I’ve been using the Spuhr Ideal Scope Mount System (ISMS) on my rifle for the past two years. Equipped with a Picatinny rail interface, the ISMS is machined from a single billet of 7075 Aluminum and uses stainless steel screws.
The ISMS offers a series of unique features. A built-in scope leveling system ensures the scope is properly installed. A level at the rear of the ISMS allows the shooter to ensure his rifle isn’t canted. Multiple mounting surfaces provide a wide variety of options to mount red dot sights, night vision, lasers, illuminators, lights and cosine indicators. Horizontally cut rings allow unobstructed view of the scope turrets.
ISMS mounts are available in 0 and 20 MOA cants for 30mm, 34mm, 35mm and 36mm scopes.
I liked the Spuhr ISMS when I first started using it. Two years later, it’s become my clear favorite. I no longer have to worry about a canted scope installation and find the integrated level easy to use in the field. The low profile of the scope rings allows a clear view of the scope’s adjustment knobs. Plus, I haven’t noticed any ring marks on any scope mounted in the ISMS.
The Spuhr ISMS is available from Brownells.
