In the past, when I’ve sold an upper (like I just did with my RRA), I usually put them in a box that I got from Bravo or LMT or whatever new upper I had just bought.
Now I am going to sell a couple uppers but do not have replacements. Where can I get those awesome square boxes used by places like BCM? I’ve gone to the hardware store and USPS, but the closest I can find are poster tubes which don’t work with my FSBs…
Any thoughts on the best way to ship these – without having to buy another upper just for the box?!
I acquired one from the UPS Store. It was the right length but about 6 inches square so I used some bubble wrap and packing peanuts to fill the space. Worked nicely and was free.
