The first i heard of these BBs was when i was in germany at the IWA and speaking to the guys who are making them. the guy took a few of them out of the bottle and handed them to me, then proceeded to give us all the patter etc about how they dont rub, chip, smudge, do any damage, they dont shatter etc etc. yet while he was waffling on, i was rubbing it in my hand and it started transferring really easy. then i put some very light pressure on it with my nail and the coating just chipped away.
To anyone even considering getting these BBs, I would highly discourage using them at all. they will ruin your barrel and hopup. the colouring will come off as it passes through the hopup, then the air nozzle is going to push it down into the hop chamber resulting in more colouring left in the hopup and air nozzle. then its going to go down the barrel which will in turn, effect your accuracy and could lead to jams. If your gun is still under warrenty too, it would be worth checking with the retailer before using these as its not going to be hard to tell if you end up needing a repair.
The BB itself isnt actually smooth so im not holding out much hope for how accurate it will be. that coupled with the fact that its already scratched before it fires will effect its flight. Also, to put into context these people making them, they were trying to sell us some really low end cheapo springer guns and were singing the praises like as if they were made from gold. When we laughed that off and asked if there was any proper airsoft gear, they replied with, "yes, we do the Classic Army range".
These BBs are nothing more than glorified paintball BBs from the poundshop.
Sooo ehh. No.
