My 14.5” is my favorite AR-15 period. It is SUPER soft. I also have a LPR, and a Legacy gun in KAC, and several other AR’s in different brands.
My shooting partner, and the guy that got me into KAC to begin with pushed me hard towards a 14.5”. Glad I listened. I can’t imagine this is a decision that you will regret. Besides, it’s the “first” KAC, not the last or only. I’m running my 14.5” with a NF NX8, and it’s awesome all the way out to the limits of 5.56. My overall favorite AR I’ve owned.
