  • CALIFORNIA CUSTOMERS: Verify with your receiving FFL before you place the order!!! We are seeing some FFL's accept these and others are being extremely difficult and forcing customers to ship these rifles back to us. Verify with your FFL!

We are now opening up options for you to customize how much work you want us to perform on your rifle conversion, to offer a more flexible price point for those who are looking to save and perform some of these tasks themselves!

Rifles ordered without paint/refinishing can expect minor dings and paint/finish wear from machine work. Examples: Any cut surface will be bare (magwell, bayonet lug, front sight), mag catch is fitted to a variety of mags, minor paint chips may occur, and metal shavings will likely be present.

Each Optional service adds to base price:

  • All rifles will receive the magwell cut from single stack to double stack to accept standard AK mags
  • Conversion Option: Welded Muzzle Nut Removal - Cut weld on muzzle nut to reveal threads underneath
    • Not applicable to current batch of rifles
  • Conversion Option: Bayonet Lug Cut - mill bayonet lug to accept bayonet mounting
  • Conversion Option: Touch up paint on machined areas (adds working and drying time, may add up to +1 week to process order)
  • If you are looking for the DIY package that we have always offered in the past, choose all of these options!
  • NEW! Now offering the ability to UPGRADE to 90 degree gas block and 24mm front sight for only $199! If you select this option, slant brake or thread protector will not be included . We offer several US-made 24mm muzzle devices if one is needed HERE ***Use code UPGRADE24 to receive 20% off one muzzle device from that category when choosing to upgrade parts!!***
    • Can also choose to only upgrade gas block and keep a standard front sight, in case you want to maintain 14-1 or 1/2x28 threads.
    • When selecting the Upgrade, please do not choose bayonet lug or threading options, as those will be moot services when upgrading the parts.

Imported from Rogow Poland and manufactured by WBP the Jack Classic rifle offers rock solid features. WBP is a Polish based firearms firm supplying parts and firearms to Police, Military and Civilian shooters all over the globe. The Jack rifle is chambered in 5.56/.223 semi auto. We ran it successfully with 5 different 5.56 mags, so we can say it works with a wide variety of 5.56 mags.

These are beautiful rifles with Old School styling and look like an AK should look with gorgeous laminate stock set and deep rich black metal finish. The barrels are made by WBP in house, from 4150 steel and finished with black nitride. The rifle sports factory serial numbers on most major parts and the Polish Eagle on the left side of the sight block for added collectability & resale value. If you are looking for an AK rifle with Old School style and quality this may be the perfect rifle!

The WBP Jack is a result of input and requests from customers that loved the WBP Fox series but wanted a model with a standard AKM rear stock trunnion. The FOX rifle series offered the Beryl trunnion system allowing the shooter to install the Beryl Optic Rail. The FOX rifle has become a favorite for Kalashnikov enthusiasts and is one of the benchmarks that other AKs are gauged against. The roll out of new WBP models has been slow as they have wanted to focus on quality over quantity of their product but they are now up to 10 different models being produced, all with the same classic features and quality you've come to expect! The WBP Team will continue to listen to input from their customers and you can expect new and exciting WBP firearms and accessories in the future.

    Very nice gun. Fairly quick shipping. Had no problem hitting a 12"X12" steel target at 200 yards right out of the box. Pay the 25.00 to remove the muzzle cap. I'm no stranger to grinding them off but I had trouble with this one. I did pay for the bayonet cut and it works and looks great.Ended up putting a galil style folding stock and a SRS handguard from Bonesteel that looks great.

    I live in a communist state. New Yorkistan. Purchased for easiest to make compliant. Riveting looks perfect, everything was aligned as it should be. Shot 10 rounds through it at my targets a d has a solid go of it at about 45+ yards and hot the small ar steel plate with no problems. Will finish it to resemble a russian saiga until I get home to Tennessee. Cool, full on import. Not sure how long this will happen in the current situation. I am completely satasified

    Magazine release got cut by WBP fox

    Posted by RusBoi on Nov 26th 2023

    I was so excited when first time buying a Jack 55.6 DIYto do my zenitco project on it . Overall, the gun looks fine and beauty. But one thing I give this 4 stars because I don't know why they cut a small tip inside of mag release to make it all the way down to trigger guard that you will see in their pictures. It very hard to release the mag out and I had to hold the mag release 85-88 degree to release the magazine or it still stuck the feed lips inside if I can't do it . To resolve it, I had to cut a mini metal spacer with liquid glue to make mag release right at 85 degree position. Please fix it WBP :(.
