    9mm bolt weight

    Posted by Miles McGonigle on June 5, 2025

    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.

    Bolt Weight

    Posted by Eric Devilbiss on November 16, 2023

    I used this on my Foxtrot Mike FM9 bolt. It didn't fit, but I saw on blowback9.com that you could make a sleeve for it. That worked great and my bolt went from 14.1oz to16.7oz. Adding the extra weight really helps slow down the bolt and bring down the felt recoil. I highly recommend.

    Great way to “mass up” your blowback bolt.

    Posted by Chris on September 14, 2023

    The first one I ordered came with the hole for the roll pin drilled off-center and it couldn’t be used. I contacted KAK and they sent me a replacement ASAP. I wanted to use this in conjunction with a hydraulic buffer, so that my combined bolt and buffer weight would fall within 22-24 oz range.

    9mm Tungsten weight

    Posted by Brian Pollard on June 11, 2023

    love this weight. I have added 5 or 6 now to all various kinds of 9mm bolts. Definitely gets the weight up for blow back PCC.
