Hey guys I have my western arms gbb m4 for either trade or sale, it has an aftermarket outer barrel, ncstar rail system, PTS battle comp, RA-TECH trigger assembly, G&P trigger springs, prowin barrel guide/ hop up adjustment, reaps a+ bucking, and trigger mod done to reduce pull, this is an expensive build, invested about $600 in it total. So I'm looking for around $300 will haggle on prices but not very much so please don't come to me with an insulting offer, or trade for mk18, VFC 416, sr25 or dmr m4, I may be a little picky on trades because Customer builds are kind of going slow at the shop Right now so im looking to do 1 of 2 builds depending on your gun your willing to trade, so please don't be offended If I don't agree, text me at 480-620-0380 thanks guys
