Also known as: Heym SR-21, SR 21
Overview
The Heym SR21 is a German precision bolt-action hunting rifle built by HEYM in Gleichamberg, Thuringia. Its bolt locks with three solid front lugs, reducing bolt lift to 60 degrees and keeping the handle clear of a low-mounted scope. The rifle uses a modular switch-barrel system in which the barrel and receiver are exchanged as a unit, a free-floated hammer-forged barrel, resin-and-aluminium pillar bedding around the recoil lug, a single-set trigger, and a three-position bolt-shroud safety. Chambered here in .308 Winchester, it is offered across a wide range of standard-length hunting calibers.
