XPB BCG August 20, 2017
Reviewer: Gregory Martin from Arvada, CO United States  
Bought this when it first came out at almost full retail. Was scared I tossed money away on snake oil. Now 3k rounds later I have no regrets. Runs great, easy to clean, not one malfunction in a 10.3 barrel.

Love Sharps August 6, 2017
Reviewer: Jeremy from Wyoming, MI United States  
I built my AR back in 09 from a Sharps stripped lower. I was in the market for a nickle boron bolt and found one pretty cheap. On a whim I thought I would see what other Sharps products were available. I found the XPB on sale. The logo matches with the lower making it look almost like a dedicated Sharps AR15. I wish had a magpul magazine with the Sharps logo to go with my Sharps AR. Ok so a great looking doesn't mean much so lets talk performance. I shoot about 500 rounds with no lubrication on the bolt with zero malfunctions. It cleaned right up with a rag. I wish there were more color options for the XPB. Right now it's only black and FDE. Like I said I was looking for a nickle boron bolt and I was going to buy Sharps silver colored bolt but it's discontinued. The XPB also has a unique shape that when I compared it to my old BCG I realized there's less wear inside my upper. There are stabilizer fins in the back to reduce the chance of bolt bounce.
