NEW 5.45 offering from WBP!!

These are produced by a modernized arms factory in Poland that focuses specifically on high end Military grade parts. Looking for a true brand new 5.45x39 mil spec bolt? These bolts are fully machined from forged steel just like the original military soviet era produced bolts. Thanks to modern technology the specs are even better!

These 5.45 bolts contain a spring-loaded firing pin.

Unlike any other new production AK bolts currently being sold WBP checks these bolts for 58 proper dimensions using the Zeiss CMM

-This bolt has a thicker stem compared to a true 74 spec thin stem. However it is thinner than a standard 47 AKM bolt.  Due to this, we recommend using the WBP 5.45 bolt carrier for correct compatibility. A standard 74 carrier will be too small, and 47 carrier too large.

-We recommend using the WBP 5.45 trunnion when using the WBP 5.45 bolt and carrier for ease of building. Others may work but we cannot guarantee part compatibility with different trunnions.

-We offer a bundle pack of all core 5.45 pa
rts here

-These parts are meant to be built in any 74 style 5.56/5.45 receiver

* Anytime you install a new bolt into a firearm it is always a good idea to check headspace before operating or allow a qualified gunsmith to check it. It is possible this bolt will require minor fitting to one of the lugs before it will lock into battery depending on the rifle. When these rifles are built the bolt lug is typically hand fitted to each rifle at the factory and WBP has removed a small amount from the necessary bolt lug so it will work with most rifles without adjustment. But it is still possible you will need to do some additional fitment
