Awesome product. Does exactly what it says it will do. I got the three pack and a single piece was missing. I contacted you folks to ask how I should proceed, and before I knew it, you had sent me a complete replacement package, no questions asked....amazing customer service. I've ordered from you folks before, I'll definitely do it again!
Easy install, Feel more confident in rack cycle.
Should throw-em out consistent.
Thank you for offering such a quality product.
I installed the new spring into my bolt
The whole take down and install took about 5 minutes very easy,
Since the spring upgrade I have shot roughly 350 rounds through it , I had no issues no more double feeds no anything
Ar is good now , I thought I had bad magazines and I almost a new bolt
It was just a $5 dollar spring that was wore out
Spring upgrade is awesome
I always use these for any new bolts I buy.
What else can be said, perfect upgrade for bolts that do not have this, as all bolts should. A must for pistol builds. High quality like all of BCM parts.
I purchased this kit to fix a jamming/stove-piping issue I was having with a new AR-15. At least once every 5 rounds a spent cartridge would not be fully ejected and would get stuck sticking out of the ejection port as the bolt was attempting to chamber the next round. This fixed the problem! I'll be updating my other ARs soon with the remaining springs from this kit.
Ar pistol was having trouble ejecting shells without jamming every other one so I got this kit and installed it eliminated the problem and cycled like a champ. This is a must for the shorter barreled rifles small price for a big problem. Thanks bravo company
great product that WORKS
This is a guaranteed item that will keep your bolt carrier group up and running.
