Really disappointed experience with this rifle.
The main problem is accuracy problem. The best group I can get is about 4 Inch size at 100 yard range. Big difference with the advertised under 1 MOA accuracy at 100 yard!!!! Evert shot was from bench rest. Tried most ammo from 40gr to 77 gr. Not my control problem, not optic problem, not optic base and ring problem. Nothing contact with the free float barrel.
Second, the bolt dust wiper was broken during normal shooting when I was trying to address the accuracy problem. Bad Quality!!!
Then when I Try to contact Adcor customer service, it is also terrible!!! Send 4 emails wrote about the two problems above NONE of them replied!! NO reply !!!! Not late reply, I got NO REPLY !!!!!
Next I call them to see how to solve the problem, they answer it at my second call. It was quit good communication during the phone call, and they said they will send me a box so that I can return the upper to fix it. I accepted and filled out a form on their website as they request. Then I called them again to make sure they have my fill out form. They told me they have and I will get the box just in 2-3 days. After a week till now, I got nothing from them!!!! Called them over 30 time, no one answer!!!!
I don't know how are the others rifle they sold, What I got is just piece of JUNK!!! NOT even better than a $500 gas impingement AR!!!!
