Neat. 300 blackout can be hard to tune, since it's meant to be a CQB weapon that fires subsonic very quietly but can also run supersonic to reach out to 300 yards. A piston makes more sense, since tuning isn't an issue here. Of course, it's a Sig, so that's counterproductive to reliability.
A few points though: 1.) The HK416C project was cancelled. HK deemed the short buffer setup too unreliable. 2.) Honey Badger don't care. -W |

550~600 yards for supersonic easily. subsonics, about 200 yards.

300 blk supersonic rounds have the same trajectory as the 7.62 ak round out to 550 yards out of a 16 inch barrel.
Not as flat as the 6.8 (few calibers are), but way, way more versatile and affordable thanks to the different bullet weight and loads from sub to supersonic, it goes from 115 to 220 and everything in between. |

If you manage to fabricate a receiver, build the "rifle" without a stock, afix a bullet button, run 10 round magazines, and call it a pistol. Sure!

You can shoot to 220 yards with 300 BLK with no sight adjustment or compensation needed. 6.8 gives a 17-40 yard additional max point blank range.
At 300 yards, a 125 grain 300 BLK has more energy than the popular 85 grain TSX in 6.8. But sure, there are also 6.8 bullets with higher BC also. |
