IKR! I'm trying to lock 'em up to avoid unauthorized breeding...I swear them things breed faster than rabbits
Will probably go this route. A soft case wouldn't take much room in the safe and you can store a couple, or perhaps 3 Uppers.Bulldog used to make a case for broken down ARs, works great, but discontinued, Midway Makes a similar one, works well. Store two uppers instead of whole AR.
That's what I'm doing now. It really isn't a big deal, but a scoped upper tends to be in the wrong place when moving rifles around.I have a couple of uppers leaning against the wall at the back of my safe.
Interesting solutionsThis gizmo will keep your BCG in that spare upper...
For storage... I put the upper into a VCI bag, with a VCI bore tube. A DRY place is a good idea since plastic can trap moisture.
As for the container... I use something like these. Plenty of room for a quite a few scoped uppers, fill the gaps with mags or barrels / parts.
I throw a few Desiccant bags in as well to help absorb moisture. Bulk purchase source.
