M16 Build Barrels

I printed most of a full scale replica M16a2 only to find that at the end, there was no barrel or parts to actually attach/glue everything together. I quickly built these (set of 4) barrels. Specs are 17mm x 249mm. Dropped from 250mm for ease of printing on the P1S. You have 4 approximately 9in barrels to go from stock to muzzle for making your display/toy/replica build easier to assemble. These are very stout, 3 walls, 25% cubic infill, with a small brim during slicing. Not sure these will print on the bed slingers without support, but came our flawless on the P1S.
