Scope mount - Primary Arms Classic Deluxe AR-15 Scope Mount

It's a lot cheaper than most one piece AR scopemounts but, like most anything, you get what you pay for. It mounted easy but that's the only thing I have positive to say about it. After I zeroed my rifle in at 25 yards, I backed off to 100 yards and couldn't get on the target. I checked the scope only to realize my scope was so loose I could take it off of the gun. So I I tried to tighten the mounts back and the two bolts had stripped so bad that it no longer looked like a threaded bolt. When it comes to your optics pay a little extra and you'll get a much better product
