M4 double side feed ramp or single middle feed ramp ??? Thank you — 2 Answers

I see no feed ramp on the product page. Actually, if using on AR glock fed lower, there is 1/4 inch gap between barrel face( extension) and the 1st bullet loaded in a glock magazine. I ordered feed ramp from taccom for 20 dollars to fix this problem. Gun kept miss feeding, jamming without this special made feed ramp from tac com. Only problem i had to mill out a little section on my upper receiver to accept this feed ramp. You can do it with a file if you don't have a milling machine. Anyway, it feeds perfect now. Tac com fixed a flawed design. You don't have this problem on a colt magazine fed AR 9mm because they come with a feed ramp and a place to put it in your AR 9mm colt style mag fed lower. I have 2 glock mag fed AR 9mm and 1 colt fed magazine AR 9MM LOWER. THR COLT style lower is 100 percent more reliable. Its a flaw in the glock style AR 9mm lower. Taccom came up with a solution that works though. I hope this helps someone
