I've posted on this forum that I needed this AEA gun as quiet as possible. I've heard it has issues NOT cycling in semi-auto with an aftermarket moderator. Does it or NOT ? Guys that have responded to my posts about this brand of semi-auto havent mentioned issues with their guns that do have DFL mods on them. A couple of guys have but have been a little unclear about what they did other than removing these mods from their guns.
