Crosman seal for 12 gram changer, new, 1 included.
These seals fit the following paintball markers:
Brass Eagle Nightmares (early Brass version and Aluminum Versions)
Some nelson 12 gram drop out changers such as the drop out made by Aerostar and those made by WGP that fit commandos and rangers. They also fit Nelson based California Cobras
Some Carter Rat Attack Changers
ASA 12 gram changers made by WGP whose body Twists to release the 12 gram.
I have been told these will also fit Piranha USP pistols' 12 gram changer.
