Does not feed into magazine well smoothly. - ProMag AR-15/M16 10 Round .223/5.56x45mm Rifle Magazine

I had to double tap it so it would properly fit into the magazine well. Also, when releasing and taking out of the well, it get stuck and you would have to use assisted by pulling it out. Bought this because of the FDE color that would match my all FDE AR, but no point if its jamming all the time.
