Merlin- BM and ARM are waaaay overpriced! Any company that asks retail of $915 (BM) and $1004 (ARM) for an AR15 is crazy! (even if you can find them cheaper, I don't have near that money).
If you use quality companies and parts you can build a very nice rifle for $600-700. JT Distributing is reputable, and reasonably priced. I used an Oly barrel, with FN upper, FN bolt and a RRA lower. Rifle cost me $600. (never burped once, except for mag problems).
Then I got cheap and bought A M1S carry handle. Rifle was shooting 12" high at 25 yards!!!! That is 4 feet at 100yards! I call them up to send it back, and the secretary argues with me for 15 minutes that Gunsmoke sells DPMS uppers, and DPMS are .003 lower than other A3s. I called Ed and he said that that was total BS. (she also argued about the ship date, which I verified I was right with UPS) To boot, she didn't know what an aperture is!
ME: "Ma'am I ordered the carry handle with the A2 aperture"
HER: "Well we sent you the A2 aperture, it just had National Match sights"
THE APERTURE MAKES IT A2 or NM!!!
They are a bunch of morons who make shit for products and I will never deal with them again.
