Don't know if you've heard of this before or not, but X-Products makes an AR upper designed to fire full cans of soda (among other things) using 5.56 blanks. I've been watching videos about it for a few years now and it looks fun as hell. But for the MSRP of $365 (used to be $400), I've always passed it up for a better purchase like a new gun, scope, ammo, etc. Now, they're on gunbroker for about $230 and is making me reconsider getting one.
This is definitely a personal preference question, but what do you all think of it?
