I recently picked up a brand new Saiga 12. (IZ-109) I got it home,wiped the cosmoline off, applied a coat of BF CLP, then proceeded to field strip it so I could put a drop of oil on each rail. I noticed that when I reassembled the gun and put the dust cover back on, that there is a little back and forth play with the dust cover. I also have a Saiga rifle, and its dust cover does not do this, it fits very snug. Anyone else have an S-12 that does this ? Is it something I should be concerned about ? Would something like this be covered under warranty ? How long is the factory warranty good for ? Thanks in advance.
