    This is an actual review:
    I am very impressed with this upper and have fired 500 rounds through it so far without a flaw. I started shooting the barrel right out of the package as I saw no excessive oil or grease packed in there. I shot 200 rounds to break it in properly and washed everything with warm water and soap. I was amazed at the very little carbon built up compared to oiled rifles. The neck on the bolt was easily cleaned and had about 1/3 of the carbon normally seen there and that’s the worse spot for accumulation to occur. I took the rifle out again and it performed with even tighter groups using both 55 grain and 62. I wasn’t expecting for this barrel to be that accurate but I managed to keep shots within a quarter at 100 meters and within a 2-3 inch group out around 200 yards/meters. I used a BFS trigger and dumped 3 full magazines within a minute and not a single malfunction! The only complaint I have is that the EXT forearm gets extremely hot compared to others but that’s why I have a vertical grip on the rail and wear gloves. I have built 3 other AR’s that cost twice as much but this is now my primary (AR) weapon of choice. If only we had these during my combat days in Iraq/Afghanistan. Anderson is true game changer! Thanks guys and keep up the good work!

    To add to my review above, I mentioned the EXT forearm getting hotter than normal but I forgot to say that this is one the lightest forearm made and therefore my lightest weapon yet, so naturally there will be a trade off. weight vs. heat
