If a semi is having problem when a Krink is attached to it, then there's probably something else wrong with it. The main advantage of the Noveske/Krink breaks is that they can help SBRs cycle more reliably, but they have other advantages that can be beneficial on any barrel.
First off, they are a good flash supressor (it can be argued just how good they are at flash supression, but they are better than an A2, although not quite up there with phantom/vortex FHs).
They act as a compensator. Admitedly, recoil on an AR isn't really an issue for most people, but sometimes every little bit helps.
They redirect the muzzle blast. For me, this is their biggest advantage, and the reason I have them on my bullpups (the muzzle is a lot closer to your face on a bullpup). The fact that they also redirect some of the sound down range doesn't hurt either, and I've had several people at the range comment on how little they are affected by muzzle blast when I have the Krinks on a gun.
They do add weight to the front of a barrel, but it isn't really that noticable unless you have a lightweight barrel, and I find that the extra weight helps with muzzle rise. Personally, I like them, and think the pros outweigh the cons, but YMMV.
