Hard Cast Bolt Weights
(patent pending)
Forced reset triggers and super safeties are all the rage, but they require that the bolt weight be removed or modified to function in a blowback PCC. Removal is not a good option due to the loss in bolt weight, and modification may be beyond the capabilities of some shooters. Our hard cast bolt weight is sized to accommodate these devices without modification, and you also gain an additional 1/4 ounce as a bonus.
Pre-Drilled
If you have a typical PCC bolt such as the one shown here, we offer hard cast bolt weights that have been pre-drilled for the spring pin.
Un-Drilled
If you have a blowback PCC bolt of a different variety than that shown, you can order a bolt weight that has not been drilled for the spring pin.
This bolt weight came out of a Fail Zero 9mm PCC bolt and is typical of bolts in that configuration, including; KVP, Faxon, Expo Arms, Odin, BAD, Toolcraft, RCA, along with many others. It hits the scale at 2.45 ounces.
In the blowback PCC world, it seems that every fraction of an ounce is beneficial, and an additional 1/4 ounce can't hurt. After boring the hole for the spring pin, the hard cast bolt weight comes in at 2.70 ounces, while providing the correct length for function of FRS and SS devices.
We have become aware of certain bolts sold by KAK and RTB that have a smaller than typical bolt weight diameter. These are easily identified by the "tuning fork" shape of the bolt weight. If you have a KAK bolt, please measure the diameter of the original bolt weight before ordering. We do not currently have a mold that will drop a .614" diameter hard cast bolt weight, but if there is enough interest we might consider it.
