African Carbines

Put everything together. looks real nice. I was hoping the slop in the action would go away with everything cleaned and tightened up, but no luck. With the band tightened up, the action easily slides forward 1-2 mm - the force of the bolt closing is enough to push the receiver off the plate by 1mm, and pulling the trigger shifts it back.
So, the wood in the barrel bed is tired, and the band is not capturing the barrel into the wood. Nothing a business-card shim can't fix for now. I'll tune it up so it at least doesn't rattle and shift in my hands when I pull the trigger, then I'll be shooting it. Suppose I could sell the stock for a pretty penny and put new wood on it, and fund a few more projects, but let's not get ahead of ourselves.

I was hoping the slop in the action would go away with everything cleaned and tightened up, but no luck.

My older brother who has owned and worked on guns for at least 50 years, bought his first (and only) M1 Carbine from the CMP about 15 years ago. He lives in CA and called me asking why the action was so loose in the stock. I was trying to tell him how to tighten up the trigger housing fit with the receiver, but he said, "No, it's the whole damn thing". His is an Inland and I asked him to check the fit of the receiver to the recoil plate. I ended up mailing him an SG marked Type 3 recoil plate and it solved his problem. He sent me the one that came in it, which is an Inland DI Type 2. With your action out of the stock, see how the recoil plate fits up to the tang of the receiver. It shouldn't go on without at least a slight bit of drag. You might be able to adjust the fit of the one you have and make it work. I broke one of mine, so you need to be pretty careful. I think user Matt_X posted about his method either here, or on the Carbine Club website recently. If your plate is a Type 2, I'd recommend getting a Type 3, though. - Bob

the action easily slides forward 1-2 mm

So, why not epoxy a sliver of shim stock to the front side of the receiver hook and it should eliminate the movement? No damage, can be reversed and should tighten it up. If 1mm isn't enough, use 2mm...so on.
