AR Pistol twist rate

[howl]

What is the recommended twist rate for a .223 pistol for 40 to 50gr bullets?

 

[Necrosis]

1/7 or 1/9 are what's readily available and either should work fine.

40-50gr? Why so light?

But does it penetrate bad guys effectively? Usually those bullets are intended for varmits IIRC.

Dang that’s gonna be loud.

Yeah... if that's your main concern... I'd be looking at a PCC... CZ Scorpion or MPX... not a 5.56 platform

Gotta choose them battles.

Honestly I don't think it would even matter at the distance I think your talking about... I'd rather use suppressed 300blk or 9mm at that point!

300 subs would be a solid choice too.

subsonic 300 or 9mm will blow through walls and out your standard stick built. No point in killing the baddies if I also kill the family. Options are shotgun with birdshot or suppressed AR with V-Maxs.
