No longer offer a lifetime warranty on their products. I am trying to exchange two BCG with poor machining and both sunny state and sharps are radio silent
Wow, 90 day warranty now! Thanks for posting, I was about to buy a xpb bcg. Back to researching which to buy again, definitely never buying something only warranted for 90 days, that tells me they have no faith in their own products.
There is nothing to research. Buy anything milspec with the coating of your choice.
This arms race of uber-BCGs is ridiculous and needless.
If you are out there destroying MILSPEC BCGs, there is something wrong with your setup or you don't know how to clean a BCG.
Hi Phoenixrising, just want to make sure all is well with the replacements we sent you. Thanks again for the purchase!
Sharps DLC BCG's are grade A products just remember to clean that lug-locking chamber every few thousand rounds :-p
They no longer offer a lifetime warranty on their BCGs
Not hearing anything back from sharps but sunnystate is stepping up to help
DLC is not for "diamond like carbon."
It is for diamond like coating. And DLC is not carbon.
Sharps is correct in their naming of this bolt. Here are a couple links describing the properties of Diamond like carbon coatings:

Why not just buy another BCG and get the bolt for free at this price?
Who are they selling these things to, people who have somehow managed to destroy a bolt?
