  1. Quinn S.

    I was extreamly happy with the quality my only complaint is the the gas tube would not fit with the barrel nut that was included but I was able to tourq it down and dremel out a valley for it to sit without touching

    these are great however, they need to come with a modified barrel nut, adjustable gas block and short bufferless tube kit in order to be complete in my opinion. No big deal just expect to mod the barrel nut after torquing, add an adjustable gas block and do something about the disproportionately large (but average) buffer tube.
