These are very good high quality bbs. Made by Madbull but then stamped with the GI brand, these bbs are good to go for all airsoft guns(I use them in my pistol and AEG). I've used about 10 bags of these in my KWA M4 and all 3 of my pistols and have had only had two jams (one was the magazines fault). BUY!!!
12,000 bbs for 36 bucks= great deal
more bang for your buck
goes through brush quite well
more kinetic energy than .2s (meaning at a distance, it will be more noticeable when you get hit by them)
Final Statement- Buy you wont regret!
