Possible winter project: I have a .22 GPR which functions sluggishly. I suspect at least one broken/missing spring. Is anyone aware of a diagram, drawing, illustration, whatever of the mechanism? Obviously I need to pull the barrel, but beyond that it will be a mystery. If it is just spring(s) hopefully I can find something at Ace - if not, there's McMaster-Carr. Any helpful comments would be appreciated. Thanks!
If I get it working right, I may try shooting it.

Re: .22 Krag GPR overhaul
Dick: You remove the GP barrel and then drive out the 'cross-pin', which retains the extractor plate mechanism.
The extractor-plate assembly can then be pulled out of the two deep barrel-breech holes.
The twin bushings, rods and springs are hopefully intact and come along with the plate.
There are two small bushings that are notched for the cross-pin. The 'rods', which are long screws with smooth shanks,
are encircled by the springs. The rods pass through the bushings and screw into the back of the extractor-plate.
The bushings and cross-pin hold it all in place.
Maybe, even before removing the cross-pin ....
Some deep penetrant, like 'Kroil', squirted down the holes and allowed to 'work', will help the cause.
Working & wiggling parts, along with some 'Scottish' taps with a plastic mallet, on the sides of the barrel (near the breech)
and 'lightly' on the plate, may exorcise the Demons and convince the mechanism, that it just better cooperate!
Some graphics, to help:

Re: .22 Krag GPR overhaul
Thanks a lot, Chuck - that's exactly what I wanted . . .
Re: .22 Krag GPR overhaul
While you have the barrel off the rifle, please slug the bore and measure groove diameter, # of grooves, and twist. This is the easiest time to do all that. Also, you might find someone with a bore scope to really inspect the thing. If you do all that, or any part, I'd like to know about it.

Re: .22 Krag GPR overhaul
You live in No. CA, right? Maybe we could get together on this?
Re: .22 Krag GPR overhaul
I live in Fortuna (south of Eureka, in the Redwoods) and have access via key to a good rifle range. I'm caregiver for my wife and don't travel much. Being old, don't drive at night, etc. If you would travel north, we can get together.Dick Hosmer wrote: ↑Sat Dec 09, 2023 3:11 am You live in No. CA, right? Maybe we could get together on this?

Re: .22 Krag GPR overhaul
I'm in Colusa, and also a caregiver, but such a trip would not be impossible. We stay in Fort Bragg occasionally, but I'm not sure Highway 1 is the quickest route. Let's consider something for the Spring . . . I could do the disassembly here and then let you check it out. Maybe we could even shoot some .30-40 . . . Just looked at Google Earth. You are closer than I thought. What kind of a road is CA36? I've never had occasion to use it.

Hey guys ... Plan a Krag Event!
Re: .22 Krag GPR overhaul
Hmmmm fortuna is only 14.5hrs.... less on my goldwing with a full face helmet (no face, no case!) 
Re: .22 Krag GPR overhaul
CA 36 used to be only for the adventurous. I have not been that way in several years. My oldest son says it's better now, but he was once an ice road trucker. The real problem is a lack of anything like a gas station or even a decent grocery store between Red Bluff and Hydesville. Cell phone coverage is iffy or non-existent in spots. The continual marijuana wars make stopping in some spots, and especially asking a local for help, a risky undertaking. Some of those people are a few cards short of a full deck. Not the best choice for the elderly.Dick Hosmer wrote: ↑Sat Dec 09, 2023 8:56 pm I'm in Colusa, and also a caregiver, but such a trip would not be impossible.

A better road across the Coast Range is CA 20, from Colusa to Williams to US 101 just north of Ukiah. Much more traveled and traveler-friendly. Then 101 north to Fortuna. If you need to stop, there are plenty of safe places & better cell phone coverage. We can arrange to shoot Krags, but the range is close to the coast, wind is sometimes a problem. Spring would be better than winter.
