WBP Polish AK47 Bolt Carrier 7.62x39 *Brand new hammer forged production made in Poland* For STAMPED Receivers

Best smooth and awesome Carrier from Poland

This a very nice bolt carrier to complete your build or to replace your old one.

Purchased w/bolt. Fits nicely in my Riley receiver build!

Carrier has some noticeable tooling marks along the top, which made me settle on a 4 star instead of a 5 star rating. Polished it per the Dan Daman YouTube vid, which seemed to help smooth out the action slightly. Basically, I ordered two MDC-47 UCR AKs and should have opted for the KNS piston upgrade but didn't. Not wanting to modify my original bolt carriers, I ordered some of these to install KNS AKM Small Bore (AGP-A-10S) pistons. Using the bolts from my MDC-47s, they easily passed two brands of no-go gauges. With the Zinc coating it was challenging to identify and mark the center of the retaining rivet heads in order to use the nail setter punch and start drilling, but patience is your friend. Went from 1/16" to 3/32" to 1/8" drill bits on the retaining rivet heads to ensure they were drilled out properly. Using a drill press helped a lot. After that, punching out the rivets with a 3/32" punch was easy and the pistons unscrewed off the bolt carriers by hand. Installing the KNS piston is simple after that. From fully closed, opening up the KNS piston 20-23 clicks was all I needed match a RD-703's recoil impulse, which had the tunable RD gas block set from the factory for unsuppressed shooting. Brass ejection was 5-10 feet depending on ammo type. Went with the small bore KNS pistons to avoid short stroking issues, since I'm using these unsuppressed. No malfunctions with a couple of hundred rounds on a hot day, but will need to test it on a cold day as well to ensure the adjustable gas setting is reliable.

Very Nice

High quality bolt carrier!

The WBP Polish hammer forged 7.62x39 bolt carrier for stamped receiver from AoA is brand new. As all products coming from WBP of Poland, finish and workmanship is excellent. In the 1990's,I used to own a
Chinese AKMS underfolder with a spike bayonet made by Shen Yang armory (not Polytech or Norinco) and the tooling marks were all over the components. Workmanship and quality seems crude. Not with this WBP bolt carrier, every thing is smooth and precisely cut even in the recesses where the bolt head and lugs turn and rests. Material seems stainless steel with a matte satin finish. I tested fit with a RecreatorBlank receiver and it was perfect, glided through the rails with no binding. If you're for a Polish build, this is a must have. Mate it with a WBP bolt (AoA also carries them) and you're set for an authentic Polish stamped AKMS/47. As usual, these items go fast so get them when they're in stock or you'll have to wait ages for them to be available again.

No clue why anyone would even have to consider reading a review on any real part from Poland. If you're reading this and haven't bought any of these yet, or any other WDP Polish part Arms of America sells, you're an idiot.

Had to make a couple of calls to customer service, don’t know how great it was to get right through to a knowledgeable person, without going through a dozen menu promps

Great quality I highly recommend

Bolt carrier group I have built one AK with the same bolt carrier performed flawlessly It is very smooth in battery. Bought another one polishes up very nicely. If you have any sticking it’s not the bolt carrier usually it’s the selector is located maybe a little too high in your build but is a easy fix by filing the inside of your safety selector . If you use a jig you will not have a problem.

Fits snug. Works like expected. Would buy again
