Poor product - ProMag Saiga 12 Gauge 5-Round Shotgun Magazine

Overall I was not happy with these due to two main issues. The first was that they do not fit the Saiga out of the box. I had to file off a significant portion of the front notch to get it to slide into the mag well. The second was that after the 5th round, the guide seems to get stuck and failure to feed occurs. This happened for every single one I bought. Unfortunately due to having to try to modify these to work, I am unable to return them. Unless they fix these issues, I would avoid these.
