You must be damn proud of your son, I know I would be. My dad was custom rifle builder and I grew up watching him rifle barrels, float stocks, etc. Then we would hit the range every weekend and put 1/2" groups of five at 500 yds. We were both competition bench rest shooters for many years...truly a great hobby.
As for the Cycra
plastics, I have to say that I'm not impressed...AT ALL. The rear fender literally broke from back tire roost. I hadn't fell over or been run into and I look over after a moto session and the very back tip of the vendor is missing a 3" chunk. The front fender is very flimsy and likes to wiggle a lot. Yes, I wont' buy them again unless they make some significant changes to their stuff.
