols left.

[dan_house]

yea the Izzy versions are made int he same factory as AK's

Did not know the AV versions were Russian..... so ya could be they just ahd some "leftover"

Dan,

I took the liberty of emailing you the STL files for the stock segments above, to your drsub address.  I don't expect you can use that directly, but it might inspire some ideas for a custom stock for the Izzy 46M.

[dan_house]

Sweet!
Tahnk you!

[dan_house]

found the other pic. has a kind of steampunk vibe to it. also seems fairly fragile…..
gotta wonder how long the barrel securement will withstand the weight of the scope setup

[Motorhead]

That is really cool. vintage long tube 3/4" optic, yea very old school "James Bond" appeal to it.
Looks to be an original 46 and not the M variant ?
