I recently purchased a used Brocock S6 Contour (the company verified by serial # that it was built in 2015). It is a dandy rifle, very accurate and super lightweight.
[I mistakenly thought I was] having some trouble with the magazine indexing properly.
Update: I was not cycling the bolt in the full "U" pattern which is necessary to properly index the magazine. In other words, dumb operator error!
Here's a close up of the "U" bolt pattern and a full sized picture of the S6 fitted with Burris signature airgun rings and a Leupold 3-9x33 EFR.
