I am new to the AR game and am thinking about buying an AR to add to my collection. A friend offered to trade me a stripped lower as a starting point and I am wondering how much money I should expect to spend on building an AR 15 from a lower this way. I suspect there isn't really a cost savings in building over buying a complete gun but it does appeal to me in that I can spread the cost out over time and build something exactly as I would like it without having to find something similar and modify to suit. What kind of ball park figures have you guys spent on building AR's? I am not necessarily looking for the highest end parts I am on a tight budget but I want to have a quality firearm with decent resale value if I end up wanting to sell it. please share your thoughts and experiences
