The Sadlak Brookfield-type scope mounts are a positive 3-point design that allows removal and re-assembly without losing zero. The Picatinny-style rail is machined to Mil. Spec 1913 and provides universal scope mounting. The titanium mount is made from an aerospace-quality hot-forged billet (limited production), not from a casting or plate. It is tougher and stronger, yet weighs 40% less than steel. It has a 26-30 Hardness Rockwell C (HRc) and has been surface coated for a non-glare, matte-black finish. This coating increases the surface hardness to approximately 80 HRc, adding to its corrosive and abrasive resistance.The steel mounts is made from stress-relieved 4142 bar stock with a hardness of 28-32 Rc. The finish is Mil. Spec. black manganese phosphate. The aluminum mount is made to the same rugged 3-point contact design from 6061 heat treated aircraft aluminum. The standard finish is black hard-coat anodize. This model is lightweight and is a lower cost alternative that makes it an ideal mount for rifles used in less demanding circumstances or seasonally, as in hunting.All mounting hardware, fasteners, and hex wrenches and detailed instructions are included. Scope rings not included.
