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.

-We recommend using this WBP 5.56 bolt carrier for correct compatibility. A standard 74 carrier will be too small, and 47 carrier too large.

-We recommend using this WBP 5.56 trunnion for ease of building. Others may work but we cannot guarantee part compatibility with different trunnions.

-While we do list these spare parts separate from kits, if this bundle is out of stock then one or more of the allotted spare parts may be sold out. Our full 5.56 kits can be found 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
