This is a rare chance to own a piece of history. This upper was used in the Coast Guard trials in about 2008 range when they were looking for a conversion upper kit that would be able to take out an outboard engine and other uses. This is chambered in .499 LWR and uses a standard M16 carrier and 7.62x39 bolt. These were field tested guns and they had issues with feeding so they ground the feedramps in order to make the larger caliber feed better in standard uppers. This will fit any standard m16/ar lower and the mags will also fit in standard mag well. They are single stack round mags made as s custom order by PRI for these tests. I will include all 3 mags seen. They do have rust areas on them as they were used in salt water environments. This is the last upper i am selling as it does have the Leitner Wise logo on the upper and .499 LWR on the side of the upper. This is not a parts built upper but is facotry and it being sold as is. You can get and reload the ammo as well if you have the desire to shoot it. You can also read up on the program in the Black Rifle II where Chris Bartocci was at the tests and wrote about them.
