Well I'm no expert........while some folks add the wire from the Hengstler counter to the power cylinders, I don't think any of the movie props actually had them. The grip/handle is super chunky and there's too many vent holes. I'm pretty sure the scope and counter are in the wrong position,
They sell their Sterling Machine Gun base for about $280, so I'm guessing it will be a tad more expensive than that.
While this is the Sterling Machine Gun it makes sense to have the folding stock, kind of redundant on an e11 as they were never used like that.
The scope seems to be upside down and the seam on top is distracting, the t-tracks are too short and they missed some holes, and the wires look bad. The Hengstler counter is way too backwards and doesn't look too good either, at least the back part. It has the same fat grips and long endcap like all airsoft Sterlings so far. Not impressed.
