I don't know if that's one of the models, or not, but there were a couple AirSoft ARs capable of accepting AR upper receivers, a few years ago. With minor modifications to the lower, it became a fully-functioning (if short lived) firearm.
The ATF pushed to have their import banned, but the companies changed the design.
There are also two AirSoft pistols modeled after Glocks, that the ATF claims are "easily converted" to live firearms.
All you have to do is:
Install a fire control group
Install slide rails
Modify the mag well
Buy and install a slide, a barrel, and the recoil springs and guide rod
And reinforce the frame
So... basically, they're a plastic grip frame that you have to build a firearm around. THAT, to the ATF is "easily converted".
Several have been 'converted' by hobbyists, and they have an extremely short life span. -I think the most I've seen is 40 rounds, through one which was reinforced and built with well-engineered slide rails -- at the opposite end of the spectrum, one broke in half on the first test firing.
(I believe there are three on-going "Glock from Airsoft" builds going on here:
Home Gunsmith.)
