Local buyers preferred, located in Southern California Externals: -H&R US MADE GI QUALITY CARBINE LENGTH DROP IN 6 HOLE HANDGUARD (awful original handguard from Boomarms included, no idea why you might want it but I'll include it) -Guns Modify one piece buffer tube included but not installed -Weaver optic mount Internals: -Bavtac Nozzle spring, Federal Concepts NPAs, stock otherwise Extras: -Dytac nozzle spring, GM nozzle, choice of OEM, HAO, or Bavtac ZET plate **MWS Stuff: Mostly free with purchase, $60 for OEM MWS trigger box** This M733 was prebuilt by Boomarms, and has amazing finish and trademarks. https://boomarms.com/nl/products/boomarms-custom-m733-mws-airsoft-gbb I've fielded it both outdoors and indoors (hence the superficial scratches) and it performs amazingly. I bought the Guns Modify one piece buffer tube if the OEM buffer tube breaks, but I was just too lazy to install it so I'll be including it in the purchase. With the new handguard, it feels light but solid in the hands, thanks to the flash hider, front sight post, handguard cap, and outer barrel all being steel. And because I'm moving on from the MWS system, I will be offloading all of my MWS spare parts as well. I think the only thing I will charge for would be the OEM trigger box, but otherwise everything will be free. Parts include: -GM nozzles -Dytac and Bavtac nozzle springs -ZET plates (OEM, HAO, Bavtac) -Guns modify hop up adjuster set -Guns modify CNC steel dust cover -Guns modify bolt carrier -Dynamic precision valve blocker -Wii tech CNC hop up chamber -Magazine o-ring repair kit -G&P steel buffer lock set -Magazine and bolt release -Many magazine router and feed lips -Angry gun heavy buffer that's giga heavy -Buffer tube shims -Barrel nut shims Please let me know if you have any more questions, the only thing is I will not be looking to trade.
