NcSTAR US Force AR-15/M16 Scope Mount

I was looking for a cheap way to mount a scope on my ar-15 without going through all the hassle and expense of installing a flat top receiver. This was the perfect solution to my problem.

It came in a nice sturdy little box which can be saved for later storage. The mount seems to be very well built and fits snugly into the carry handle. It was actually a little too snug and i made a very deep scratch in the finish when i first installed it( a little lube will probably fix this problem). After that simply hand tightening the nut onto the screw seems to be sufficient to hold it in place. I've put 500 rounds through my rifle so far and it hasn't needed tightening.

Problems i had:
1. The item is labeled on amazon as a weaver rail when it is in fact a picatinny rail. The difference between these is that the slot spacing on a weaver is 3.8mm and on a picatinny its 5mm. This can cause a problem when you're expecting a weaver rail and order rings that lock into the slots ahead of time WARNE 200M 1IN RINGS LOW MAT . The rings still work because they have side screws that tighten but the whole reason i bought them was that they locked into the slot. So just be warned it's NOT a weaver rail.

2. The price of the item is a very good deal but the shipping rates of the two companies that sell it on amazon are insane. If you find it anywhere else it will probably be more expensive but id go for it just to avoid paying their exorbitant shipping costs.

Other than that, the see through iron sights just take a little getting used to. But thats something i think all see through mounting systems require and not a specific problem with this product.
