One issue with kit so far that I figured would write up in case someone else builds it.
The part that goes around the main gun, the skirt so to say had only two little tiny pins that aligns into holes on the lower part. The top part is springy and wider so it shears those pins right off. Fixed that using the rubber bands and super glue. The creases or ridges in the skirt are horrible as far as matching goas. I will fix that with a three sided small file to match up.
