Just what I needed to add a scope to my AK pistol.
Great product from Rapid fire Technology, good product for the money, Just as advertised, Easy to install, only 10min, solid platform.
Great price. Real easy to follow video instructions on youtube. Had it mounted on my pap in 15 to 20 mins. Holds tight. Id add some blue loctite to make sure it stays. Took my pap to the range and it stayed on..
Easy to put on with the help of the installation video on RFT's website. Looks great and functions well. The mount was delivered within 3 days. I highly recommend this product and company!
