Things I liked:Heavy duty feeling, acceptable FPS, decent accuracy, and ease of upgrading. Things I would have changed:Include the upgraded spring. What others should know:This rifle rocks! My son hit me from over 150FT and the BB still had enough zing to create a nice welt!
Things I liked:This gun is fun as heck to shoot!!! Things I would have changed:Things I would change: add an expansion chamber and more die cast parts rather than plastic! What others should know:The action on this gun freezes during mild temperatures making the gun shoot at lower FPS. So, after several repetitive "bursts" give it time to thaw out....don't yank on the charging handle if it doesn't move...it's frozen because of the CO2.
