I use bipods on pretty much all of my AR's. Keymod handguards are my preference. I have used many different Keymod bipod adaptors over the years. Some have been junk or crudely machined. Some are just flat over priced. I stumbled across this adaptor on EBay, from the pictures it looked well built and machined well, so I ordered it. Had it in three days, the machining and finish are exellent. It's solid and well built with a rotating sling swivel stud. Can't go wrong for $10.88 Shipped.
The package says "Vism, A division of NcStar".
