i bought this for my CM MP5 and they work great!
they are heavy witch really helps for those long range shots that are allways blown aroung in the wind, not to mention, better for the enviroment. also, they biodegrade slowly so if it is humid out they will not biodegrade in your gun, causing them to jam and break your gun, all around, some of the best BBs i have ever used
-biodegradable (but slowly)
-very acurate precision(about 5.96 diameter)
-smooth, no imperfections
-good value for bio's ($5 for 1000 or 1/2 cent per BB)
-if there was even one missfire i would write it but i haven't had a sigle one yet in the 2 bags i have gone through!
