NiBoron is pretty slick. Slicker than chrome. A good dose of FP10 has always been used on all mine. If you mean the bolt moving inside the carrier being tight there are no slick ones. They are tight because the rings have to wear in no matter if they are full NIb or chrome plated.

There is one called Cerraplate that is ceramic in some coating that is pretty slick also. Ritch and I sold about 300 of them during the panic at dealer cost to the guys. A little oil on them and they are as god as any greased pig. There are produced by an OEM manufacturer in Kansas, Signature, and I really like their products.
