They are absolute shit lol.
I have had loads of AG parts, all but one of them have problems..they clearly test nothing! There is no other explanation for it.
Ag nozzle, weird full auto so removed.
Ag bolt (sf version) piston wouldn't fit, also spring retainer wouldn't go in without modding.
Ag outer barrel, hop issues when installed
Ag maritime bolt catch, sticks out about 3mm more than a real one, so you cannot wind the mag release enough to seat it properly. They even admitted to me they screwed it up!
Ag mag release, fell in half first use lol..pin just fell out!
Ag charging handle, roll pins just fall out
Ag lightweight bolt catch, needed heavy filing to move freely.
Ag urgi v2 rail, will not fit an mws without their adapter ring which only comes with their outer barrel set which causes hop problems! The v1 rail was fine and had a more durable finish.
Saying that, my flash hider is perfectly fine, even they would struggle to fuck that up.
They clearly make things based on pictures on the Internet, this is why everything is out of spec..then they clearly do not test finished products on a base mws but on modified ones made from their parts.
I hope they go out of business.
