FailZero Nickel Boron EXO BCG

We're pleased to offer the FailZero EXO for sale, a bolt carrier group designed for the M16 but also preferred for M4 and AR15 builds. Requiring no lubrication for installation, the EXO NiB bolt carrier group fits perfectly into any upper receiver and provides smooth chambering with reduced friction between each round, thanks to its nickel boron coating. Although this full-mass bolt carrier group is heavier than your standard BCG, the added weight adds to the part's reliability and performance as it can withstand thousands of rounds before showing signs of wear.

We offer FailZero EXO BCG bulk discounts for dealers with guaranteed satisfaction and fast shipping. Read more about our dealer program to learn how you can get bulk discounts on FailZero EXO BCGs, and shop with RightToBear.com today.

3 of 5 Be aware of your gas tube length! January 31, 2021
Reviewer: Jeff R. from Arizona  
I ordered this for a rifle length gas tube and it fails to cycle rounds. I put it into my carbine length AR and it functions fine...actually very smooth. I adjusted springs and buffer weight trying to make it work, so I did my due diligence.
Right to bear...I like your website and products, but you really need to work on your customer service!

5 of 5 Slicker than whale s*** December 25, 2020
Reviewer: David Swenson from Crystal River, FL United States  
This BCG is outstanding! Slicker than whale S***. Fully coated inside and out on ALL parts of the BCG, super easy to clean very little lube needed and did I mention slick. A great addition to anyone looking to bullet proof their weapon. A great upgrade to my FN AR15 A4. RTBA you have a new customer, simply outstanding!

4 of 5 Fail zero bcg October 5, 2020
Reviewer: Alan from Chicago  
Nice looking solid bcg. Visually looks good. Staking is ok. Ive gone through a few hundred rounds with it and still looks good and fairly easy to clean. The only problem so far is the firing pin is extremely magnetic. It’s so bad that it was a challenge to put the pin back in place after cleaning because it sticks to the inside of the carrier. So that limits the ammo I can use with it. I think a lot of companies are overlooking magnetized parts. Other than that it’s ok so far.
