Good Morning, Over the last few years I have accquired an interest in owning a AR type rifle in .223 Remington for varmint hunting and need some opinions and direction on buying one. I have a friend...who has a friend with a DPMS Bull 20 rifle in 223 Remington that is for sale. What I would like to know is....How does DPMS compare to all of the other AR manufactured rifles on the market today? My use interest for the rifle would be for varmint shooting....woodchucks and maybe coyotes. This also fits into my budget as far as buying it, plus all of the reloading components to feed it. Thanks, Richard Ramsey
