"I was first off very impressed with the very robust and durable build, despite the cheap plastic construction. A very strong and surprisingly accurate (considering the size and rudimentary build) but the sights are absolutely horrid! they are not only inaccurate, but but not able to even be used, as the rail system blocks them! other than that, troubles with the magazine are common, its not a broken parts issue as much as it is just a problem loading the magazine, it requires patience and delicate handiwork, even with a speed loader. good strength and good velocity overall trump over the mag and sights issue. great for CQB battles, not so much for field work, though."
