Model 4 rifle kit

Right now, I can only comment on appearance, but it looks great. Fit and finish is top notch, and all the little extras that come in the kit are nice. It is a little on the heavy side. That isn't a complaint, just an observation. It is a bit front heavy, but that is to be expected from a 20 inch barrel. I have been looking for an m16 clone kit for a long time, and I'm glad I found this one. This is amazing value for price, and I can't wait until I am able to complete this build.
