Want to get an AK in 7.62x39 - already have a very nice stamped one made by Gunplumber in 5.45x39 I have the opportunity to buy a very lightly used Arsenal SA M7 for $1200 locally. But I have also seen the new Arsenal Saiga SGL21 rifles for $740 shipped. So, I assume the SA M7 will weigh more due to it being milled. But other than the weight, is there a huge difference in accuracy, trigger feel/pull, etc. between the two? I mean, is there really a $460 difference? Wanna kill these ads? We can help!
