Barrel shroud for the BK1S. Didn't want a bunch of added weight, but something I could grasp and didn't look milsim for club rules.

Around the factory ring - it'll fit VERY tightly, you'll likely have to sand/file as needed to get around the nut portion. Just enough barrel showing for a SCAR/BCAR at the tip. 

Probably very fragile in PLA, but in a PETG printed with 4-5 walls - flexes but does exactly as intended, provides a place to grab other than the barrel.
