shuter Posted January 22, 2010 Share Posted January 22, 2010 Hello all, first post here. Am looking at new M4 at local dealer. Seems like I heard a few years ago about problems with M4 "bolt carriers" cracking, and having to use low pressure shells? Maybe I'm remembering wrong. Does the current generation M4 have any durability issues such as these? Has Benelli made any changes to the design since inception? Thanks so much in advance for your input. I like the ability to customize these as well. Kinda like a shotgun version of the AR! There seems to be an entire cottage industry that I wasn't aware of. see ya Quote Link to comment Share on other sites More sharing options...
