MG Industries (MGI) manufactures a modular rifle system that takes the basics of an AR platform and allows you to swap calibers quicker than many people change underwear.  Too cliched?  Perhaps, but true nonetheless.  Let’s face it some folks change underwear a little slow and not frequently enough.
MGI is now making a rifle and a caliber conversion for the .308 Winchester cartridge.  The rifle will have an 18″ quick change barrel with a 1:10 twist.  Total weight is less than eight pounds.
MSRP is $1795, while the conversion kit is $750.
If you have never seen how quickly the MGI rifles can be converted to different calibers, watch the video below.  In the video, you’ll see the barrel, magwell and bolt assembly changed from 5.56 to 7.62×39 in about 90 seconds.  The newly converted rifle will now be set up to fire the new cartridge, including using AK mags.  It is an amazingly easy swap.
We’ll bring you photos and more information on the MGI .308 modular rifle from the 2012 SHOT Show next week.
MG Industries also offers a variety of other interesting rifles, including a belt-fed AR-15 style rifle.  The company also makes versions of the gun, and conversions for the gun, to other calibers such as 9mm, .40 S&W, .45 ACP, .450 Thumper, .22 LR and more.  These rifles are pretty amazing guns and I have seen them swapped in person.  The conversions are quick and easy.  It is just a simple system that works.
I have not had a chance to shoot one of these guns yet.  I’d like a chance to, but so far that opportunity has not yet been realized.  Perhaps at some point in the future, but for now, I can dream.  These guns definitely offer the shooter an interesting way to run multiple calibers while maintaining a single serial number.  Some people will not like this design, but I like it.
