The are better and worse guns than a Remington R25. large frame AR pattern rifles are signicantly heavier than their AR15 counter parts. Whether that extra weight will be good or bad depends on how you will use the rifle. The way I [hunt/shoot] the weight of a large frame AR would not be a hinderance. Your milage may varry. If you decide you still want a large frame AR pattern rifle, there is nothing wrong with a Remington R25. Its a DPMS rifle with Remingtons name on it. As stated in an Earlier post, if you buy a DPMS labled rifle (as apposed to a Remington labled rifle) you will have more options from which to pick. If it were my money to spend I would do directly to DPMS. If you decide to buy A Remington lable rifle, IMEDIATLY REMOVE THE STOCK TRIGGER AND REPLACE IT. A Giesle ALG tigger is an exilent field trigger for a hunting rifle. it breaks clean and consistant and the pull is about 3 pounds lighter than a DPMS trigger. Its not a match trigger like the premium Giesle triggers but a good quality trigger.
