Modular? Interchangable? Anybody ever?

[BigSam]

MGI modular interchangable lower and an upper with a quick change barrel system.
Anyone have any experience with them or info on them that I can look up outside of their site?

I would think that with all this modular stuff, with hard use it could get kind of ricketty.
Anyone?

Shot at a demo full auto 45ACP here in CA -- was going to go to VEgas and try out the whole rage of calibers -- but they may not have any test guns left with all this buying --



Rainbow of brass with no stumbles -- They had the 7.62X39 conversion kit there -- it looked to be of the HIGHEST quality -- the whole mag well switches out --

I have their older version upper (tube with attached rails). I do not have the lower. I am not done with the build but it seems to be solid. Waiting on a barrel from an unnamed individual...
