BudsGunShop.com - Round Count

Hi Matthew, first thing, the link in James' answer below is a S C A M website, do not buy form there, you will lose your money.
The 5rd model is no longer in production. This 7rd model comes with a plug installed to reduce the magazine capacity to 2 rounds. The plug is a wooden dowel that you can cut to length if you want to reduce the capacity to 5 rounds.
Stay safe & have a great day!
