This is my first WWII airsoft gun that I have purchased and it is at the head of a WWII collection I will be putting together and allow me to say that this weapon is AMAZING. Unfortunately I don't have any way of measuring FPS however the test record that was provided by AirsoftGI claimed that it measured around 330 fps which sounds and feels about right. This gun is an amazingly sturdy built gun, not only is it an amazing Sten replica but is also very functional and feels great as a CQB and close-field weapon. Two mags would have been nice seeing that its current mag does not hold much, but I have enough speed loaders to compensate for now, although I plan on purchasing a few more mags for it. My one complaint is the loose mag receiver, the piece moves slightly by a few millimeters only, so it's not a big deal. I found this gun to be a GREAT gun and cannot wait to continue to my next purchase!
-Sturdy build, very few parts wobbled and the ones that did only did slightly.
-High ROF, although I cannot "officially" test the ROF I can say that it is quite fast.
-Mid cap magazine, the magazine is a mid-cap of which I love as it feeds well and does not require winding.
-Short, mobile design.
-It's a WWII Sten!!!
-Could have used two magazines considering the one magazine only holds about 50 rounds and getting more is quite the pain at times.
-Like I said earlier, a few wobbly parts, but not too much.
-NO SAFETY: Okay so I purchased this knowing that it has no safety although I accedently pulled the trigger while the battery was in and a bullet shot my wall and lucky hit something before coming right at me, note that I did not have a magazine in and I know am more careful. The no safety is not a problem as long as you are careful, however this weapon is NOT FOR THE RECKLESS
