The HK 416 is a 22LR AR15 clone. It is a very high quality rifle manufactured by Walther licensed by HK. I purchased this rifle three or four years ago and a friend of mine had one and told me that he fired four thousand rounds through his HK before cleaning it without any misfires. I listened, but I thought you cannot fire a thousand rounds of 22LR without misfires 22LR is a dirty ammunition. I was wrong! I went through about three thousand rounds without a misfire before I cleaned it. This is a great rifle to train young people to shoot an an AR15 without recoil and an extremely low cost of ammo. I enclosed a couple of photos of the 416. I started with a very inexpensive red dot Sig and changed to an illuminated red and green inexpensive Sig scope. I posted a You Tube informant and entertaining video.
