In a world of 14.5" uppers one man pins on a 20"

[snipecatcher]

There is no restriction on barrel length for a pistol. If you were to buy an AR pistol, and put that 7.5" upper on a lower with a butt-stock, you would have a SBR. You would need a stamp for that. As long as there is no butt-stock and the lower is registered as a pistol, you can put whatever length barrel you want. Registered as a rifle and it must have a 16" barrel*

*The "barrel" doesn't necessarily need to be 16", but must be in such a way that it cannot be made shorter than 16" without cutting, tools, etc. You could have a 10.5" barrel with a 6" permanently attached flash hider and be legal.

Could someone please measure their 20" AR from butt to muzzle? I'd like to compare it to my other rifles (Garand, etc).

Haven't gotten rail covers and a forward stop yet.

Oh and a VCAS sling with DD A2 ambi sling loop adapter. I prefer a relatively KISS rifle.
