Product details

Plastic BB stoppers are damaged more quickly because GBB nozzles are thicker and can eventually leave damage, causing the BB to roll back into the receiver, and you can no longer load the weapon. Our Steel BB stopper ensures that your weapon loads normally again and the BBs do not go back into your receiver.

Our stopper is made of extremely strong stainless steel and comes with a light spring that also makes it more desirable to load your weapon.
