The only accurate one is BLADE RUNNER BLASTER TOMENOSUKE HCG EXCLUSIVE EDITION 1/150. There is one on Ebay for $1,080.00 which is a great price. There is another but it is way overpriced.
This one is the only one with an accurate finish having the barrel blued. It is built to be an AFB version and then you leave it or mod it to look like his blaster during production.
The real blaster today looks nothing like it did for filming. I have pics of it from before filming began and you can google it of course.
So if you want to start off with it finished right that's the one.
The other great one was the very first one which came with a similar nice blue finish but not as good as the HCG exclusive and it had the wrong color grips commonly called the "rootbeer" grips. You will also find them on later models as guys bought later models, switched the grips and re-sold them to unsuspecting people.
The rest of the models,,,,,, Let me just say all the models are awesome and all pretty much the same except for the finish. There are minute details they brag about fixing but I owned the first and a later model and could not see any difference. Now I have just the HCG and it's perfect. The later models have inaccurate gun metal finishes including the 2049 and even the more expensive latest version, the "2019" is not nearly as accurate as the HGC.
Okay no hate, just my opinion so nobody get made.
