Gfrad.
I have the same problem.
Do you have pictures of the barrel to share?
Thnks

I have no pictures but if you give your gun to gunsmith and tell him of your problem he will shave afew milimiters of the barrel and your problem will be solved,i watched gunsmith do the work it took less than 30 minutes.the problem is with head space ,being that the rims of .22 are not all the same tickness the thicker ones will cause your gun to slam bam.i found that with magtech high velocoty ammo and i believe with any russian ammo you can find the gun will shoot fine,if you decide to use other ammo you have to get the bareel counter borred

I just shot 552 in bullseye match on Friday using Lapau standard plus with no malfunctions competitors were shooting with walter sp & Hammerlis second plce was walther @538

There is another option, via Teflon flat rings or rubber o-ring, about 1-2mm thick, at the front of the barrel against the sight block, works for me, and no alteration to the gun.
