(5 out of 5) Great value lower.
by from Naperville, IL on

Purchased for my first build. I was impressed with the anodized finish, very smooth nice looking. Trigger crisp tight 8lb pull. I purchased second one. The finish was not as nice or smooth. I guess it's the luck of the draw. Still a great value.

(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.
