It is really simple to make a saiga 12 extremely reliable. I have owned 5 at least and 2 fed well out of the box. There are 2 issues that affect the saiga. 1st is the gas port. Early saiga guns had 1 or 2 holes, recent guns have 4. This seems like a big issue but it is easy to fix and you can get the gun to run with 1 hole. The most important thing on the saiga is to buff the contact areas of the bolt and bolt carrier. This is simple to do with compound and a buffing wheel and there is little to no risk of making a mistake. If you buy a vepr you may still need to do a fluff and buff. I did a saga 12 pistol grip conversion last week and was a little nervous. I found it was easier than working on a 10/22. Cost of s12 $500, cost of conversion and reliability $250 including bad ass quad rail. $750 total versus the rest. it is a question of budget. If anyone out there has a saiga that does not feed and wants to get rid of it, please please let me know. I will gladly take the POS off your hands. I haven't shot the Kriss and I do want one really bad. This being said inside a home my saiga 12 would be much more effective than the kriss. 20 rounds of buckshot is really hard to deal with in close.
