Stag Model 4 Rifle Kit

Complete kit minus the lower receiver. Assembled quickly and fit my stripped lower perfectly. Functions great and accuracy is as good as can be expected with iron sights and me at the trigger. Excellent A2 build. Very pleased. Strongly recommend!

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.
