From a B-ARFCOM thread today. I sure wouldn’t have thought this would happen.
Well, this is a new one to me.
Went to install a MBT in a Sig AR and found this when I opened it.
I’m thinking: WTF is that? Looks like bugs. No. That’s a fucking grain of fucking rice but how in the hell.
So I slipped the upper back on and looked. And realized. Yep. That mag well is a perfect hidey hole for my nemesis to hang out and store food. Safe has a couple holes from previous mounting.
