Thanks everyone for the help so far sorry for the last responds I was camping. Any way when you guys say gas you mean gas impingement right? Also it's true at all mil spec part will work with each other? I want to double check just so I don't order stuff and they don't work together.
Hey guys my Dad and I are going to build Ar-15 and I was wondering the what parts are good? what parts are bad? Whether we should go gas piston or impingement etc. note: this is probably going to be a long term project.
See that's why I want the MR556A1 because I have a friend blown off by a direct impingement gun and I know gas piston systems are more reliable and less maintance
