    One of the best upgrades available

    Slightly softer recoil impulse, more reliability and longer overall length of pull, what’s not to love??

    Being new to AR builds I dont really know too much about buffer systems. I bought this one on a recommendation from a friend. I can say that on my BCM 14.5 build it ran flawlessly. I would recommend this and will be purchasing another for a future build.

    Intermediate buffer

    Posted by anonymous on Jul 17th 2019

    Seems to work good. I've only put 30 rounds through a 16" upper and 30 through a 20" upper with no malfunction. Installation is straight forward. Staking the castle nut and end plate was pretty simple with a punch.

    Excellent Fit and finish. Couldn’t be more pleased with the product. It’s clear Bravo Company has an eye for details. I’m happy to support a company that takes quality seriously and supports veterans!
