Great product. Good finish, nice tight fit on my lower and, as I've come to expect from PA, very fast shipping.
Great quality and fit. Matched it to a Spikes lower.

Great quality, no worries with Spikes products. Fit function perfect. Primary Arms is the difference. Look no where else, because you won't find better customer service!!
