Northtech Defense's passion is to produce high quality, perfectly manufactured, and leading edge designed products for the firearm industry; including Military, Law Enforcement and the Civilian market. Each lower is meticulously inspected for quality control and is built to work seamlessly with our billet upper receiver. Our billet lower is stylized and balanced to perfectly compliment our billet upper receiver. Northtech Defenses billet upper receiver was created to be perfectly matched to our billet lower .

my one complaint...Review by daytonasooner86
Great upper and lower, getting all the internals in it was no problem, seems to fit pretty snug together and doesn't rattle. My one complaint though is that it scratches easier than i would have expected. it came with a few minor scratches in shipping. that said though, it is a quality upper/lower (Posted on 4/9/2015)
One flawReview by Larry
This is a great billet receiver combo, only one thing, it will not accept a BA Ambi release. (Posted on 12/15/2014)
