This is a new scope mount for Mauser small ring actions as well as many other C&R rifles. This is a side mounted rail system that allows the use of a military bent bolt or in some cases a straight bolt. This will also allow top crests to be preserved. This is a very modular system with both the top rail and side rail being able to be flipped around, this allow the scope to be moved either front to rear or from side to side to make more clearance for the bolt handle. The picture above shows the scope mount at its furthest to the left position. The mount does require the receiver to be drilled and tapped on the side, the threads are 8-32.
Large ring Mauser mounts are in production and will be done in late August. They are very similar looking but have some slight changes to clear the stepped front ring.
