Just bought my lower and within the next week or so will be buying my LPK. I'm looking and researching uppers that I want and am not dead set on one yet. I'm probably going to get a PSA upper to keep everything PSA and Magpul. While researching, I came across a company called DS Arms. I have not hears of them, but they have dirt cheap uppers. For example, they have a 14.5" M4 profile complete upper (sans BCG) for $150. Anyone out there able to vouch for them? If I can get enough people who have good things to say, I might just buy one to test it. Please don't bash it due to the price, I want real world experiences here.
