If you are making a true classic to resemble the M16A2 that i carried in the Marine Corps, why is the carry handle removable on this weapon when it was not on the weapon I carried? If it had a permanent carry handle, I would be interested in pruchasing one.

Great Rifle
A solid feeling and great looking rifle. It was exactly what I was looking for in my first AR-15. As a clone of the A2 rifle it doesn't get much better.

Awesome AR-15
This is exactly like the M-16 I had while in the military. Breaks down and goes back together exactly the same. Has a bayonet attachment and is highly accurate at 300+ yards when properly zeroed. I would highly recommend this weapon to anyone interested in a top of the line AR-15 that is closest to the M-16 you loved and fired while in the military.
