Evolution Outdoors Scope Base Features The Evolution Outdoors Scope Base is machined from domestic 6061 T6 extruded aluminum giving it the strength to handle recoil while keeping added weight to a minimum at just 2 ounces. Its one piece Picatinny rail design spans an overall length of 6.670 inches providing ample real estate for ring placement and eye relief adjustment. The 0 MOA configuration keeps the sight line parallel to the bore suiting typical hunting and target ranges without extra elevation correction. A matte black finish rounds out the base keeping glare down in the field. Ambidextrous by design this base mounts the same way regardless of which hand the shooter favors and it ships with #8-40 x 1/4 screws plus a T-10 bit for installation. The mounting hardware is torqued to a specified 20 in/lbs giving installers a clear benchmark for a secure repeatable mount. Built specifically to fit the Henry Supreme and Homesteader rifles it bolts on without reshaping or fitting work. The Evolution Outdoors Scope Base is available for sale at GrabAGun for Henry lever gun owners ready to add a dependable Picatinny optics platform.
