First off, I have worked in a gun shop and built or refinished quite a few firearms. I am by no means a pro but an apprentice to the trade, I feel anyways. I have built a few Ar's for myself and I have generally used Sabre lowers as I got them for $110 out the door. I have used various uppers and lower parts kits but I found a deal I think. I did an impulse buy I know bad idea but it was on sale. I walked out the door of a local gun shop with a new carry handle 16" base model DPMS carbine for $679 with two boxes of wolf ammo (40rds.). Now, I love carry handle models just my choice but to me that's cheaper than building ( DPMS I bought) but give me the honest truth. Now before anyone says anything about flattops, I've had an M&P flattop with carry handle screwed on and I hated it I love true carry handle with a Trijicon mounted for fast fire.
