    Awesome quality product. Perfect railing for my needs. I had to shave down about 3 millimeters to make them fit. In a way I’m glad that I had to tho because I made them fit exactly how tight I wanted. Comes with inner heat shield. OD green is perfect color. Same, if not better quality as OEM handguards. Slightly smaller profile than OEM, perfect. I was going to give 4 stars cause of fit but it turned out better I think. It has two notches on each side to prevent movement. No movement at all and fit perfectly tight. I cant say enough great things about these hand guards. Also, i recieved it way faster than expected. Great job Zahal.
