5.56 WBP Polish AK Bolt *New Production - Spring-Loaded*
Brand : WBP
- SKU:
- 20865
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 5.56 mil spec bolt? These bolts are fully machined from forged steel just like the original military soviet era produced bolts. Unlike any other new production AK bolts currently being sold WBP checks these bolts for 58 proper dimensions using the Zeiss CMM.
Includes 1 complete full/semi auto bolt, includes firing pin and extractor.
FAQ:
-This bolt has a thicker stem compared to the FB Radom bolt which is a true 74 spec thin stem. However it is thinner than a standard 47 AKM bolt. See comparsion photo for details.
-We recommend using the WBP 5.56 bolt carrier for correct compatibility. A standard 74 carrier will be too small, and 47 carrier too large.
-We recommend using the WBP 5.56 trunnion for ease of building. Others may work but we cannot guarantee part compatibility with different trunnions.
-We offer a bundle pack of all core 5.56 parts 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

Fits a Yugo M85 bulged front trunnion!
It's not included in the product description, but here's the bottom line up front:
- WILL fit a Yugo M85/ZPAP85 (5.56x45) front trunnion*
- Must be paired with a WBP bolt carrier
Honestly pretty good experience from AoA as always. I've been a longtime customer; for good reason. They've always had exactly what I needed in terms of kits or niche parts. I emailed AoA in order to find out if the specs of this bolt would work for what I needed (Yugo M85 pistol rebuilt). They responded same day to answer my questions about the specs. It's VERY difficult to find a Yugo M85 replacement bolt, but due to this bolt having AKM specs, this bolt works excellently. AK-74, Beryl/Archer 5.56, most other 5.56 bolts do not work with a Yugo M85 as the locking /cam lugs are a different spec. This bolt will work with the Yugo M85 bulged front trunnion; however, it may not fit in an M85 bolt carrier (don't know, don't have one to try it out or take measurements).
* = As always, when building ensure your parts are mated properly and meet head-spacing requirements. This bolt works for my M85 build but I cannot guarantee it will work with yours. Ensure your parts are properly head-spaced and always check with a certified gunsmith if you are unsure! -
Even though it's for a 5.56 it did not fit properly in the AK I have it got caught up in the grooves when you tried to cycle the Bolt
The firing pin seem to fit my old Bolt so I am going to try that instead of replacing the whole thing

This is a quality piece. When comparing to other import Ak bolts it is like night and day. The machine work on this bolt is very nice and consistent.
