Not sure how. This is the Practical section of the form correct? Anyone who is of the opinion that a rifle designed at the end of WW2 was at the pinnacle of its design then they should also believe that the garand was the only rifle the US army should ever have been issued or that the P51 Mustang was all the fighter plan that the US army air core needed. I doubt that anyone believes these things so why is it that we must keep the AK47 and AKM "original" when we can make them better. Now there are a lot of crap products out there and I am not looking for a "Tacticool" gun. What I am asking is has anyone used this product and if so is it just some nifty little piece of junk or is it something practical that could add value to an already awesome weapon. Thus it is in the "Practical" section. Now there is a time and a place for a traditional AKM, but the rifle I am modding is not that.Might be barking up the wrong tree, around here.
