Required fitting, but worth it - FAB Defense AK-47 Quick Deployment Bipod with Integrated AGR-47 Pistol Grip

I read that it’s hit and miss regarding compatibility, and the description even says adjustments may be necessary. I spent 30 min with a sharp pocket knife and have a perfect and very tight fit on my Zastava M90, which shares hardware with the M70. Although adding weight, the balance it creates negates anything negative about the feel. Seems solid.
