Have been doing some late season shopping and I had a feeling that there were still gonna be versions of rifles I could acquire. Now, I have done a few searches on the 556R made by sig, it's not specifically banned by name, my curiosity is if I get my deal to pin the stock, (Gun still has flash hider) is it legal for me to purchase, and is it legal for me to purchase out of state (delaware)? I was just curious as pinning the stock will mean it only has 1 of the "evil rifle" characteristics.
