I could see that happening. my bro had his apart and cleaning so i took a pic of that area. They got a little to much metal out of the bottom area. Didnt find any cracks on this one so thats a good thing. Is yours adjustable? im thinking about a new adjustable tumbler to put in so we can tune the trigger down to our liking. This one was shooting sabots today and the 1:32 barrel flung them out there nicely. CVA should have replacements, if not, i know ebay is full of parts for these rifles.
