Faxon Announces ARAK-21 7.62×39 Kits

Faxon Firearms, maker of the ARAK-21 multicaliber rifle, have announced the introduction of 7.62×39 caliber conversion kits for their flagship firearm:

Faxon Firearms Adds the 7.62×39 Kit to the ARAK-21 Platform

Cincinnati, OH (Feb. 2015) Faxon Firearms, manufacturer of the innovative ARAK platform, is proud to announce the addition of the 7.62×39 Russian caliber to its offerings for the ARAK-21.

This addition will allow the user the added advantage of a larger caliber round and less expensive ammunition for more range time. This system makes the ARAK-21 platform one of the most versatile platforms on the market, allowing the user to have the potential to have three rifles in one (5.56, 300blk and now 7.62×39). The 7.62×39 caliber will be available for order in standard ARAK-21 upper receivers, complete XRS rifles, and as a stand-alone kit for existing ARAK-21s. Kits will be available in 12.5” and 16” medium profile barrels.

Current ARAK-21 users/owners can simply purchase the 7.62×39 kit as an addition to their current rifle upper. The 7.62×39 caliber kit comes with an interchangeable bolt, firing pin and barrel, all designed to work interchangeably with the current ARAK-21 upper receivers and XRS rifles.

Rather than modify existing components, Faxon took detailed time and testing to create a robust set of solutions that solve many of the issues of the cartridge that plague other conversions,” said Nathan Schueth, Director of Operations & Sales. “We lowered and widened the feed ramps to ensure consistent chambering, increased the bolt diameter to handle bolt thrust, and supply a new firing pin that matches the depth and width of the venerable AK to ensure consistent ignition.”

We set out to design a platform based rifle that takes the best of the AR and the best of the AK and combine them into one fantastic rifle with cross caliber capabilities,” says Bob Faxon, President and Founder of Faxon Firearms. “With the edition of the 7.62×39, we are expanding the capabilities for each user of the ARAK-21. This option further expands his or her platform and opens up many new shooting options.”

The ARAK-21 7.62×39 Kit has and MSRP of $499 and can be purchased at www.faxonfirearms.com or through Faxon’s dealer network. MSRP for single barrel upper receivers is $1199 and multiple caliber kits that include 7.62×39 will add $99 for the bolt and firing pin. 7.62×39-equipped ARAKs and kits will start shipping late February.

One of the biggest complaints about the product launches of other multi-caliber platforms has been the lack of conversion kits available for them. Faxon seems intent on providing its customers with caliber options for their rifles, reinforcing the “multicaliber” nature of the ARAK-21.

I got a chance to fire the 7.62×39 ARAK-21 at the Faxon Firearms event in Las Vegas. I didn’t have any problems with it in that caliber, though recoil was noticeably more stout than the 5.56mm variant – which I expected.

    So I can buy one of these uppers and plop it into my AR15 lower?

  • MPWS

    Mr. F. is slick businessman who seem to know every detail of his trade. On personal side my credence of him grows while he does not wear usual ‘professional’ smile; his style is more of substance based. As far as his product, it is not as easy take. First question: why to combine two outdated systems? Why not to come up with brand new and independent one? Are you telling me, it is not possible? I do not believe that. But, in common sense world, the concept is sound enough as is.

    As far as construction of receiver and means leading to interchangeability: it’s relatively cumbersome due to many fasteners (how do you assure they are all equally torqued and do not come loose?). There should be as few fasteners on firearm as possible. Next item is the fact (by his own admission) huge amount of machining increasing cost – this is no good – look at B-T design in comparison (extrusion). This was evidently designed by someone not from the field; albeit by a creative person. So at the end, it may never be considered by military (not to worry Colt). But Mr. F. does not make any mention of military as his product is making its way into enthusiast’s market. Good for him and all the best!

    I’d find it interesting if it didn’t use that magazine. So many companies have been down this road already.

    • Shifty

      I’d be interested in seeing if this upper can be mated to a CMMG Mk-47 Mutant lower. A long stroke gas piston AR that takes AK mags.

      • No, it cannot mate to a Mutant lower.

        • marathag

          Colt LE901?

          • That’s a better question. Maybe?

          • Also proprietary. The only two lowers that are not are the MGI and the MMAR-47. Both require substantial modification to the receiver and bolt carrier to work.

          • I know the LE 901 has a proprietary lower, but I was under the impression it was compatible with AR-15 uppers (and thus maybe the ARAK?).

        • An Interested Person

          Why can`t it mate to a Mutant?

          • Nothing can mate to a Mutant lower except a Mutant upper. It’s a proprietary length designed around AK magazines.

          • Rusty Shackleford

            So, both the CMMG Mutant and the RRA LAR47 use proprietary uppers?

          • Yes.

  • Green Hell

    So… This is basicly an AKARAK?

  • Dear Nathan at Faxon:

    You told me you would send me a full auto upper to test for a TFBTV segment. Can you pretty please send it to me so I can saturate the earth with lead delivered by Faxon 🙂

  • Don Ward

    Doesn’t the scope also need a yellow 7.62X39 rubberband?

    • Now that would just be stupid. 😉

    • Worth noting that at the shoot they put on, it would have been really bad if they hadn’t had those rubber bands. As it was, at one point IIRC a 7.62×39 magazine got loaded into a .300 Blackout gun. Good thing it wouldn’t chamber!

      The two best Faxon products, in my opinion, are the rubber bands and the barrel ID bands, for that reason.

  • KT

    Stupendous! Now make a conversion kit in 6.8 SPC Spec II, please.

    • Sorry!

      6.5 Grendel is up next. We like it since it uses the same 7.62×39 bolt!

      • KT

        Ugh. Compatible bolt patterns aside, why are you going with 6.5 Grendel? It’s a competent cartridge, but it’s not as common as 6.8 and it’s more expensive to reload. Looking on Midway (not the end all be all) there are sixteen options for 6.8 SPC ammo. 6.5 Grendel? Five.

        Bob told me when I bought my ARAK two years ago that 6.8 SPC would be “in the works” once production was stable.

        Tired of waiting. Time to look elsewhere.

        • We are sorry to hear of your disappointment.

          We have plans for many new calibers and 6.8 is among them. Each time they require a new bolt, its a significant engineering effort to ensure they are functional to our standards and more importantly, not able to chamber rounds from other calibers.

          6.5 is an easy next step, especially with it sharing tooling with 6.5 Creedmoor for the .308.

          We hope we can serve you in the future!

        • Jee whiz, guy, new bolt specifications don’t grow on trees!

        • Lujan

          I’m tired of waiting for a better all around cartridge as well, in something new & different. Even in ARs your choices are limited. But I wouldn’t wait for the 6.8 over the 6.5 Grendel. They’re both great at short to medium engagements, but at longer ranges 6.5 clearly is superior. As far as it being more common, Russian suppliers are about to make 6.5 Grendel more common. Besides you can reform 7.62 x39 brass to form 6.5 Grendel. One writer on his experiences with 6.8 hunting said he found himself holding his fire beyond 300 yards, something like that, because he wasn’t as confident in his ability with it. And that was from a bolt gun. I’ll post the reference if you’d like.

  • the_duck

    How long should I wait until I buy one if these before all major issues and refinements to weight and function are in a really good place? I don’t like to buy the first of anything, and there has been some issues with the first batches that were remedied.

    Maybe in a few years, and hopefully they’ll find some production efficiencies so that overall price goes down too.

    • Refinements are in place. We’ve had two years to work out the bugs and the last year plus of uppers have been great!

  • FourString

    Will this work with a lower that accepts AK magazines? 😀

    • It cannot. All lowers, except MGI and the MMAR-47 are not compatible with an AR-pattern upper. Those that are require significant modification to the upper receiver and bolt carrier to function.

      The AK magazine is significantly wider than the standard AR magazine. Combined with the high feed lips, its a difficult magazine to design for compatibility.

    Mr. Nathan,

    It’s very refreshing with how open and responsive you, and of course Faxon Firearms, have been with the firearms community about your product. I’ve noticed your contributions to other firearms sites and they’re always informative. I do have a question regarding availability, I work for a gun store in northern GA and have noticed that Faxon products are not available through the distributors we use, are there any distributors you are currently using? If not currently are there any plans to do so in the future? Thank you very much for your time.

    • We are very happy to hear the feedback!

      We currently work directly with our dealer network, not through distributors. We feel that you will get the best product, service, and price by working direct with the manufacturer. Please send us an e-mail to get set up! Nathan@faxonfirearms.com

      • Matthew

        Thank you for your reply! I’ll have to run it by my boss when I see him and I’ll see if I can spark his interest. I hope you’ll hear from us soon!

  • Look, it’s Nathan!
