Okay I have a CVA Elkhorn pro the nipple thread is 6x1 all the ones I ordered online that are 6x1 screw into the beach plug just fine but they are too short when you put the cap on set the bolt pull the trigger all it does is put a big dent in the cap what is the difference in the CVA nipples for their rifles made in Spain that is where this one is they also take a 6x1 thread
