Great value, good quality finish

It has everything you need for an oops kit, or a new build when you’re customizing the lower parts hardware (bolt catch, safety, trigger, etc) and a nice black finish on all the parts. And the price is right!

Top quality low price

Thanks again to Primary Arms for delivering top notch products with top notch service for dirt cheap prices. I bought this kit on Thursday and got it Friday before noon. Of course I live in Texas, but the fact that they work so fast is the reason why I will only do business with them! Plus the small parts kit by Expo is top quality. Everything fits perfect! God bless America and God bless the people at Primary Arms.
