I just gotta hold it on. it covers the lens of my 589 and there's a black shade so no beam leakage happens on both. I bought it for $9 at surplus shed.
here's a pic maybe some of you have it. They don't have them in stock ):
" It has a rubber armored body that measures just over 3 ½ inches long (9cm) and about 1 inch diameter. " maybe you can find one just like it if you have a spartan you can glue gun it on with damaging the laser. Works great as a beam expander.
