Anyone know of a source for smaller orders (e.g. at most 5 at a time) of boxes that are sized appropriately for an AR upper? The factory Colt box has external dimensions of 30.5x5x3 which seems ideal for standard length barrels. I'm looking for boxes for 11.5" barrels, so external dims would be roughly 22x5x3.
I'm aware of this place, though I haven't used them: https://www.uline.com/product/Guided...S%2c25%3b1%3bS
Seems like they're more geared toward bulk orders. Similar results on amazon are the same.
This is for storage not shipping so lighter weight also works, doesn't have to be 200lb test.
