Suppressors and SBRs are overrated. The main appeal is the government not wanting you to have them.
I have several suppressors and a few SBRs, the only one I use anymore is my 9mm with a can because it’s still short and actually quiet. I have a .22 SBR with a can, but I don’t really use it.
I don’t even own a threaded barrel for a pistol anymore even though I have suppressors that could go on it.
Short rifles are obnoxious without a suppressor and still not hearing safe with one, and when you put a can on it becomes the same length as a full sized rifle. Rifle cans heat up very quickly, becoming a hazard, and causing mirage.
Not to mention any of the tuning required to get guns to run good suppressed, and increased gas to the face with a lot of rifle cans.
Fair enough, but they're still useful in their own right. The issue with all this stuff is that people say it's more versatile and good than it is, when it should actually be used for rather uncommon tasks.
If you're doing real shit then they're quite useful, but for regular things they're not that important. If you're indoors or in dense areas with sub 300 yard ranges an SBR with a can is 100% worth the drawbacks since a rifle barrel and can would be too difficult to use, and no can indoors is terrible. If you're fighting and don't have a can you're sorta fucked. Even though your shots are still loud, they're pretty much untraceable at range due to the sonic crack of the bullet echoing before the muzzle report even reaches the target. Sound isn't the only thing either, if you're running NV or just in a dark area, you don't want a shit ton of flash. Even if you're not actually fighting but you're still out at night, you don't want to daze your acclimated night vision.
For sound stuff, it's like asking if you'd rather get hit by a truck or a bike with everything but rimfire. Sure you'll get cut up and break some bones, but it beats the hell out of being misted.
SBR with can is more useful within a set range than a rifle with can, but
It's really the maximum capability for the minimum package, since if carrying bulky shit in tight areas didn't suck then then it wouldn't even matter. Same reason you carry a pistol and not a shotgun really.
If you're just on a range then whatever, use plugs+earmuffs, but if you're hunting and don't have earpro a can is pretty sweet. A 300 win mag will fuck you up compared to one with a suppressor.
