Sig P556 - Velocity

[ADAMS]

I'm curious what velocity people are actually getting from the P556 or, alternatively, out of a 10" AR pistol whether DI or piston.

Thanks.

Never chrono'd mine, but I'd take a SWAG that it's VERY close to the same velocity you'd get our of a 10" AR SBR.

Check this thread: http://m4carbine.net/showthread.php?t=38754 It's going to be a bit slower than that, since they're using 10.5" barrels.
