So I have a Cooey model 39 single shot that has basically new factory barrel on it, probably less than 1000 rounds through it. It was in a damaged wood stock that I fixed up enough to shoot it ok. ( it's repaired with epoxy and cleaned up, but needs to be bedded still ) It ruined the wood look however, so I painted it up camo and the kids love it. It shoots very very well. I'm trying to decide if I should try and mount an optic on it and see if the trigger can be worked, its awfully stiff but breaks decent. I took it out shooting the other day, 50 meters with the iron sights and it shot a 2", six round group. the front sight was completely blocking the black Biathlon target. I think its capable of much more.
Has anyone mounted an optic on one? Is the factory trigger workable? What kind of groups should it be capable of? If it can't be great then i would save the money for something else.
 
This is a guess only, but they way I look at it...think about what/who this gun was really built for, what it cost originally, etc. I think it's highly unlikely that you'd be "wowed"by the accuracy but on the other hand, it depends on what your expectations are. Some people buy a $1,000+ Anschutz rifle then don't bother to do any ammo testing or put even a 1/2 decent scope on it. What you get out of it will be heavily influenced by what you put into it. Lots of factors impacting accuracy.

Sounds like pursuing the accuracy potential of the rifle might be a fun project, and provided you don't have to spend too much-the risk level is very low. I hope you DO mount an optic and do some load testing-I'd be curious about what you find out! The 39s are nice, light, compact simple guns. I like the original/older Cooey-built ones.
 
I believe most old Cooey use a Weaver #2 side bracket.

And have the receiver taped according.

Not much you can do with the trigger except polish all touching surfaces and maybe use a high moly paste on them.

Hope that helps
 
Whats the best method in tapping them? I've got a Cooey 75 I've been thinking about scoping up, but I'm terrified that i'd end up botching the process.
 
Think a good rifle stand that you could clamp the receiver in.
A laser that would fit into the scope rings.
Line things up at say 20-30 meters and mark the bracket holes.

Sorta like this.

Or take it to a Gun Smith.

Wow I have never seen that kind of a mount before. Interesting. It that just for clearance for the ejection port?
 
I posted this in the Cooey Mods sticky - its the second last post (currently). Despite comments made there, I found teaching both my kids to shoot that a red dot is the way to go, no need to focus on two sights and a target, and no wobble magnified like what happens with a scope. If you decide to go the way I did with my friends rifle for his son, let me know as I have another Weaver sight base that I used in the following information and you can have for free. I would look at picking up a used Bushnell TRS25 - small light and will do the job very well for you. Lots of other scope / mount suggestions in that sticky.

Something that may help folks out in a similar situation.

A friend wanted a single shot 22 for his son for Christmas. I managed to find him a Cooey 39 in nice shape from a buddy at the gun club who had redone the stock when he got it for his kids years ago. Bluing is a bit thin but not bad.

My friend wanted a red dot on it for his son to learn how to shoot, As you know the receiver area is pretty small to do that with (although lots of pics of others that have done so). I mocked up something else and with his ok went through with it. The rear sight is attached by a screw into a drilled and tapped filler plate in the dovetail. The screw has to bottom out on the dovetail to hold it in place.

I determined that a 10-32 screw would fit the filler plate hole. I picked up a package from CTC and then using a file and drill, reshaped the head to fit a Weaver 76 single hole base mount and cut to proper length with a dremel cut off. It has a 8-40 screw so I had to ream the hole out with a #11 drill bit. A dab of cold blue on the screw (although it doesnt look like it in the picture).

The base sits slightly above the barrel, so I roughed up the bottom of the base slightly, and put some JB weld on it and then screwed it into the filler plate so that it would bond to the barrel. Lined up the base and the barrel and let it set up. I wanted to make sure that for a young person he wouldnt knock the base loose. Waited 24 hours, all solid, removed the screw and put some blue lock tight on it and snugged it up..

Put a TruGlo red dot on it (a TRS25 would be sleeker) and its ready to go. Leaves the bolt area open so can see if cocked or not.

Great info on scope mount , any idea if that mount would work on a Winchester 67 single shot ?

Cooey single shots are actually spectacularly accurate, I regularly shot cream of mushroom soup cans at 100 yards with the open sighted Cooey 82 of my grandpas. They have long heavy barrels for a 22, very nice to shoot and very Canadian.

Interesting Chas, thanks for posting. I have a TRS 25 already. I was hoping for a much newer, larger diameter scope to be mounted ideally. I know the red dot on the TRS 25 is not super precise. ( both my boys, 8 and almost 12, shoot well with the scope already on my 10/22. ) The oldest shoots my 6.5 Creed up to 300 meters all ready.

@ HuskyDude, or anybody, do the Weaver side mounts come in a taller option?

The newer aluminum side mount (see Husky dude's post) should work with up to a 40mm objective. There are two different ring sets available, short and long, but they are the same height. The short version is the one you want for a Cooey.
