The Bisley HOP77 is a one-piece cantilever scope mount designed for AR-type rifles running 30mm scope tubes. Manufactured in the UK by Sportsmatch and sold under the Bisley label, it solves the short-receiver eye-relief problem common on AR15 platforms by positioning the scope 63mm (2.5 inches) forward of the attachment point. The full-length Maxiclamp Picatinny rail section, measuring 55mm, grips the receiver rail across a large surface area and is secured by two knurled thumb wheels to resist movement under recoil. The ring cradles any 30mm main-tube scope with an objective lens up to 50mm diameter, and four Allen-head ring bolts clamp the tube securely – an Allen key is supplied. CNC-machined throughout, the mount weighs 170g and sits at a high profile to clear larger objectives. Total mount length is 120mm.
