Ratings & Reviews
I have been waiting to try one of these Zero-Fail bolts for a long time. I finally bought this one but was disappointed when it arrived. The entire bolt has a "smokey" look. Looks similar to the stains on other NiB bolts that I have (after shooting). The carrier seems to be clean, just stained. The bolt had Carbon deposits all around the tail. I scraped off the carbon and cleaned the whole BCG. Will see how it performs when I get it to the range. It has Obviously been Used... Did not see THAT in the description.

I recently purchased this bcg for a 300blk build and it is awesome! Great quality and very smooth. Would purchase again!

I've put a couple hundred rounds through my gun with this BCG and have had no issues whatsoever. I have never ran it without any oil, it goes against nature for me to not oil everything. But overall I think it is a great BCG and I would definitely buy it again.

Looks real nice I haven't got to use it yet but did my research and this is the best BCG aroun. Easy to clean and feels real smooth the EXO technology looks like its a permanent lube over the bolt which will work out just nice. Can't wait to test this BCG out and see how much it can take!
Great customer service

My BCG was lost in the mail and replaced without question. Very appreciated! Nice BCG too!

My nickel boron BCG arrived quick and is a nice product, the Black Friday deal was hard to pass on.For a long while I as on the fence with NIB bolts and carriers, once I had one it grew on me like moss on a wet rock. Have a few now from WMD, LWRC to Failzero. They're all good and makes my life easier after shooting. So nice to be able to clean them quickly. PS, Ignore the manufacturer, all BCG's should be lubricated, nickel boron or not. A lubed firearm is a happy firearm and there's no exceptions at this time.

My third one of these, on sale they are a great deal and somewhat easier to clean. Don't believe the hype, you'll need to do more than wipe but they run great and clean up well.
