PLEASE BE SAFE IF YOU ORDER THIS AND DO NOT USE FOR PUBLIC PLAY! I ordered a custom black sleeve for the MKIV for use in a realistic private LARP on a private closed game site. This product did not disappoint! It looks great, fits perfectly and the print quality is amazing. Now I can use the standard orange muzzle sleeve for transport to the game site or on blasters I will use for public play and when I get to the private site I play on I can switch the sleeve to the black muzzle sleeve. This vendor was very responsive to my request and worked with me to get exactly what I wanted. The turn around time from order to my door was excellent. I will definitely be ordering from this vendor again.
