MGI has introduced their modular AR-15 weapon system. You can see some detailed pics here. You can buy it here. It’s a neat concept. The lower receiver has interchangeable magazine wells so the weapon can take either AR-15 magazines or AK-47 Magazines. It also has a quick change barrel system so that you can swap between your 5.56 and 7.62X39 barrels. It basically gives you one AR-15 that can fire multiple calibers. Interesting concept. However, I see no prices listed and I’d say for the price of that thing, you could just buy two AR-15s.
