I can't speak highly enough for the AK--there are so many myths and half-truths going around, probably due to quality variance and use and abuse. I've had 2 Saiga SGL10s modded by Chris Butler, and both consistently held 1.25" at 50yd with a Micro Aimpoint mounted on an Ultimak rail. In practice, for me the AK is a very efficient and confidence inspiring weapon for which adaptation comes quickly. Those with a tri folder, and a fixed plastic non-NATO stock.
OTOH with two months time off, I find myself having to initially search for a proper cheek weld. The AKs iron sights and the Micro Aimpoint/Ultimak set up, requires a tighter cheek weld compared to the AR. The AK with a forward mounted Aimpoint/Ultimak is definitely front heavy compared to an AR, but you get used to it. Same with the Ultimak--the forward mount becomes sweet with practice, and it opens up peripheral vision.
If it wasn't for my time and history with the AR, I would have adopted the AK. I have huge love for the AKs caliber, handling, and recoil impulse. No problem with fast doubles.
