Beautiful G-11! I own the G-11, K-11, and K-31 and the G-11 was my first Swissicon rifle. Word of warning: be careful as to the diameter of the bayonet. The G-11 has a muzzle diameter of 15mm, most other bayonets have a diameter of 14mm. It is pretty difficult to find a bayonet for the G-11. I believe the Model 1889 bayonet is really the only option. I spent a decent bit of money on a nice bayonet with a diameter of 14mm before I had acquired a K-11 and K-31. I was not very happy, but I had saved it long enough to be used on my new rifles. Here is a good resource:

- The M1899 bayonet also will fit it, but it comes in two diameters. Just use a caliper to make sure it is the correct 15mm width.
