Finnbiathlon: any interest in a pictoral and/or teardown?



Log in to see fewer ads
Finally put my hands on another Finnbiathlon. This one looks a little rough and has had numerous owners from what I can tell, but shoots a dream. Bit long toggle length though.

Any interest in me taking tons of photos and putting up somewhere? Rare enough rifle I've had zero luck finding much out about disassembly or maintenance.
Young Fella I bought it from in MI said he'd found a parts diagram online, but my google-fu must be weak. Nothing on the big parts sites I've checked either.
Maybe one of the younger folk will help out here?

first photo of a target from it. I used OLLLLD Aguila Golden Eagle to start a sightin and then when it was moment of X, I started switching up. Wind was from behind (weirdly) that day but slow. so /shrug. it ate up Eley Tennex like born to it. first group with it the loose nut behind the wheel put 3 in the same hole and then pulled 2 in a row with poor trigger management. (has a mile of take-up)
Since then I've learned it LOVES Aguila SV and Golden Eagle, tennex, and RWS R50.


Hmm not linking right...
pic try #3
bah! Loading from local now.

1st target. bit of an odd order we shot in due to the light and some target hanger issues.

Yes. I find the sport interesting even though I'm too old for it, and still find the rifles beautiful.

Couple of pics to get this overview started. Filling up my RFC cache. Have to find a replacement for a cloud photo spot.

It's been re-painted a couple of times from what I see inside the stock. First image is from the polite young man I bought it from. He told me he obtained it from a fellow in MN. He and his girlfriend were sporting a Russian 7-? in a brand new Lost Nation R&D stock, and an Anschutz.

Has a CRAZY spinning/rotating ejector I'll follow up on. Trigger pack is mildly annoying to re-insert, but if you do things in the correct order it is MUCH easier.

The young man mentioned he'd found schematics online. My google-fu is failing me for I cannot find anything for this online other than general photos or for-sale ads in Finland and Belgium.

I've never seen a front sight like this one before. Rifle is by Tampereen Asepaja Oy of Finland, NOT Sako as seems to be implied in some of the VERY few threads I've found about this rifle. So perhaps the TAP on the front is for them somehow?

Rear sight is fairly normal seeming, but unique. Has an Anschutz-compatible screw block inside the rear sight, so my adjustables will fit for the grandkids. hehe. the eye relief cover is a well cut off old 35mm film can.

edit: forgot to note that the hook on the stock is an add-on. Paint is cracked at the joint, and the coverup over the screws is starting to peel.

Couple more shots. Note the curve in the stock.

Bolt removal and teardown:

Hmm seems I need to clean up my photos. Time for a new photo host I guess.

Looking forward to seeing the trigger mechanism and bolt face.

What is the function of the curved stock profile? Seen it before on rifles from that era. Since it rides on the back barrel-up with the stock in the small of the back, what is the advantage?

Popcorn bag at the ready...

The curved stocks of that era seemed to be for keeping the arm to wrist angle consistant without having to angle the hand outward. Was it really helpful? ehhh I dunno. The holes in the stock are for the adjustable tie-up for the sling.
Not sure why someone added the metal cover piece. Tie off the end maybe?

The interior parts of the trigger group have rather sharp corners and edges, and almost have an unfinished feel to them. Save where they have slid against each other since 1978...


A little something to tie you over.
