100% Brand new Polish production AKM-47 Parts kit utilizing the original Military forged trunnion. MFG in Rogow, Poland by WBP These parts kits feature a 100% fully machined bolt & bolt carrier fully heat treated w/ finish. Unlike any other new production AK bolts currently being sold, WBP checks these bolts for 58 proper dimensions using the Zeiss CMM. Built to serve both civilian and law enforcement needs these parts kits have the ability to function in semi auto only or select fire/full auto if necessary. We do not include the 3rd axis pin or fire control parts in this package.

This parts kit includes everything needed for a standard spec AKM build, minus furniture, receiver, and trigger parts which we offer. You will also need rivets to complete the assembly.

You will want to purchase the following to complete this (we offer all of these parts)
-US Semi Auto trigger group
-Rivets for assembly
-Furniture such as buttstock is not included but this kit will accept all popular AK stocks such as Magpul, Tapco, and most surplus stocks.

These parts kits survived extensive torture testing from AKOU

Your kit is 100% head-spaced correct out of the box. We perform a series of checks across several team members prior to every order going out.
If you have concerns, you must check headspace before changing anything about the headspaced assembly. If you have questions, please take pictures, and/or video, and reach out to us.
Once the barrel is removed, or any alteration has been made to the populated barrel, at that point the customer or builder becomes responsible for a proper build.
AOA cannot take responsibility for a headspaced assembly once alterations have been made to our gunsmith's work.
Removing the barrel and reinstalling it may result in head-space loosening or tightening of your pre-head spaced kit.
Recheck head-space after you are done riveting your trunnion into your receiver and reinstall the barrel, and ensure it is good before pressing the barrel pin.
Once all built, please clean your firearm before firing to make sure your new firearm is clear of assembly or shipping debris,
Thank you again.

    kit was in excellent condition and came with all the parts promised. I checked the head-spacing and it was perfect, solid lock up! I may get another if they're available again.

    Just got mine built. Easy build, no issues with the parts kit at all. Mine was new parts, no markings on the trunnion, just WPB and the Polish eagle on the rear sight block. Everything pressed together smooth, no binding. Put 300 rounds through the gun first trip out to proof the build. Rounds feed good, ejection was consistent 20’ away in the same spot. Well worth the money, half the cost of a factory built gun.

    Really nice kit, ready to build. All barrel parts were lined up strait, bolt is correctly head spaced, pins nicely drilled. Components are nicely machined and are of the same finish. The trunnion does not have a serial number but the bolt does. So I think these were originally virgin parts that were assembled by AoA. Very pleased with this 5.56 kit.
