I just built 2 AR15 pistols for something to do.
One is a 5.56 and the other is a 300 Blackout, the 5.56 has a 7.5 in barrel and the 300 Blackout has a 10.5 in.barrel.
They are sure fun to shoot and looks like they will make a great survival gun for the airplane.
Just wondering if there is any interest out there ? They are easy to build and the cost isn't much more than buying a Glock.
