I mean convoluted in practicality. I can have a totally clear lower and then throw a ghillie wrap over it and the gun would likely be indistinguishable from the real gun. It's not important and it is off topic so I won't list like 100 ways I can make a clear lower on an AR-15 disappear.
Thanks for all the practical and excellent advice guys. I'll just stick to some Canadian market guns for now and maybe by time I feel a serious need for something rare it will be readily available on our market.
