Outstanding deal on a great BCG

by

I purchased the FailZero EXO (Nickel Boron Coated) M16 BCG from Primary Arms. I found their price completely unbeatable. The BCG arrived very quickly in the mail. The produce was as described and a very high quality product. The BCG slipped right in my AR with zero issues and will serve me very well. Thanks Primary Arms for once again a good deal and great transaction!

Wasted Money

by

I used on a BCM upper and on the second shot the bolt jam. I had to hammer out the bcg. Even put plenty of lube before going out to the range. Will never buy again.

Fail Zero M16 M4 Bolt Carrier Group (No Hammer)

by

Initial impressions are what I expected on this FZ BCG. Not many rounds with it yet, the build was stripped for cerakoting after I verified the overall functionality of the rifle. Packaged well, shipped in a timely fashion. Primary Arms is my new go to favorite for parts and accessories.

Best deal out there.

It's amazing how much effort and time you will save when cleaning your AR 15 with this bolt carrier group. After hundreds of rounds the bolt/carrier just wipes clean... Not to mention how little lubricant you need for flawless function. I recommend this for any AR build or upgrade. You will be impressed.

Great Bolt

by

Just completed 16 inch 300 Blackout. Bolt works flawless along with Bravo Mod 4 Charging Handle, and JP Captured Spring. Ran over 200 rounds through it already and it runs smooth and quiet with the new spring.
