A&K isn't low-end. They make very good quality airsoft electric rifles. Their Masada ACW-R is one of the highest bought AEG's on the market.
Not so much Low-End but they make cheaper guns with some less quality parts. Good example, Masada it's a great gun for the price but A&K made it so people
wouldn't have to spend 500 dollars on the Magpul Version. A&K is a great company if your not looking to break your budget, I personally own there M6O, and
for 300 dollars you cant beat it.
