Just as expected
Quick easy install, easy adjustments and perfect lock up on the rifle. Purchase came fast and no one else in the world seemed to have it in stock. +1 for Brownells as always. Would recommend to anyone looking to put an optic on their AK platform. This is what a lot of the pro's use and after reading a gazilions reviews, and doing tons of research, I'm glad I purchased. Would definitely purchase again. I used their plate that covers the Burris Fast Fire and it fir perfect. Alignment was easy and install in seconds.
rock-solid
This thing is light-weight, rock-solid and super-adjustable, to compensate for the AKM's lack of milspec-ness. Mounted a Vortex Diamondback 4x12 on my RAS-47 and have shot it repeatedly at 100, 200, 300m (yeah, all the armchair experts gonna hate on the RAS, but it has a great barrel and printed 7" groups at 300m). I obviously used loc-tite when I put the top rail on. Holds zero, and doesn't even lose zero when I use cantilever function to pop it off and put it back on. My friend was super impressed and bought one and is equally happy. Going to put one on my Saiga 74. They are expensive, but worth it.
Exceptional
The fit, finish and quality is exceptional. The scope mount fits very closely to the top of the dust cover and the side of the receiver As the previous review mentions, you will need to purchase the upper half, which is sold seperately. It is almost too nice to mount on my rifle. Very happy with this purchase.
Works great with my RAS47
When you open the box the quality of this rail is readily apparent. The hex screw is extremely to adjust, one or two small adjustment had the rail sliding easily on and locking positively in place. Don't forget, you need to purchase an upper to complete the system. I purchased the AKR upper for maximum flexibility for use with multiple sights.
Returns
Great product, but make sure you buy from brownells or third party sites since rsregulate has terrible customer service and return policies
