Kensigtht ak fiber optic sight - Kensight AK Fiber Optic Font Site Post Insert

I purchased the Kensight AK Fiber Optic Front and Rear sight for my Century RAS 47. The installation was easy and every thing went right. I used the red inserts, and it certainly made it easier for my eyes. Sight adjustment was just like the original AK and with a few turns it was hitting correctly. With care, and some protection, the sight will serve well, but it will not take the abuse and hard field test. I will purchase another one for my second AK.
