    Intermediate buffer

    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!

    I installed this on an 18in mid length 6.5 Grendel build. Reliability has been 100%. Zero feed or ejection issues and the recoil impulse is as soft as my BCM 14.5 middy carbine. Great addition to this build.

    This is the 2nd item I've purchased from Bravo Company and as always, it was top notch. Thanks for providing great products at decent prices.

    Title says it all, with a standard a2 flash hider. Might try a heavier buffer for different ammo
