Can anyone tell me what they use for aperture sights on the BB? Also, where can order a BB and are they currently in stock?

Most likely, the sights used on the Izhmash CM-2.
BB 7-2 with diopter sights?

peep sight for bb



Sometime ago I sent M.T. Guns this email:
Quote:
I'm looking for a
Biathlon Basic 7-2 with Dioptrical Sighting Device (factory, adjustable peep sight).
Just as pictured in your new advertising flyer - Biathlon 7-2 KO (with peep sights).

What would be the price?
This is the response I received:
Quote:
Sadly, Alejandro, we have no 7-2s with iron sights.
And it would be pretty much of a chore to put iron sights on the 7-2s we have, which all come with a scope rail.
Thanks for your query,
Bruce Duncan

Jahred,
what is your fancy when it comes to shooting? Do you see yourself shooting in some sort of competition at some point? (I think you are missing out if you don't give it a try.) Are you just a plinker, or a sometimes squirrel hunter? Nothing wrong with whatever your fancy is, but it might help you make the decision of which rifle to buy.
I sort of agree with AOM except that my suggestion would be to buy the BB, the CM-2 and build a 10/22, but then there is also this http://www.cooperfirearms.com/rifles.php?rifle_name=jsr

Diopter Sight System on the Biathlon Basic

This problem has been addressed:
BB 7-2 with diopter sights?
the easist way to get peeps onto a BB
However, it bears a second look.

Especially, considering, a rear sight could clamp on-to
the existing receiver groove or weaver rail.

The clamp-on barrel band with front sight base seems very viable.
And, most importantly, no machining or drilling is required.

I too am interested in putting a diopter sight system on the BB.

Has anyone thought of or had any experience with one of these?

It's a barrel band with a sight base. Seems like it would be the easiest way to put a front sight on the BB, if it works.
Champion's Choice: Item #CC812S
Clamp-On Aluminum or Steel Front Sight Bases - .812 or .750 Diameter

BI 7-2 KO with Diopter Sights

There is at least one person who owns a BI 7-2 KO with factory aperature sights.

Following Images Courtesy of sillymike from the thread IZHMASH Biathlon basic at CanadianGunNutz.com

Quote:
Since I've been a good boy in 2005 , Santa said I should me get another rifle ...
So after two years of looking at them, I finally got one of those crank action russian 22lr.

It looks a little odd, having classic "hunter" type of stock with biathlon front/rear peep-sight...
The rear is mounted on a 11mm rail, so I could use my Anschutz sight should I want to.


Quote:
The factory insert were not that great, but thankfully, it is the same size as Anschutz's.
So it now wears Slim line insert.

I should take a picture from the front, IZHMASH has a different way of crowning a barrel!


Quote:
This model even comes with a box full of goodies!


Quote:
I took it out to the range last night...
It shoots pretty good, from the prone position on "sporting" target, I was getting 98-99/100.
My girlfriend even had to show off by borrowing it and doing a perfect 100... Ho well, she might just have to get her own.

What I like;
- accurate
- smooth action
- peep-sight
What I do not like as much...
- The "hunter" type stock... The cheek piece is too low for me.
- The ugly looking mistery plastic magazine. The work 100%, but I still not a big fan of plastic magazines.
Anybody else using these?
I'm thinking that it might just replace my Anschutz 190 in the sporting gun role...

Safe shooting,
Mike

The problem I see with a barrel band is that my barrel is tapered and would need to be turned to make the contour work. For the same or less money you could have the same gunsmith drill and tap the barrel for a sight base. Centra makes a rear sight for flat top AR's which should work on the Weaver rail and a machinist/gunsmith could make an 11 mm dovetail to replace the scope rail and that would allow you to use Item 10005 Centra Visiertechnik GMBH 10005 CENTRA ECONOMY REAR DIOPTER SIGHT which champchoice sells for $186.

Cost Effective Diopter Sights

CM-2 (Biathlon Rifle diopter) Rear sight - USA Retail Source???

On most tapered barrels as the muzzle is approched the taper decreases drastically.
To the point of be almost a straight taper.

As such, the clamps of the barrel band should be able to compensate for a slight taper.
If any taper is present at the muzzle.

An important objective of configuring a BI 7-2 KO with diopter sights,
was to avoid costly machining and expensive gunsmith modifications.

Another objective was to avoid the use of expensive parts.
The addition of the diopter sights must be cost effective.
In-order to be worthwhile.
