    My new BCG was shipped fast, wrapped up nicely. I took it apart, lubed it lightly with CLP, and hit the range. seems to work solid. looking forward to using it more. Thanks for making a great product!

  2. Anthony Royster (verified owner)

    I called customer service to place two different orders and it was a great experience. I ordered a BCG and I got it in three days. The second BCG that I wanted they took it out of production but they still took the time to contact there suppliers and find the BCG that l wanted and still get it to me in three days. The XPB and the Balanced BCG work great and I couldn’t be happier.( extremely impressed ).

    Having purchased a Balance Bolt with Reli-bolt for a rifle I built in 2016 and really liking the performance, i decided that it was time to update a previous build, so I once again went the purchase the same thing, but discovered that it had been replaced with the more updated XPB. It was a great buy, and I look forward to shooting with it soon.

    Paid for a FDE XPB carrier group, but instead received a black one. Decided to keep it and order another in the near future. A FLAT DARK EARTH one! Other than that, it’s one smooth bolt carrier. Awesome.

  5. Brian Pearson (verified owner)

    This BCG is a nice addition to my camo painted rifle. I bought the FDE color. The BCG was the thing left that was black. Fit and finish is just beautiful. Bring that its made of all S7 I’m looking forward to abusing the hell out of it. Thanks Sharps Rifle Co.

  6. Toshio (verified owner)

    Product is stellar.
    Great quality and finish workmanship.
    I think SRC is still one of the best-kept secrets in AR products, and I’m glad your product is gaining more publicity throughout YouTube, which is where I learned about it.

    Only request for improvement would have been a shipment notification – somehow I did not receive one.

    Great job overall.

    I bought the FDE bolt carrier group for the pure awesomeness and it makes my FDE AR15 look Gucci Gucci. Been using carpenter steel BCGs (no frills just robust) kind and let me tell you, actuating the charging handle is 40% smoother. This gives me a huge impression that cycling will be smooth like my, now, Gucci FDE AR15.

  8. Keith Morgan (verified owner)

    Easy and fast ordering experience. Fast shipping and quality product. Would recommend to others.

  9. Cliffton Sullivan (verified owner)

    Great products and will be buying another one soon thanks

  10. Robert E. (verified owner)

    Exactly what I was wanting. Shipped fast, great BCG!

  11. Daniel (verified owner)

    Used the BCG for a couple range sessions zero malfunctions only time will tell as I continue to use the BCG only have 290 rounds but so far so good.

  12. pedro ulloa (verified owner)

    Looks great on my tan ar that I just built I’ll probably go shooting soon beware evil doers

  13. Darell Shaw (verified owner)

    Very good product, just over 600 rounds no issues.

  14. Joe Grunt

    I’ve been waiting almost 3 months for the FDE version to be restocked. WTF Sharpes? Bring back the FDE Reliabolt system.

  15. James Burrola (verified owner)

    Recieved the BCG quickly. The FDE is a great look. Looking forward to firing it in the future. Still building my upper. Will give my take on how it preforms in the near future.

  16. Everett Hunt

    I have years of experience with the M-16/M-4/AR-15 platform from my military service. Typical Mil-Spec BCGs have a “clunky” feel to them. These literally are the smoothest actuating BCGs I have ever fired!

    I was fortunate enough to acquire two Balanced Bolt Carriers (BBC) in NP3 before they were discontinued, and I have always been impressed with how perfectly and steadily they ran. So I made the decision to purchase two of the new XPBs in either coating, the Diamond Like Coating (DLC) with the Hyper Black polish, & the FDE Zirconium Nitride (ZrN) coating. WOW!

    SRC continues to impress with their products! SRC’s design is precisely what was needed to drop the fouling and failure rates of this rifle platform to zero and NOT break the bank! This is the best improvement ever made for the AR-15! Excellent job SRC! If you are considering purchasing either of these XPBs for your AR, you WILL NOT be disappointed!

  17. Matthew Urioste (verified owner)

    Just received My BCG built from S7 tool great product over built to the point of being bomb proof and to top it off fast shipping

  18. Omar Ahmed (verified owner)

    I want to thank you all for processing my order. It was easy and fast. I have not built up the AR yet because of delays in parts from other suppliers. However once it’s done I will give you guys a full feedback on the BCG.

  19. Chris Mullins (verified owner)

    Excellent company, quick to ship and amazing quality!

  20. Josiah (verified owner)

    I bought this BCG knowing it was going to be good, but I was still surprised by how good it was after putting about 100 rounds through it. The ZrN coating is very effective at protecting from carbon build up. The carbon wipes right off in most cases, and after an actual cleaning it looks brand new again. Aesthetically, it’s the best looking BCG that I’ve seen. The FDE inside the black upper receiver looks outstanding. I’m very happy with my purchase, and I’ll be a returning customer.

  22. David (verified owner)

    Best BCG!!! Fits perfect no problems exactly as stated in description. Money well spent. Will be buying another one.

  23. Brett (verified owner)

    Have 4 of ’em – buy no others, Sharps’ BCG’s are indestructible compared to competitors…and usually at half the competitors price points! I typically go with the “buy once cry once” theory but Sharps has nailed it with these – and I’d pay double for ’em if that’s how SRC priced ’em. Do some metallurgy, structural integrity, and non-destructive / destructive research on the materials SRC uses vs. what others use and you’ll understand why…and then buy!

  24. Rodney Painter (verified owner)

    Amazing quality, I love the BCG. It feels great and shoots amazing. Highly highly suggest for anyone wanting an upgraded BCG. Wonderful product and great price.

  25. Larry Mackey (verified owner)

    Again very happy with the quality.

  26. Joseph Mikus (verified owner)

    Top of the line. Love this thing! Oh yeah and the shipping was Fast! Keep up the quality and Thank You!

  27. Jason (verified owner)

    Well done coating! Really excited about the FDE and extremely well made product and a pure joy to have the quality of Sharps. This is the 5th Bolt carrier group I purchased from Sharps and will continue to buy more when I need them.

  28. Robert Pezanko JR (verified owner)

    The quality of this piece is flat out awesome and is a piece of ART!! looks simply amazing. Top notch quality and fit and finish. Super fast shipping and great communication… Thanks SRC

  29. Jordan Lindo (verified owner)

    Easy to install, easy to clean, aesthetically pleasing and have no issues running .300blk on it. Am definitely looking to buy another one in the near future.

  30. Jonathan Stopa (verified owner)

    Nice finish extremely well-made
    thanks

  31. Romik Petrosian (verified owner)

    I got a FDE bolt for my AR15 and I love it. it is perfect fit on my two tone AR15. the Bolt is very high quality build. I will recommend this to all if they are looking for best parts for their AR15

  32. GLEN HERNANDEZ (verified owner)

    Happy with this product.

  33. Mark Walker (verified owner)

    These bolts are well constructed and perform very well. I noticed the difference in the first rifle I converted.

  34. Thomas Fisher (verified owner)

    Have not fired this yet. installed in firearm and weather is bad. Quality piece as all Sharp’s products are. Running four now have another build ,parts, ordered and this is the carrier for this upper.

  35. Sean (verified owner)

    Great product and fast shipping!

  36. RICHARD moses (verified owner)

    Had a few jam ups at first. Very frustrating. Then it seemed to break in . I shot 150 rounds and I think the last 130 were without incident. Time will tell. Thank you
