Back in the mid 80s and up to the early 90s I worked a part time for Walt Lagendorfer. Walt designed and held the patent for the Rhino Device, 1st gas piston system on an M16/AR15.
Walt was always making some sort of attachments for M16/AR15s rifles. One day he came back from a big Gun Show in Ohio with 3 dozen NIW M60 barrels with bipods and FHs. Walt then designed and we made made conversion kits for the mounting of the M60 bipod onto an M16/AR15 barrel. I bought one bipod and kept one of the conversion kits. Here is a picture of my son,(he is 15 years old in this pic), with a M60 bipod mounted on a pre-ban AR15 Rifle. The conversion Kit caused my groups to open up to 8 or more inches at 100 yards. It was terrible. I still have the conversion kit and bipod but I will never mout it again on a rifle.
