Discovery recently updated their premium scope ring and scope mount offerings with their new Lightweight Scope Mounts. The “Lightwenght” typo in the first batch of boxes was not an intentional Trademark name. I pointed this out to them to their embarrassment but I won’t judge given the number of typos in my articles.

The rings are made of 7075 aircraft grade aluminum and make extensive use of lightening cuts to reduce the weight. Technically these aren’t cuts but milled indents into the surface that do not go all the way through. This allows a thin wall of material that helps keep it stiffer.

The mount comes in 30mm, 34mm, and 35mm tube sizes in 1.5″ center height and higher profile 1.93″ heights. Its my understanding that more SOF trainers prefer higher profile mounting of optics to promote a more heads-up shooting position for operators. Discovery also offers mounts with a 20 MOA tilt for long range; the mounts I tested were standard 0 MOA.

On close surface inspection the milling and construction appears of high quality. The mounts have recoil lugs, use Torx screws (star), and a unique indexing pin on the rings which in theory provides more precise alignment of the ring tops and additional stiffness without having the rely on the quality and alignment of the screw/bolt supplier. Using my Monstrum laping kit, I found the mount to be nearly perfectly aligned, requiring no lapping (Those competing in ELR will probably still want finer tolerances). Overall the mounts look as good as those made by big brand mounts for a lot less.
