Not at all......
The UPPER receiver takes all of the CUP pressure in the firing of the round. The lower receiver in simplistic terms is nothing more than the trigger group and a magazine well.
My best guess is that if the lower rec. was going to break, it would break where the buffer tube screws into the lower. In fact real Nam A1 receivers are less beefy in this area and that's why the change when they went to the A2.
It might just be me, but I'd much rather get an AK on the black market than go through the hassle of buying and modifying a GBB...
But that's what I'm trying to tell you.........it's not a hassle at all. It would take all of 30 seconds to pop the GBB upper off and slam a real steel upper onto the GBB lower, since they DO mate up.
I can buy real steel uppers through the mail........no biggie. But the FFL controlled "firearm" of a M4/M16 platform is the lower receiver. It's just the way it is......
I can see exactly why the BATF is doing back flips over GBB airsoft rifles. They are introducing a non FFL controlled FULL AUTO lower rec. into the market. A receiver that in all likely hood is capable of mating to and controlling a real upper receiver, in both semi and full auto mode.
If the mfg's simply produce something that in no way, shape or form, mates up to a real steel upper? Problem solved. End of story.
Some blank fire company's actually produce a gun that fires the blank BACKWARDS. So that there is no possible way of creating a real firearm out of one. Some sort of thinking along these lines is needed.
