Some shooters out there want very fine adjustments which is why we are now offering this .23g bb. There are so many variants out there of Airsoft guns. Our .20g might be too light making it hard to control hop-up and our .25g bb is just a bit too heavy for the fine tuning you're looking for. Try the .23g to get right in the middle.
The .23g is generally good in guns shooting between 300 and 360fps but then again, it's all up to you.
Each 5000 rounds come in UV-resistant re-closable bags. This gives them a longer shelf life along with the convenience of a re-closable bag so your bbs end up where you want them instead of on the floor.
