Aluminum construction, matte black finish, 3" long. Ares ETR available in black or FDE.
Had ordered a sunshade from a different supplier and the fit was loose and would not tighten up properly. I reached out to A&J and they immediately got back to me and assured me that this one would work and offered to return it free of charge if it didn't fit. I placed and order from them and it shipped extremely fast and fits perfectly on my Cronos BTR Gen2, don't hesitate to order!
These are not easy to find for the Cronus so A+ to A&J SG.
