I bought this brand new, but decided at the last minute to go with the Chaos Titan full length rail instead so letting this one go. Never installed, only taken out of the packaging for pictures. These are THE finest rail system you can buy for the Saiga 12. Fit and finish is like no other rail I've ever seen. Pre-drilled for HK sights or put any other picatinny rail optic or iron sights on it. "Made for Saiga 12, Chaos Extended Rail System (CERS) is manufactured to highest standards in the industry. Our MIL-STD-1913 rails are made from aircraft grade 6061 aluminum alloy. Rock solid with the top rail extending over 13" in length. Hard coat military specification MIL-A-8625 or Type III non-reflective black. Already tapped for sights to be mounted. Weight: 17 oz." I will accept credit card payments thru a disreet Paypal transaction with buyer to pay the 3% fee.
