Scope base stock is machined to MIL STD 1913 Picatinny dimensions for fabricating custom rifle or handgun optic bases. Pre-cut cross-slots speed the job and allow use of any Picatinny scope rings. Ideal for quickly building a versatile base for a gun with non-standard hole spacing, rather than drilling new holes in the receiver. Available in pre-hardened steel or aluminum, both with a matte black finish. Bottom of the base is flat, so it can be radius cut to fit any receiver contour.

SPECS: 4140 pre-hardened steel, blued, or 7075 T6 aluminum, hardcoat anodized, matte black. 7ѕ" (19.7cm) long, 1" (2.5cm) wide base, ѕ" (1.9cm) high. Nominal height of base is .735".
