    Runs like a dream and eats the felt recoil.

    A quick change out from the lower weight buffer to this one. My 7.5 AR 9 on a MILSPEC lower ran like a champ. Two 30!round mag dumps and a sight in session. Next weekend is running the FRT.

    Perfect fix

    Built a AR-9 & buffer was too light & added weight of this buffer did the trick. Limits bolt travel & cycling is great. Highly recommend!

    Buffer has been solid in my Aero EPC9/KAK build. Been flawless paired with KAK flatwire carbine spring as well as BCG. Thanks KAK for making awesome products.

    Shot my weapon today and had no problem with the buffer and spring performance was i imagine. No issues and recoil were exceptional. Thank you

    Works as advertised...maybe even better.

    Acquired a H&R DOE pistol and heeded the wisdom of Blowback9. This requires an AR9 to increase the combined weight of the factory bolt and buffer to 22ozs or more. More being better. After using this buffer in conjunction with KAK's tungsten bolt weight, it brought the combined weight to 24.4ozs. This helps mitigate out of battery detonations due to bolt bounce and also slowing down the action to reduce felt recoil. On top of that, since this is the extended buffer, one can remove the over travel plug from the DOE's buffer spring. Now I can rapid fire and shoot suppressed without worrying about unwarranted explosions. So remember. 22ozs or more.

    This is a great ar-9 buffer. Have bought and used many of these on builds. A must have.

    No issues with it, and now no need for a buffer spacer

    I think it will be a very solid buffer, I haven’t used it yet.
