Most Helpful Positive Review Well made pdw upper from cmmg
If you want a buffer-less pdw length upper under 9 inches compatible with a Milspec ar lower there aren’t a lot of options out there. The only other option with a 6 inch barrel I can think of is the sig rattler upper but those cost about $600 more than this one. Great fit and finish and functions well. If you’re looking to build a super compact pdw the cmmg dissent upper is a solid option. Would recommend.

Love it. Great quality and perfect fit on Dissent lower. No malfunctions in first 60 rounds. Good accuracy with Holoson red dot at 50 yards. Fun to shoot.
