Great Looking BCG November 23, 2017
Reviewer: Robert Jones from Clayton, NC United States  
I have not had a chance yet to make it to the range with my rifle build and the Sharps Rifle bcg.  However the workmanship is terrific.  In working the charge handle on my AR, this bcg is a very smooth operating component.
