I picked up a saiga 109 a couple of months ago. I've been having problems with it not cycling correctly. I took it on vacation and it was catching every shell. I had taken it out a few weeks earlier and it was working fine. I disabled it and cleaned it before taking it on vacation. I brought it back home and re cleaned it and used a new lube (rem. dry lube) and I took it out yesterday and it is cycling now except for about every 8th or 9th round. Dose anyone know what is up?
