Went down to Engage today and started the process on my first NFA item, a 10.5" AR. Now to build the upper. I am cannibalizing a Stag Model 3 upper so I only need to get the barrel and quad rail. A buddy has a 9" DD carbine length quad rail I might buy. I am looking at getting a Rainier Arms barrel. Does anyone have any experience with them? I have also heard a heavier buffer spring is in order to increase reliability. Thanks in advance gents!
