Hey all, I'm looking to build a durable long lasting DMR. I am building it around a krieger 20" heavy fluted 1:11.25 twist barrel. I am interested in aero precision but then I started looking into armalite. Their supersass A10A series caught my eye as it was almost what I am trying to build but I am set on my barrel choice. My question is about the receiver sets. both companies make good recievers but what are the pros and cons of each compared to eachother? Looking for some experience to help me decide which direction to go.
