*Please don't waste my time. Will entertain serious inquiries only. A lot of time, money and sweat was put into this build. This may look basic from the outside because its not one of those “3D printed kit” builds, but this build slaps. This is a complete build. No upgrading required. Built for longevity and semi or full auto fun. Shoots spot on. Sight already zeroed in. Has absolutely ZERO issues. Most likely the best airsoft gun I’ve owned and worked on. Never fielded only used at home and not so often. Selling as I am working on another gun build. *tracer and the small rear pictanny sight not included. (If you really really want the small pictanny sight included I may let it go but if if you don't care for it I would like to keep it as I may use it on something else) Upgrades and spare parts: Cowcow steel hammer set Cowcow steel trigger bar(filed and modified to move buttery smoothly, no sticking) Cowcow steel fire lock pin Cowcow adjustable trigger type A Cowcow aluminum nozzle block CTM steel fire selector sear TTI charge handle with full auto switch(bolt currently installed is the aap01c bolt so switch is not installed or needed unless you switch bolts) TTI aluminum magwell Narcos Aluminum Front end barrel CTM red aluminum barrel sleeve Aluminum Ghost front sight Action Army AAP-01 folding stock UTG riser RMR mount Vector Optics frenzy red dot sight Guarder lightweight extended magazine x 3 Guarder lightweight magazines x 2 TTI and slr functional magazine extension base pads x 5 Action Army cnc aluminum red extended mag release Action Army rotary hop up unit C&c 140% recoil spring 200% nozzle return spring We tech g series hammer spring(stronger then stock aap01 hammer spring) Olight baldr laser light combo Many spare parts back up parts are included.
