"Once you manage to get this kit working, it is seriously cool and really adds the pleasing heft and solidity of steel. It consistently gets grins when people pick the gun up! That being said, it's not a task for the unfamiliar or unskilled. All components except for the grip will need some fitting. Although not depicted in the picture, a new grip and steel outer barrel are included as well. The upper receiver would not mate with the frame initially. In order for it to drop in to the point where the retaining holes align, the lower corners at the front must be radiused to match the corner radii in the inner channel of the frame. Only a very small amount of material need be filed away. The take down pin that joins the receivers may need to be reduced in diameter a few thousandths as well for an easy fit, but not the outer barrel retaining pin. Perhaps the most critical thing to know is that the thin steel inner slide housing must be removed from the original upper and inserted in the new one, or it won't fire. The retaining pin cut on the new outer barrel was mis-located. You could either make a new cut or file the existing one wider to clear the pin. Do this carefully, and your outer barrel will retain nicely and with less play than the original. The barrel pin hole on one side of the upper receiver needed to be de-burred a little as well. The inner barrel must reciprocate during firing, and both outer barrels dragged too much to allow this to occur when installed in the new receiver. Once the inside diameter of the new outer barrel was opened to .328" with a drill in a lathe, that problem was solved. The retractable stock assembly in the kit is rather more pleasing than the original, and the shoulder stock locks in it's positions much more tightly. But the shoulder stock would not lock in it's folded position when the stock assembly was retracted at first, and had to have the angle of the bend opened a little. Remove the shoulder stock to do this. Unfortunately, the weld on the locking pin for the shoulder stock broke through in short order. I opted to repair this by drilling and tapping the pin hole for a modified 8-40 screw. The screw modification was another lathe job, but the pin could have easily been soldered or re-welded. The single greatest shortcoming of this product was a complete lack of instructions. None seem to be available anywhere. That really would have saved the time lost in trial and error. I was quite pleased with the final results, and build quality of the parts was generally solid. But the lack of refinement in the design and need to do significant labor in fitting and repair was frustrating.
