I can recommend the Arsenal, Inc. SA-M7S. Probably the best made-in-the-US AK yuo can buy. In fact, I'd venture that it's the best AK, period. I base this on a 2 main factors:
1) Arsenal's are based on the Bulgarian AK's, which utilize milled receivers, as opposed to stamped. Beyond appearance, this difference is otherwise indiscernable to the end user. But, milled receivers are stronger & a little heavier (better recoil dampening).
Roughly $750.00 - a little more than the $300.00 Ak's out there, but definitely worth it, IMO.
2) Arsenal is licensed by the actual AK firm in Bugaria to mfg. their AK's, & even uses some of the original set & tolerance guages from said factory in the mfg. process.
