This is a lightly used (1000-1500 rounds) VFC MP5 AEG. This is pre-Avalon so this MP5 has a three round burst feature. The MP5 does shoot consistently at 390fps with 0.20g. Despite the light usage, the gearbox has been serviced - shimmed and re-greased. Part of one receiver tab snapped off but does not affect assembly or function. That portion is also covered up by the stock and therefore not visible. A custom threaded 6061 aluminum barrel adapter is installed so that any aftermarket 14mm neg attachments can be threaded on. The pre-Avalon MP5’s originally came with orange plastic adapters that easily snap. You will not need to worry about that with this metal adapter. The MP5 includes 200rd metal hi-cap mag, G&P handguard with built-in light, picatinny mount, and 11.1v stick battery. DOES NOT INCLUDE OPTIC AND SLING.
