Really high quality BUIS for the price. Well made and sturdy, would highly recommend!!
Work pretty well for the price point. Never could really get them zeroed in. Rear sight worked great. Couldn't get the front sight to adjust very well even with the sight tool. Still needed about 4 clicks down. Could see the adjustment was there just couldn't get the sight post to turn. Other than the front sight I would have given it 5 stars. So now I have to remember I'm high by 8 inches at 100 yards.
Good sights for the money, work great.
Delivery was ahead of time. The sights fit perfectly. Very good quality.
Put them on LR308 recoil makes them fold down no matter what direction you mount them bought 2 sets big mistake
