"I purchased these BBs because they are used widely by the people I play with and have had good reviews. However, after using these BBs, I would not recommend them to people using Elite Force products. I recently purchased these BBs along with an Elite Force TAR 21 and had some minor feeding problems in the magazine. At that point, I assumed I had a faulty magazine, so I went ahead and ordered some Elite Force Magazines to replace the one I thought was broken. Sure enough, the new magazines still had the same issues. Some time later I simply used a different brand of BBs and the gun fed perfectly, and have ever since. I'm not sure if I just got a bad batch of BBs or they just have problems in my brand of gun, but to anyone with Elite Force, be careful when purchasing these."
