Bill. Uline 36x6x6 inner box, 40x8x8 outer and get a roll of corrugated dunnage. Oil the gun lightly, wrap it in cling (the pcs) Then wrap in dunnage corrugated, then into the 36 box, that goes into the 40 inch box and fill the voids with mor eof the corrugated dunnage. About $5 in boxes and tape. But it qualifies as the double box. Never had a failure or a claim. Picture the parts and wrapping as yo ugo and save the pics till the gun arrives at destination. If you are giving 3 days, the gun has to be wrapped the same way coming back. Insure obviously
Good stuff and you cna always use left over boxes in your bus.
The boxes come 25 to a bundle
