I just bought an upper from Hardened Arms. I couldn't find much info on them when I was shopping for my new upper, so I thought I would do a quick review. I contacted three companies that sell uppers in 7.62x39, the caliber I was looking for. The first company said it would be 3-6 months before my order would ship. The second company said 5 days if the upper I wanted was in stock. Hardened Arms told me 48 hours from order to shipping, if the upper I wanted was in stock, and their in Washington so I knew I wouldn't be waiting forever on shipping. I ordered my upper on a Monday evening, it shipped Wednesday and was in my hands Thursday. I finally got a chance to put some rounds through it today, 40 rounds of Tula, I had 2 FTL and 2 FTF. On the FTL when I slapped the bottom of the magazine the bolt closed and loaded the next round. On the 2 FTF I opened the bolt half way, let it close, and the rounds fired. Overall I happy with my purchase, I wanted an affordable AR that would be cheap to shoot, but still legal to hunt deer with in WA and this fits the bill.
