Description
The Infinity 556K - by customer demand. It actually wasn't something we planned on making, but the Infinity 7.62 was so awesome people begged us to do a 5.56 version, so here it is. And yes, you can use it on 6mm. The Infinity 556K is printed out of Haynes 282 - a superalloy that's even tougher than Inconel.
