First of all let me say it does come with everything pictured in the description (Ball head, Universal Saddle Clamp, and QD Picatinny Rail clamp) which is confusing because the parts seems to cost more individually so this is a good value. The bottom of the ball head is threaded for a 3/16-18 on bottom so it is perfect for use with a Bogen 3221 or Manfrotto 055 which can be picked up relatively cheap used. The clamp and picatinny rail adapter is attached to the ball head using a bolt (5/16" or 1/2" I believe). As for the review.. I was looking for an alternative to the HOG saddle. Even the PIG saddle is a bit expensive for me so I decided to try out the KZ offering here. Taking it out of the box, all parts feel robust and well put together. I clamped it to a few rifles (R700 with AI chassis, Savage MKII TRR-SR, and AR15 (MK12 Mod 1 build) with round PRI handguard) and it held all rifles very well. The ball is adjustable for tension and could also be set to lock the rifle securely in case I need to walk away to take a picture for instagram. When removing the rifle is where I found its fault. If you look at the HOG saddle it has one clamping knob and two smooth rods that allow it to slide nicely when the saddle is clamped down. This however is built with two knobs that are set on threaded rods. As you tighten the knobs the plate on the clamp starts to become misaligned and since it is simply a piece of aluminum with holes drilled through it, the thread bind to the edge of the hole. This is fine until you try to remove the rifle. After unscrewing both knobs the clamp does not want to open. I found that I could get it to un-bind as soon as I stick a screwdriver in there and pry it a bit. So I guess I would have to carry around a small pry bar when I use it. I will try greasing the holes to see if it helps. Another idea I have is to modify it with stainless steel bushings or bearings. I may update this review at a later time when I do. I have not had a chance to shoot with it yet but I don’t see too much issues as a lot of hog saddles out there are home made and not as robust as this anyways. I also have not tried the pic rail clamp as none of my rifles have a pic rail under the handguard. It is a good value for the money (compared to the price of similar products out there) but I wish they looked into this issue before releasing the product to the public.
