Last time I tried to order from Aero they would not ship flash hiders to MD at all.Shee-it! For years they wouldn't ship certain gun parts to Md that were legal to do so after 2013. Balls? Nice to know they've finally descended.
I've grown to respect PSA a good deal after seeing some factory tours and have heard that their quality has increased a good deal. And I like that they focus on the civilian market.
