Your first gun is a DMPS AR15?!? That's awesome!!! My AR15 is a Buschmaster. Everybody has their preference and opinion when it comes to gun manufactures. My opinion is that Buschmaster is a very good gun and so is a DMPS. My Bushy was just the gun that was there at the right place and time. Again congrats on that DMPS! You will have a lot of fun with it!!!
