Double Your Fun
With some things in life more is generally better. One of these things is ammunition capacity, the more rounds you can hold the more fun you can have and California Competition Works is here to help with their PMAG coupler. Basically it's a small device that allows you to take two PMAGs and couple them together to create a larger magazine thus you can get a 60-round magazine by coupling two 30-round PMAGs together.
A hat tip goes to Every Day, No Days Off for bringing this product to my attention.
