Guide rods have issues<\/h2>\n

Link discussing old guide rod design: https:\/\/www.reddit.com\/r\/AR9\/comments\/1fzxdmu\/cmmg_9mm_dissent_broken_guide_rod_within_25k\/<\/a><\/p>\n

In the event that link is archived, here is a picture.\u00a0 It sounds like customers need to reach out to them if \"\"<\/p>\n

Even with the new design, looks like the guide rods are still failing: https:\/\/www.reddit.com\/r\/Cmmg\/comments\/1mf8s8h\/dissent_mkgs_9mm_spring_rod_failure\/<\/a>

Another case of the Gen2 guide rods failing:<\/h2>\n

‘Bumper’ gets destroyed:<\/strong><\/h2>\n

See this link:\u00a0https:\/\/www.reddit.com\/r\/Cmmg\/comments\/1p4f9rs\/9mm_dissent_bumper_failure_after_1000_rounds\/<\/a><\/p>\n

Not readily FA \/ FRT \/ SS capable:<\/h2>\n

Yes, I know there is a company working on a linkage to get the Dissent to work with a FRT \/ SS but it results in a bullet hose of over 1000RPM and nothing you can do about it.\u00a0 IMHO, that gets old fast.\u00a0 That is too fast to get controlled bursts out of.<\/p>\n

Issue with lack of tuning .45 Dissent:<\/strong><\/h2>\n

In the following link, someone is having an issue running heavier bullets in his .45 Dissent: https:\/\/www.reddit.com\/r\/Cmmg\/comments\/1g4hv26\/tuning_suggestions_for_suppressed_9mm_dissent\/
\n<\/a>“I can’t run 230gr reliably. 200gr is fine.”<\/p>\n

My comments in a Youtube video below were deleted by CMMG where they said that the older CMMG ‘buffered system’ would work with .45 SMC but you can’t run that in the newer Dissent.<\/p>\n

\"\"<\/h2>\n<\/div>\n

Being bufferless also means not as smooth:<\/strong><\/h2>\n

Even beyond all these issues, it will never be as smooth as a buffered setup as I demonstrate in my high speed video here:<\/p>\n
