Bear with me I am new at this. A friend and I are getting AMD 65 parts kits no receiver of course and no barrel my question is on the barrel if I get a 16 + inch US made barrel do I have to get a longer gas tube? Or is that issue only with those that want to put on a top hand guard ?
So if the gas tube is shorter and you are putting on a standard length barrel does that mean that you have to put on a longer gas tube and a different gas piston on the bolt?
If that is the case is it easier to buy a barrel that you need to drill the gas hole in the barrel to use the original parts? Or am I making this all harder then it is?
