    Worst customer service than ever. Have ordered GL-Core stock with adapter for G3 and received stock with adapter for Galil. I had put a claim to customer service and after one week they are shipped me as they said correct adapter with tube. The problem is that this shipment is still not departed from Israel. Nobody wont reply me on my letters what’s going on. Looks like I am purchased 60 dollars stock for 170 dollars! Great purchase on 1 star only! I am very disappointed in Zahal service now. I Will not recommend this shop now to my friends.
