I’m fascinated by the 300 Blackout. But I keep hearing conflicting stories about switching from subsonic to supersonic ammo.
The manufacturers say their rifles will work with everything. But lots of posts say they need to be tweaked to work with one ammo or the other, you can’t just switch magazines.
1) If you do need to tweak an AR to work with different power levels of ammo, what’s the easiest way? Change out the buffer spring? Install an adjustable gas block?
2) If an AR is set up for subsonic, can you fire limited amounts of supersonic though it reliably?
3) I’m looking at a rifle, but any difference with an AR pistol?
I’m considering getting either a Ruger AR556 or a S&W M&P 15, so I don’t have $2k for a custom build. Or would a Mini 14 be better for switching between power levels?
