(5 out of 5) Great Lower
by from La Plata, MD on

This is my third purchase from Sportsman Outdoors. I can't express how great customer service and overall experience is with SOS. Purchased this lower for my AR 15 build and it fits my upper assembly like a glove. There is no wiggle or spacing issues whatsoever with my upper. This is my go-to store for all my firearms purchases.
