Vortex killflash ard - Vortex killFLASH ARD for SPARC Red Dot Threaded

This thing is pretty cool & does what it is meant to do. The only down fall I see is that it is plastic. Might not be an issue if it were a snap on, but due to the very very fine threads on the ARD & the aluminum threads on the SPARC it could be quite possible to cross thread if your not careful.
Pros: Prevents reflective lens glare
Cons: Plastic
