Excellent Product May 7, 2018
Reviewer: Anonymous Person from Etna, OH United States  
The XPB is a great BCG. The DLC finish is smooth to the touch, easy to clean, and operates perfectly. I purchased a blemish and could not find the blemish. If I didn’t know better I wouldn’t known any different. Definitely worth the money.

Sharps XPB Carrier Group Complete April 25, 2018
Reviewer: Paul from Denver, CO United States  
Ordered the blemished XPB Carrier Group.  Well packed and received in less than a week.  The BCG is quite awesome once you have it in your hands!  Very light blemishes on the rear of the carrier...which should not adversely affect performance.  This is part of a new build...looking forward to taking this to the range!  Thanks Sharps Rifle Company!!
