This is an awesome product. I will not be buying plain mil-spec lowers anymore.....i think NFA does a great job on quality and service. Thank you and I will be ordering more

Very well made lower
I’ve used New Frontier lowers before and have been very satisfied with them. I was particularly pleased to find the Allen screw keeper for the takedown spring and detent was provided although I’d already purchased a supply of them.

As a manufacturer of firearms, this is the best looking and most "user friendly" lower I've ever had the pleasure to work with. With the lower to upper tension screw, you can throw away those silly "accu-wedge" shims. The takedown pin spring set screw makes the assembly of the receiver extension a breeze. The threaded bolt catch pin removes the extra work and care required to set the old style roll pins without damaging the finish on the lower. Anti-walk trigger pins fit more exactly to the somewhat wider width of the lower's exterior dimensions. The select fire marking is great for those fire control drop-ins such as the Tac-con 3MR. New Frontier is a great company with industry leading innovations such as the side charge billet upper.
