I bet I could get it running.i would never buy bear creek anything but ar platform is so simple I'm sure I could get it running.at worst you trade a couple parts around
But definitely give up in the cheap odd ball stuff.but again I get I could get it running but I've never fooled with bottom barrel stuff other than my bro in law buying bear creek 450 bushmaster and his required rifle buffer and tube to get running but again that was him not me
