best upgrade June 19, 2017
Reviewer: Francisco Valles from Los Angeles , CA United States  
the bcg that my ruger came with was broken out of the box, after some research i made my choice and went with the XBP bcg and i couldn't be happier, this is the best upgrade to my AR, and the cherry on top is the price, i got more than what i paid for

Quick service and quality product June 9, 2017
Reviewer: O-6 from Maxwell AFB, AL United States  
If you're shopping for the ultimate BCG, you probably already know everything you need about Sharps. I knew I wanted this product, and it was quick, easy, and on sale to buy direct. It was only 2 days from mouse click to in my mailbox. Buy with confidence for the best BCG made.

Review of XPB Carrier Group June 5, 2017
Reviewer: Richard Sanchez from Tampa, FL United States  
I received the carrier and took it to the range as soon as I could. It worked perfectly and is the best BCG I have ever used. I expect many years of use from it. It's easy to clean as well.
