Barrel Band in 2 pieces for Diana Stormrider/Artemis/SPK

thingiverse

The Artemis/Snowpeak/SPA PR900W is the Diana Stormrider of Chinese manufacture. Lots of people say that the barrel needs another band nearer the muzzle to stabilize the rifle and improve groups. My Artemis has the front sight press-fit on the barrel, and is difficult to remove which makes adding a one-piece barrel band impossible unless you dismantle the rifle by removing the barrel completely. My solution is to have a two-piece band that can be installed without having to do any disassembly. The parts can be printed on their sides, with supports because of the internal holes. Some light filing might be needed along the top and bottom to make a slight chamfer, but I found that to be unnecessary as the parts gripped the barrel and air tube with sufficient force that nothing will move. A m3x20mm socket cap screw and nyloc bolt hold it together.
