To be fair, there is plenty of “anti-hype” too. And not just for Impacts but with anything. People that dislike product X for one reason or another. Impacts are popular for good reason, but for as many guys that swear by them (myself included), there are plenty of detractors too.
Saying it's "overhyped" is not mutally inclusive of being a detractor.
I say that the Impact is overhyped because quite frankly, how can it not be with how much it is talked about? Especially on Facebook - I dare anyone go on one of the many precision rifle Facebook groups and suggest that other actions are even in the same league as the Impact - the echo chamber is strong there. Hell, I had Jim See all up in arms by suggesting some other actions are every bit as good as an Impact. Had to remove myself from FB precision rifle groups because of all the retarded rhetoric that kept getting posted.
Regardless, as good as the action is, it is talked about like no other action is in it's league. Sorry, but while it's a great action, it's not the be all end all. It's one of the finest renditions of a rem700 action - I will give it that. It is very refined. But there is nothing groundbreaking that makes it the obvious best choice action - it has many peers that are in it's weight class.
At the same time, I have recommended to many people an Impact action. I know it's a great action, and I know I would be more than happy if it was the heart of my PRS rifle. In fact, I almost bought one. I would hardly call myself a "detractor".
Is it overhyped? Yes. And I can't stand blatant group think rhetoric. But it is a good action.
