Greetings, I just logged on and wanted to add my answer and experience placing a scope on the CZ 527. 7.62 X 39 carbine. A friend let me fire his CZ 527 using the standard iron sights. I was impressed with the accuracy and handling of the wonderful rifle. I called the CZ dealer where I purchased the rifle and ordered the standard issue CZ scope mounting 1 in rings. They are very strong and around $50..... Give or take a few bucks. I then did a significant amount of research. I wanted something that was reliable, well made and not outrageously expensive. I have other scopes and have always purchased on the upper end such as a Trijicon ACOG ( a wonderful scope). For the CZ, I purchased a "Redfield Revolution 3-9x40mm"( Leupold & Stevens brand) I was able to get it on sale and Bass Pro matched the price and it was in stock. The scope just fits the rifle without Erving the front sight. This scope does a wonderful job! Just this week I took the CZ to the range and fired 40 rounds of PPU brass 7.62 x39. All 40 rounds hit center mass at 100 yards. 80% were within 1.5 inches of the bulls eye. A very accurate and easy to shoot Firearm. I was so impressed with this rifle, I purchased one for my son, also a retired vet, when he graduated from nursing school. He mounted the Leupold equivalent and removed the forward sight (easy to do,also). Hope this helps....
