My only concern with Pete's "US Property" marked lowers is completely specific to my personal situation...
The only range I have access to with more than 150 yards of lane is on Fort Benning post! The guys at the gate are DUMBA$$ES! They're civilian contractors, NOT MPs. (The MPs were great, and most were range members).
Sometimes, they say "thanks and have a nice day", but sometimes they say "you have fireams in your car? Sir, step out of the vehicle immediately and keep your hands in view". No consistency, and if it wasn't for the 500 yard range, I wouldn't go.
So can you imagine, during one of their "I don't know $hit" searches, looking at my unloaded, properly stored AR that's marked "US Property"?
Sure, I could try and sue them after I got out of the holding cell, but then I'd miss my whole shooting day!
I like Pete... I think he's a funny guy, and he's been pretty friendly to me on the phone. Of all the arguing I've seen, and no matter how poorly he may have handled certain situations, I can say first hand that he was 100% correct about the matter in question.
