I bought this for a KS-1 project. I have used the real KS-1 and can confirm that aesthetically, this is almost identical. That should be enough to tell you it's a good can. The ratchets are tight, the paint is clean and the trades are clear. The fact it came with the bespoke flash-hider means that you could attach it to any regular thread (I believe 14mm -ve). This was also the best price I could find it at, even taking into account postage and possible customs charges to the UK.

I just love it.
The color is good, and it's easy to fit.
