Alright so this is a difficult gun to get your hands on and— similar to Tokyo Marui— its brand is part of airsoft history. It’s a western Arms m4, so it is completely compatible with all G&P gbbr parts and magazines (and a few other brands) so parts and upgrades are abundant. In this package are: -Western Arms m4 platform -Repro Daniel Defense mk18 rail -AR Pistol Minimalist stock -5 working GBBR mags (I believe one has a chip) -5 extra, leaky mags -G&P 9” barrel and extra WA outer barrel -Magpul repro foregrip Total MSRP in this build is just over $1000 but priced as is because of age and two issues: -nozzle issue: there is something off with the nozzle; it won’t direct gas into the BB but will cycle the bolt perfectly. Either fix this nozzle or buy a new one for $30 (recommend an NPAS nozzle!) -Handguard: !NO BARREL NUT! The handguard doesn’t have the barrel nut so it will need one to be attached! The gun cycles perfectly and has very little ware (can send pictures The parts to get are cheap but I’ve gotta sell to make rent now. My loss your gain I guess Message with any questions!
