The Swedish mauser uses a M-96 bayonet . I do not know of any Swedish M-38 bayonet . If you really have the correct bayonet , there may be burrs or grease & grit inside the handle or muzzle ring that will hold the bayonet in place . You could use an extra pair of hands or a gun vice to hold the rifle while you pull on the release button with with one hand & the bayonet with the other . If that releases the bayonet , then you need to clean & deburr the handle & muzzle ring . Sometimes the end of the bayonet was used as a hammer & gets dinged up or distorted . Work on it carefully untill it releases with ease .
