Alexander and Franklin ARs

[res308]

Friend of mine sent me a list of some guns he’s selling. He knows I’m looking for an AR. He has an Alexander arms Incursion rifle in 5.56 and a Franklin Armory A.R. 15 (I don’t know which model yet).

I don’t know anything much about these two brands. Trying to research them is irritating. When I try to find Franklin Armory AR15 reviews, all I find is talk about the binary trigger, which I care nothing about. Same with the Alexander Arms, all I find is talk of the 6.5 Grendel. 
Does anyone know anything about the quality of these two brands and the materials used, especially in the bolt and the barrel?
