The proper airsoft BB can make or break your game. The BBs we carry here at MiR Tactical have been proven to shoot straight with the best accuracy. All of our high-quality BBs are smooth, polished, and consistent in size. For beginner series airsoft rifles, such as G&G raiders, choose either 0.20g -0.25g BBs. For higher end airsoft guns such as Elite Force VFC Avalons, choose 0.28 -0.32g BBs, and for sniper rifles and HPA guns, choose 0.36-0.40g BBs.
