Interesting to pick up a 10-year old thread.
The market is offering today Magwedge, Wartak and Kodiak.
Google AI claims Magwedge is the winner. I bought Magwedge. Upon running in the bushes I grabbed my SKS with one hand palm over the rail and fingers underneath the stock. This freaking rail bowed and stayed bent. I eyeballed straightening it up by bending up and down over a thumb
Upon assembly I lost a bolt in a pin. Customer service you say? Lol. $26.29 and it's yours. No more and never again. On the sidenote who could possibly call their product Kwikrail. So ###.
Oh, forgot: someone say it has a groove to see the front sight. That's what for? To shoot 10 feet in a circus range? Rear sight is removed so it's like to have a slingless slingshot.
Wartak could be fine but it's no better than Magwedge. Much stronger for sure. The same price range too. The downfall however is in the holes for the rear pin — they are too wide and without using a retaining washer this rail is useless. With wide holes and thin pin it has an up and down motion. Retaining washer is a solution but zero will eventually give up. Plus an absolutely useless idea of a 2-piece rail makes always wonder, genuinely: why?
The winner is Kodiak. Solid, sturdy, precise and flashy looking. Especially late model with white letters. Yum! Their customer service is top notch. Charged me a few bucks for a lettermail when asked to send me a spare pin (based on my previous experience with Kwik-lol-rail).
Something like this. In response to Magwedge revving about their nearly 1000 sales a decade ago

Their quality may apply to an airsoft market, an air pump plinker but definitely not to an SKS.
