When I first got into shooting and building AR's, a few things were different. Ammo was cheap enough I could fire 1000 to 2000 rounds a weekend, and I was single. Married now, with a stepdaughter, son-in-law, and a granddaughter living under my roof. I can't afford to play with my guns but once in a blue moon (maybe 100 rounds annually) now, so I am not putting my guns through as much as I use to. A firearm that wasn't tough enough for me back then would probably be ok for me now. DPMS might be good enough for the casual shooter. I just recommend a better built gun for someone who is going to be putting buttloads of rounds downrange like I use to. The range I go to allows machine gun and .50 cal fire, so bumpfiring isn't an issue. They can sell more targets that way.
