Working on a long range K-31 Swiss

[sdh1911]

I have a k31 that bubba re-worked the stock for me. My buddy at work wants me to turn it into an F-class rig for him. In return I get a Tikka tac rig, hum, he's got to buy the parts. I'll post it when complete. My personal K31, shoots 1.5" @ 100 yards doing my part. I think hand loads could bring that down a bit-SDH

I've changed my opinion on the muzzle brake over the last two years.
It is a definite help to get recoil sensitive shooters to shoot the K31 often and do it very well to boot. Really helps prevent flinching.
Brings recoil level down to about 6.5x55 level or less.

The Muzzle break for me is more important to took the gases away from the bullets back. It gives a bit of more accuracy. But it isnt so with every barrel, some barrels dont like it and gives you a bader grouping after the use of an Muzzle break. Its a bit of an lottery.

The steel shim under the receiver bolt comes in different thicknesses. You change this shim to control barrel tension. You should address the barrel fit at the end of the fore-end, the barrel needs to be able to move and return to the same location after every round fired. You can experiment with the torque on the rear trigger guard screw. With a good bore the K-31 is an amazingly accurate rifle with GP11 ammo.

There are plenty of K31's with muzzle brakes at the local Military Silhouette shoot in Sacramento CA. Mine does not have one and it is not much fun shooting next to the people that use them. After 10 shots if you don't have a flinch you will. I try to get my firing point as far back as I can and not present a danger to others. I also wear plugs and muffs. I much prefer to be next to the M91/30 Mosins as the long barrel and no brake is not as noticeable.

I'm going to look at a K-31 this afternoon. It's super cheap because it has a threaded muzzle, 14X1 I believe. What brake are you using? If I get this rifle I well be looking at the Swiss products brake. Are their others?

I didn't think I was recoil sensitive until I started shooting the Swiss K-31.

M14x1.0mm is the correct thread and pitch used by the Swiss Products thread on brake and also their dampner.

I've been trying out the clamp-on muzzle brakes. I do have one K31 reserved for use of the threaded brake and also the dampner, if I ever get the time.

I bought that K, $175, could not say no at that price. The threads for the brake are galled but well clean up fine. It's a 43 with a nice walnut stock, nice sling, muzzle cap and 30rds of GP11. I'm doing the happy dance.

It's almost finished, scope, brake are mounted, working on the recoil pad adapter from SP.
