Experience the precision accuracy and lack of recoil of the Rare HY-Score 820SM name .177 Pellet Airgun, with the Giss Recoilless system a top-tier choice for serious seasoned competition match shooters and beginners match shooters.
This rare rifle find has been resealed and tuned at Airgunwerks by owner and National Competition Match Airgun champion David Slade.
David having worked as a Master airgun gunsmith for Beeman Precision Arms and is considered the expert for Giss Recoil Systems precision systems.
With its fixed barrel design and side lever cocking mechanism, this air rifle delivers exceptional accuracy and a consistent shooting experience.
The renowned Giss Spring System, imported from Diana of Germany, the system used in the renown Diana 75, ensures a smooth and reliable performance, while the opposing piston design eliminates recoil, making it ideal and specifically geared for match competition shooting.
It is also great for fun plinking all day with an easy cocking side lever which eliminates shooting fatigue!
This elegant weapon boasts a walnut stock, which has a small mark (see photo), that adds a touch of classic appeal to its modern craftsmanship.
Its accuracy and consistent velocity are complemented by a range of features, including no recoil, and a sidelever for easy cocking.
Unfortunately, it did not have a rear peep sight or front tunnel sight when I purchased this airgun, it has a dovetail for attaching a peep sights and front sights or a add a rifle scope.
This HY-Score 820SM is a testament to advanced engineering and a pleasure to own and shoot for any airgun enthusiast. Of note this gun has the HY-Score name and logo making it an extremely rare find especially for Giss System Match Gun collectors!
