Re: DPMS AR-15 Accuaracy/Dependability
AR dependability depends far more on ammo quality than most anything else. DPMS has made some pretty decent stuff, and they're still used by an awful lot of Service Rifle competitors. Mil Spec is the gold standard when dealing with service rifles, so just check their status via their catalog, website or whatever. If they're making Mil Spec stuff, they'll say so.
What exactly are you doing with this? Little more info might be helpful here.
