Tough choices!

If you reload, it is a good caliber.

If not, not worth it.

spend a few more bucks and you can get something better, and build it your self

Since nobody answered your last question:

The big advantage to having a 300BLK when suppressed is that sub-sonic loads are really easy to work up for it. And it takes a heavy enough bullet that going so slow only hurts the performance, rather than kill it like some other rounds. If you wanted to do a sub 5.56, you won't get the gun to cycle at all, and they drop like crazy pretty quick if you keep it to mag-length for an AR (e.g. not running 90gr bullets). With 300blk you can run the 208s, 215s, or 220s, keep them sub-sonic, have them fit to mag length, and still have a properly setup gun cycle reliably. They still drop pretty good compared to super-sonic, and all 300BLK will drop much worse than 5.56, but to 300-400 yards its pretty good still. Plus so many people have 30cal cans that it make some sense to use that caliber for the gun to them.

Suppressed 300blk sub rounds are REALLY quiet.

Thanks J. Makes sense!
