I understand why the OP (
@inseconds99 [back in 2015]) might have decided to split it up... This thread's about making this little doohicky work (and compare it to other gadgets out there).
It's cool. I've already been censured by the moderators on Mr. Stodard's thread (I got gung-ho about discussing practical firearm safety... and that's a no no).
Indeed. I'm going to cool it with the purchases until I let the stock tube settle in. I was expecting a bit more printing on the tube... I found a faint code number (picked up by my iPhone). It has no other markings.
I'll fantasize it being some NOS pulled from a NORAD, GoldenEye, or the DEW line facility...
