"I mounted this sight on my Stag arms model 3 gas block. It works well with the detachable carry handle. I have not had a problem with it returning to zero. The only problem I had is if you mount it to the gas block the proper way, where it folds back towards you, it wont fold completely and will hit the handguard. It was a simple fix and I mounted mine where it folds foward away from you. All in all, this is a good reliable sight for the money."

"I have this on my DPMS sportical and works fine, I only had one problem with it needing more blue thread locker because evidently it wiggled free. Never had any problems after. Made from good material and you can tell it won't move after its locked into place. Easy to move when you want it too. Works perfect because it is designed to fit on a gas block rail while still being standard profile."

"This is a great sight for an AR platform. It folds down nicely and is solid in its movements. When you already have a gas block installed (as per my Stag Model 3), this is an awesome sight. I've had it on the range numerous times without any migration. This Yankee Hill sight is a great fall back iron when the upper is geared for optics. I would purchase it again without question."

"I have this on my 16\" Stag LH and it works very well. It folds down out of the way for my red dot sight but can be raised and locked quickly. It has solid construction and can take abuse. CTD had the best price I could find."
