The pure blowback carbines have always been a bit of a compromise. In order to balance the recoil forces from the round these systems need to add considerable weight to the carrier and buffer. They also utilize an overly long BCG travel as well. The result being a lot more felt recoil than is necessary.
A DI system is much smoother, has less felt recoil and most importantly from my perspective is that they do not require a buffer. Thus the CCS type of stock can be used to reduce the weight and OAL of what should be a compact carbine or SMG type of firearm.
A 9mm SMG that is the same weight and OAL as a 556 carbine is silly IMO.
Yes they do.
I modded mine with a buffer tube spacer (the quarter trick found on AR15 .com) so the travel just clears the hold open catch. Much better now, very little perceived recoil.
9mm ARs are notorious for breaking bolt catches (I have read), due to the excess travel rear wards and the force coming forward at the bolt catch due to the "run" it gets at it.
