I have owned an ar-15 but never built one. With all the craze I purchased a stripped lower and now plan on building it. I have a question and I have looked around and cannot find the answer.
I purchased a S&W M&P15 lower and while looking around for a trigger group I found that they make large pin and small pin lowers. I do not have anything to measure with other than a standard tape measure so tought to actually measure the holes but on the m&p they look slightly larger than on the bushmaster xm15-e2s model. I cannot be sure though and that is why I am asking. Sorry for the question if it is a dumb one but I don't know so I gotta ask. Anyways my question is, how do I find out what size pin holes come on that model of lower? |
