Hey everyone. I have a carbine length Smith and Wesson M&P 15, which has an aftermarket YHM gas block. WHen I installed the gas block, I used my existing gas tube.
I would like to have a couple extra tubes in case of failure (I know, unlikely).
Is this the proper item as long as I select carbine?: http://www.midwayusa.com/product/997...la=ProductDesc
