Things I liked:I really liked how the hop-up adjustment bar on this unit was metal instead of plastic like on the stock unit. Things I would have changed:Nothing at all. What others should know:It's definitely worth the small price asked for it.
Things I liked:First off, these are the best bb's I've used so far. I like that they are 5.94mm +/- .01mm, meaning they are very precise, capable of being used in a tight bore barrel with little worry of them jamming. These also greatly increased the accuracy of my UTG Shadow Ops MK96 because the heavier weight of the bb means that it will be affected less by the wind while the bb is in flight. I can now make accurate shots 10/10 times at 200 feet using these bb's. Things I would have changed:make them 5.98 +/- .01mm. What others should know:Use these if your gun is upwards of 500 FPS with a .2g bb, these .36g bb's will give you the accuracy and distance you need.
