I have both brands. I can say that the quality of the guns to me seems very equal when comparing. Finish on both are great, anf fit on all are equal as well.
The one area where Jimmy at Global Trades COULD DO A BETTER JOB....is to communicate better.
My Arsenal USA models are the SSR-85B, SSR-85C, and SS$-74/S - all built on Hungarian Feg receivers. I also have 3 other Armory USA receivers....which have been built...and are perfect as well. We have built 2 Polish Tantals, and a Yugo M92 Krinkov with these receivers.
My Arsenal model is a SLR-105A1 model.
You cannot go wrong with either
