I'm relatively new to ARs and just received a Stag 3H upper from Stag (http://www.stagarms.com/product_info.php?cPath=14_24&products_id=244), which I am mating to a RRA lower. I am planning to put a red dot or scope on it, with BUIS just in case. But honestly I doubt I'll use the BUIS much. I have two questions about the upper:
1) The gas block is a little canted compared to the top rail, which is perfectly level horizontally. (I checked this with levels on a flat surface.) I'm wondering how this will affect my ability to get the BUIS to shoot straight, and how concerned I should be. I would've thought this gets checked before shipping, but maybe not.
2) There is a little play between the upper and lower. Is this normal, or should it be a very tight fit.
I'm reluctant to send it back if I don't have to, because you never know what will be wrong the next time. I like that the top rail, which is what I'll be using the most, is centered horizontally.
By the same token, I paid my money and don't want to accept something if it considered "defective."
Can you answer my questions and offer any advice. Thanks.
