MOD: KWA Hopup with Prometheus barrels
Posted: 2014-02-23 / 07:37 UTC GMT +00:00Do KWA m4 hopup units (from a gun made in 2012-2013) accept Prometheus barrels? I'm having hopup issues and I'm thinking the OD of the barrel is too big. It took me a while to get the barrel and bucking into the unit because it felt very tight (yes that's what she said 
).
