It's much smoother than Hard Chrome, it's easier to clean and you can run it almost lube free for thousands of rounds due to it's self lubricating properties.

5 of 5 Great Value January 1, 2020
: Scott Harris from Danville, VA United States  
I shopped around and found this one for a low price and its everything I imagined it would be. Super slick and smooth. I didnt analyze every cut and corner but performed as expected for a great price.

5 of 5 very smooth December 13, 2019

BCG slides very smoothly and locks up tight.  Ejection is nice.  Seems like a good bang for the buck

Really love the coating on the nickel boron, shoots very good, shooting 200-500 yards definitely makes a difference compared to the original BCG.
