Well, it's a barrel extension. In my opinion, this should be included with the WE SCAR or WE should have released two models as they did with the PDW, but I guess they get more money this way.
I bought this one instead of the more expensive RATech kit because I hoped that the finish would exactly match the outer barrel of my WE SCAR since they're made by the same company, but I was wrong. This barrel extension has a more flat sheen than the stock one, but it isn't noticeable at all unless you remove the barrel assembly and really look at it.
For all you trademark junkies out there, this barrel extension has a Belgian proof mark stamped into it, which was a nice touch by WE.
The barrel that it comes with is just a brass barrel, not much to write home about
My SCAR no longer looks stunted.
Nice looking Belgian proof mark.
Finish doesn't quite match.
