PLEASE NOTE: - These rings fit Picatinny Rail only, NOT Weaver.
These Blued Steel Picatinny Rings are precision made by Contessa Alessandro & C. s.n.c. These parts are precision made to fit onto picatinny rail systems with the supplied wrench. Each ring is tightened with 4x screws, which offer a very firm and reliable fixture. The ring is attached to the picatinny rail with a hex nut.
