I bought a two-piece Sportmatch mount without a removable arrestor pin from a reputable dealer(I was under the impression that the mounts had integrated arrestor pins). Are recoil stops/arrestor block/pins not necessary for the HW97K?
I would rather spend an extra couple of bugs and get a scope mount with pins. It will just save you lots of fustration later because you will start to shooter bigger groupings and after two or three weeks of fustration relies that it is the scope that moves.
The HW97K has three holes ontop for that purpose. My advise, use them.
For what its worth I have not had any problems in the past using two piece Sportsmatch mounts on HW77's, although I have always used the arrestor pin fitted into one of the holes supplied on the action.
A one-piece mount would generally not require an arrestor pin due to the greater clamping surface.
Also have a look at this thread, it may be useful: http://airrifle.co.za/forum_viewtopic.php?6.14203

i've got the cheaper hawke match one piece mounts on 2 of my springers.....with pin on the 97K and pin moved on the diana. never moved.
my mates's got the dampa mount on his TX200HC FAC, no pin......20 min into the zero session, 1/5 of the mount came off the rail. i think the trick is to degrease the clamping surface thoroughly.
One of my spring rifles is fitted with two piece mounts without an arrestor pin - it is my Mk1 TX200, which does not feature arrestor pin holes in the action. I have not experienced any scope creep on this rifle.
Which model of Sportsmatch mounts do you have as IIRC both the standard medium/high types feature arrestor pins. If the extended reach form then I am not sure if they come with pins or not.
