Troys folding sights - Troy 45 Degree Folding Battle Sights HK Front/Round Rear Iron Sights

I could not be more satisfied. The previous 45 degree iron sights I purchased were difficult to zero in and broke after three times of usage! After installing these purchased by optics planet took less than 20 minutes to put on and zero in. Also, I’m very hard on my equipment and thought after dropping the rifle, they would’ve broken, but they’re very resilient! Thank you and I highly recommend
