Anyone know the explanation of how it works? I went to the CMMG website and didn't see even a sales pitch describing the function? Just curious as I have a 45 ACP Glock magazine upper ordered. Usually they describe the ins and outs or refer you to a magazine article or You Tube. Thanks and Be Well, RZ.
