Makes rifle jam - FAB Defense AK 47/74 Aluminum Tactical Rail System

I bought this item from midwayusa.com and installed it on my rifle. it looked and felt great. after firing 10 rounds I had my first Jam from my AK. thinking it could of been issues with the ammo, magazine, the moon, etc. I cleared it and used a new magazine, after 15 rounds I had another jam. looking very closely while shooting. the spent case was hitting the top of the rail and causing it to come back in the ejection port making the rifle jam up. I was not pleased by the performance of this product. with cool looks being its only pro, don't buy this over priced rail.
