I have two of these mounts. They are often used on AR-15's but mount to any picatinny rail. I bought them to move the scope on my bench-rest rifle up and back. They come with inserts so they work with either 1" or 30mm scopes and they are very sturdy. I am selling them because I chose to shoot from a different bench position. One set is brand new and is available for $125 shipped. The other set was mounted on my rifle and looks like new (It is the one in the photos). You will need Torx wrenches for this one so I'll knock off 5 bones, $120 shipped. I prefer PayPal but will accept a postal money order or even a personal check so long as you don't mind waiting for it to clear. I will add photos shortly. https://www.jprifles.com/buy.php?item=JPFTSM-30/1 Thanks, Dave.
