    Kak 9mm bolt heavy tungsten weight.

    Posted by Brian L on February 16, 2026

    The weight is a perfect addition to the GRS. It fits the bolt nearly perfect, 1/4" pin supplied if you need it. I had to shorten it a few mm so that it was flush with the end of the bolts rear face. (Grinder with diamond wheel) just SSd it and it runs like a champ.

    9MM CARRIER WEIGHT EXTRA HEAVY

    Posted by PHIL HENNE on February 16, 2026

    installed easily and was much heavier and denser than original part which should slow the dwell time and reduce gas significantly as designed

    9mm bolt weight

    This fit perfectly in my BCA 9mm bolt, I'll try it with a 9.5 oz K-spec buffer and see what happens

    Smoothed the recoil pulse

    Posted by Hugh Mannisto on June 5, 2025

    I added this weight to the bolt of my AR9. Even though it's only a small addition of weight, it made a noticeable improvement in the recoil pulse of my carbine. It was shipped super fast too!

    Confirmed fit PSA ARV FailZero

    Posted by Dan on June 3, 2025

    This piece is a confirmed fit in both the PSA ARV and FailZero 9mm bolts. The standard weight for both is 2.5oz, sophisticated piece adds 2oz of weight. Easily swappable to increase reciprocating mass of the bolt, which is nice in situations where there aren't many options for buffer modification (SB HBPDW, Maxim defense). Overall very pleased.

    Extra Heavy Carrier Weight

    Posted by Carlos Patterson on May 22, 2025

    I had a BCG that had a normal carrier weight that actually would need to be cut down to allow it to work with a Super Safety. I purchased this one and installed in place of the old weight and no cutting required. Plus the added weight should diminish the possibility of carrier bounce.

    22ozs or More...

    Posted by A. Magno on February 10, 2025

    I used this in conjunction with KAK's 8oz PCC extended buffer to increase the weight of my DOE's action to 24.4ozs. By doing this it mitigates any bolt bounce and out of battery detonations which is common with AR9s with lighter actions. Not only that, this helps with recoil impulse. So remember folks, the rule of thumb is 22ozs or more for the combined weight of your bolt and buffer. The more the merrier. Good luck.
