I need a 77/22 22lr. breech block to convert from 22mag. to 22lr. but no one seem to sell them.
Any ideas?

I just measured the bolt face on a LR Bolt and on a Magnum Bolt. The opening on both is .285. The difference in the two bolts is the length of the groove on the bottom. The magnum bolt looks larger, due to it being closer to the lens. Otherwise they are the same.

The depth and width are the same. The bolts show 2 grooves. Notice the difference between the lower groove on each of them. The groove on the magnum bolt does not go all the way to the face of the other half of the 2 piece bolt. The half with the locking lugs.
