A solution to a problem! This scope and mounts will fit the Airsporter mark 2 with the 4 separate scope grooves. The scope is a long eye relief so therefore it fits properly on the rifle without you having to crane your bonce forward! The mounts are blued steel SAKO mounts that have been carefully modified to fit the Airsporter. We are always looking for better solutions, at this time this is what we have come up with. This is a one off, these mounts are vintage ones that we do not have any more of. Scope screws are slightly knurled. Obviously the wrong screw driver has been used otherwise in very good condition. £85.00 Order code B411
