My plastic framed firearms are very durable. They can't corrode (even stainless steel will rust), they don't suffer from thermal stress, and they are very shock resistant. They are also more ergonomic and inexpensive to produce than steel firearms. Polymer firearms are supplanting steel firearms in the same way that composite aircraft are replacing aluminum aircraft.
Furthermore, none of them have been used in any assassination attempts. Your ignorant and inflammatory language in a public forum undermines support for our constitution's second amendment.
The law's value lies in maintaining the viability of xray detectors.
Terrorist's have always been able to get their guns where they want them, yet few terrorists still use them at all. Furthermore, firearms are detectable by x-rays, just like all matter is (as everyone who has ever had a dental x-ray knows). Your fallacious strawman argument that this legislation has to do with x-ray equipment is as wrong as everything else you've said here. The statue's intent is to make all firearms set off the induction based walk through metal detectors, not the luggage screening x-ray machines. These antiquated metal detectors can be defeated by active induction cancellation regardless how much metal is in the firearm and will soon be replaced with other technologies.
The law dates from 1988 on. I can formulate an xray dense polymer frame, why can't you. Apparently Bushmaster can and so can Glock, else their catalog items wouldn't be for sale.
None of these firearm's use "x-ray dense polymers" since x-ray absorbency isn't at issue.
If you understood physics, materials science and firearms engineering you wouldn't be making these statements.
It's clear from your statements above about "xrays" that you understand none of these in this context. Using the same sort of tortured logic you've used above, black powder doesn't show up in either screening test. So, by your same tortured logic, black powder must be a "terrorist substance" that should also be banned.
What is our Nations legacy? What do you know about my efforts to preserve it?
Our nation is unique in our ability to buy and posses the means to defend ourselves and our liberties. These rights have been lost everywhere else, one step at a time, by misguided people like you. By undermining this legacy, you squander everyone's inheritance.
"(1) which is not as detectable as the Security Exemplar (after the removal of grips, stocks, and magazines) by walk-through metal detectors calibrated and operated to detect the Exemplar;or (2) of which any major component, when subjected to inspection by x-ray machines commonly used at airports, does not generate an image that accurately depicts the shape of the component."
Are lawful items under this law.
"they don't suffer from thermal stress,
Everything suffers from thermal stress, especially plastics when compared to metal. Plastics also have lower strengths.
"and they are very shock resistant."
Compared to what? What's the application and alternative materials? Does the design matter? ...ect.
"They are also more ergonomic and inexpensive to produce than steel firearms."
Ergonomic? What are the design parameters and engineering alternates? Cheap! Yes, injection molded plastics are cheap. Composites are a little more. "Polymer firearms are supplanting steel firearms in the same way that composite aircraft are replacing aluminum aircraft."
Maybe you've been reading too many marketing hype. Composites have a use, but they are not replacing much Al, or Ti in aircraft. Consider the NY jet crash a couple weeks after 911. The tail fell off. That's, because they failed to really comprehend the nature of C composites. I prefer a steel frame 45, it's much more rugged, robust and reliable then anything built with plastic, or carbon.
"Your ignorant and inflammatory language in a public forum undermines support for our constitution's second amendment."
Sure it does.
"These antiquated metal detectors can be defeated by active induction cancellation"
WIth much trouble and inside info.
" So, by your same tortured logic, black powder must be a "terrorist substance" that should also be banned."
It's not tortured logic. The govm't doesn't want firearms in some locations. THey have detectors and other means to prevent them from getting in. The same goes for black powder. Black powder isn't supposed to be in those areas either and they have detectors and methods to prevent it.
" These rights have been lost everywhere else, one step at a time, by misguided people like you. By undermining this legacy, you squander everyone's inheritance.
Nah.
" Our nation is unique in our ability to buy and posses the means to defend ourselves and our liberties."
Like I said before, I'm interested in defending against air and mech armor attack, not piddling over nonsense.
lawful under this law.
