I am not seeing my bullpup Remington 870 or the Kel-tec sub2000 with quad rail on it. It’s very possible that I am overlooking them right in front of my face, but it’s also possible that I lend them out for somebody to try and forgot about it. If you have one of those on hand, please let me know privately.
I had a similar mystery recently, when a pistol disappeared. Turned out that a helpful friend put it into a case with another pistol going to a gunsmith for repair. The gunsmith didn’t ask me what the second pistol was for until I called about it.
So, just in case, I am checking on the two items I temporarily can’t locate.
