AAC-21 (Gas M700)
 

Hey guys,

Been looking at grabbing one of these for abit and just wondering if anyone has first hand info on them. I cannot find if any internal upgrades are done to these other that having a longer inner barrel. Shoots 450-480 on green gas which is pretty amazing and have seen reviews saying FPS is consistent.

The next part of this would be suggestions other than a PDI barrel and ER hop that is needed. I have built and have had built many spring bolt action rifles over the years but this is my first look at a gas rifle and something not a TM vsr10 or APS2 (no Azathoth I will not sell them for 100$ and a snickers bar).

Thanks in Advance!

IIRC it's based on a KJW M700 if that helps.

Yea I saw it was based on the KJW and it has a body kit for the KJW and the Tanaka but it was made totally by Action Army but they don't say if its the old KJW hop up and barrel and valves or if they are the upgraded action Army ones... Because the old KJW were not producing 480fps.
