LCT CNC Aluminum Railed Rear Sight for AK Series AEG Rifles

"Solid piece; Required some filing to fit on my CYMA AK and the screws it came with are pretty crap (stripped nearly immediately when tightening) but it's cheaper than the knock-off Zenit's and adds a nice rail where your useless rear sight would be.

"Summary: Small sights/red-dots only and use Loctite.

I picked up one of these for the LCT RPK NV. It fit just fine. The way this thing works is you remove the rear sight and plop this thing down instead. An M3 bolt goes through the rear sight mount and through this rail piece. It has a nut that goes on the other end. After that's done, the rail will still be floppy and loose. There are two grub screws in the front of it that protrude down and one in the rear. You use the included small hex wrench press these out into the rifle until the rail is level and snug with no movement.

Unfortunately, the front two grub screws are only barely in front of the cross bolt. This gives them a very small moment arm to apply pressure. The rear grub screw is a lot further away so it's easy to extend that and overpower the front two. I also found that shooting an LMG all day meant these would constantly get loose and the rail would start to wiggle again. I had to tighten it every game, which also means the sight was losing zero.

I ran it with a LPVO but I really don't recommend that. It worked but there's so much weight and leverage going through a single M3 bolt, it's just a matter of time before that bolt sheers and the scope falls off in battle.

I would only recommend this for a cheap way to add a lightweight or small red dot to an AK platform. And use Loctite!

I'm going to swap to a dust-cover type rail instead for the scope, or just run a red-dot instead.
