Their .308 match grade carriers are the nicest I've used. Certainly plan to grab a few of these.

I might not be an admin but I’m the resident asshole here. Lol

You are in for a world of pain if ANYTHING said on this forum upsets you. A lot of forums I’m on, by the second screwed up post everyone would have piled on.

But that temper tantrum is hilarious. My kid just turned 9 and outgrew a good tantrum so I miss them.

I probably get more shit from UW than anyone on the forum... I don't frequent here as much as I used to but I still get it.

PS: Please hold your breathe while you wait for John (or anyone) to give you a call. That'll solve the problem itself...

Tell him about that upside down muzzle device story...

Or should we let Uwone tell it?

And you know I give John more shit than he's probably used to.

Zhou, if you want to stick around and actually have fun and learn a thing or two about your gun, have at it. We're a fun group. If you want to rage quit, that's cool too. It's nothing personal.
