| Need to bounce a question off you guys. I've never had an issue with any of my converted Saigas, except for my .223. The gun runs about ~90% or so, but occasionally, usually once every other mag I will get a double feed. I have the dinzag bullet guide, it's installed right and in the right location. I thought it may be my Beryl mags, so I picked up a Galil steel mag and got two double feeds on the first mag. So, it's something else. What usually causes double feeds in .223? Is the mag sitting too high? Do I need to raise my BG up a little or something? I would presume the only way you could get a double feed is if two rounds are able to reach the BG at the same time, or if the bolt is able to somehow catch two rounds at the same time, both would be the mags are sitting too high. Sitting too low isn't a problem, that can be modified, but too high? |
| It's probably the bottom edge of the bolt digging into the round underneath the round being fed and stripping it out of the mag. I had this problem with my Saiga .223 with Beryl mags and brass casings and have read a number of threads of others having a similar problem. The solution is to soften up the bottom edge of the bolt. However, if you file or buff the part and remove to much then you have FUBAR'd the bolt. I think the best solution is to let it break in using steel case. With steel casings you will probably see a scrape accross your casings where the bolt is dragging. But it shouldn't double feed a steel cased round. At least mine doesn't. After awhile it will smooth itself out. |

So you just removed some material from the bottom of the bolt? How much? a few thousandths? |

Quoted: A picture of a double feed? Quoted: Quoted: Post a pic of your issue before you break out the Dremel. A picture of a double feed? It's kind of hard to fully understand what's happening without pictures. Also be prepared to take additional pictures once you post the one of the double feed. We will need to look at certain areas of the rifle to determine if anything looks out of spec. |

So you just removed some material from the bottom of the bolt? How much? a few thousandths? My understanding is that the problem has to do with the sharp leading edge of the .223 Saiga bolt. An SLR 106 bolt for example has a softer edge. I chose to just break in with steel cased ammo rather than try to camfer that bolt. |
