About HOLOSUN - HE510C-GR Open Reflex Optical Sight
67% liked the mounting compatibility
I was able to sight the 510 at the range using the included tool and achieved good groupings.
80% appreciated the adjustment mechanism, while 20% disagreed
I found the adjustment mechanism and mounting of this gun-sight to be easy. After zeroing it on my 300 AAC AR, I removed and re-installed it using the quick lockdown lever without losing my zero.
After only 400 rounds, the QD mount starts separating from the optic and is ready to fall off. This has caused me to lose confidence in the product's reliability.
