My Merkel has developed a rattle in the buttstock. I haven't investigated this yet but suspect it may have a recoil reducer installed. It's a model 140A (I think) - did they come original with the reducer fitted? I bought the rifle second hand.

It doesn't seem to be end-to-end but more side-to-side rattle, which means it's loose but not sliding backwards and forwards much (yet).

I presume that it shouldn't take too much to hold the reducer in position. I've heard people use epoxy or even expanding foam but these sound to be at either extreme (ie from semi-permanent to slowly destructing). Any suggestions on how to otherwise hold in position?

(Another issue - After our BGR match, for which ejection worked perfectly, I went on to fire the remaining 6 rounds for practice and did so by single loading but firing from alternate barrels, and I noticed the RH ejector would "uncock" after firing the LH barrel and opening the action - I noticed both ejectors sticking out the same amount. Normally the ejector on the unfired barrel doesn't actually eject or stick out as far as the one that has ejected. This happened some time ago and resulted in a fail to eject - I used lubrication to fix it that time. I guess that there must be a catch that jams up when it loses oil. I would like to maybe file/sand to help with this issue but am terrified of pulling apart the ejection components in the forestock without any instructions. I can imagine springs making noises as they bounce around the loungeroom. Anyone have instructions on how to do this?)
