Finally had the opportunity to try the PWS upper out at the range, all I can say is WOW! My daughter and I had a blast, literally. I was very pleased with the accuracy of such a short barrel, after initial sight-in we were taking head shots on silhouette targets at 50 meters. Afterwards I stripped it down for cleaning and inspection. Everything cleaned up very nicely and there were no problems found. I look forward to many more range days like today.
