There is a new lower receiver for Kalifornia AR shooters. The FAB 10. Basically this is a standard AR rcvr without a removable magazine. The rcvr has a 10 round box magazine incorporated that is loaded via a stripper clip.
Only problem is that the upper rcvr must be "broken open" by removal of rear rcvr pin so that the rifle can be "opened" to allow inserting cartridges into the box mag.
The standard AR ejecion port is very small and doesn't really allow you to get your fingers in. Does any one know if the upper rcvr ejection port could be "opened up" to allow loading into the box mag kind of like you would do on a bolt action rifle? If the ejection port could be enlarged you could load 10 rounds into your box mag "one-at-time" without breaking open the rifle.
What do your think???
