One of the guys at the PD had a real "DOH!" moment a wek ago. We were at the range to sight in the PD supplied Bushy M4 type carbine that Chiefy Warbucks purchsed for him. He's the "team leader" for our new tac-team.
Anyway, he didn't really listen to the recommendations that HE asked for before ordering the rifles. Anyway, he bought two off the rack rifles from a local dealer. They had the Izzy hider on them, the one with three ports at 9-12-3. We were shooting side by side. My rifle, as you can see from the above pics on previous pages has a mil-spec A2 hider.
It gets dark, we do a night shoot. He has a HUGE fireball from his "flash-hider". Nothing but a tiny kernel out of mine. At first, he's convinced it's the ammo. So, I change mags with him, same results. Now, he's pissed because the ploom is so huge it interferes with his sight picture.
hilarious.
