12ga to 7.62x39 Shotgun Adapter Text

7.62×39 Shotgun Adapters

(85 customer reviews)



Because of the many variations of 7.62*39 ammo, it is recommended that each type of ammo be tested using the methods that are typically employed with high-pressure ammo. One way to accomplish this is by firing them out of a vise or something equivalent, remotely and using a string. In doing so, one should always shoot from a safe distance and always utilize eye protection. After the round is fired, examine the casing. If the primer is badly deformed or punctured, then it should not be used in the shotgun. If you do not have a compatible shotgun, you may return the product for a full refund.

Another note: Steel casing ammo tends to stick in the chamber, which may necessitate the use of a pocket knife, screwdriver or other prying mechanism to remove it.

Rifled with a 1:12 twist rate.

Rifled Dimensions:  6 Grooves.   Bore .300  / Groove .310

Please Note:  Not all shotguns are the same!  While most shotgun are capable of handling high pressure rounds such as the. On the other hand some are not.   Therefore only use these rounds in shotguns that are capable.  For example, a shotgun with a SB1 or Sb2 reciever.  I recommend on any shotgun to test the first shot in a vice while out of harms way in addition  always wear eye and ear protection.  After that if you see that the primer punctured in the round discontinue using this round and use the less powerful round. Such as a 38 Special instead of the 357 Mag These high pressure rounds include: 45-70 gov., 357 Mag, 327 Shotgun Adapters , 44 Mag, 30-30 Win, 7.62×39 and 22 Hornet.  Please always be safe and aware.

    I’ve been putting off commenting until I can get to the range and test this thing but tbh its just too hot here. Mine did not come with a cutout for the extractor like in the instruction. Its ok, I can dremel one out later after I see if it works with my gun. Other then that the shipping was fast and quality is excellent as always. Thanks!

  14. Jimmy Braddy (verified owner)

    Great bunch !! They let me know that my item was available and in stock…..Thankyou !

  15. Daniel Keith (verified owner)

    Very good quality. Fits perfectly in my NEF SB2 Handi Rifle/shotgun combo gun (.223 and 12ga). I’m happy to have this adapter. I also have a 18″ Chaszel 45-70, 18″ 45 long colt, 11″ 12ga to .22 adapters.
    FWIW, NEF and H&R SB2 Handi rifles have alloy steel receivers. All other SB1 or otherwise are made of iron. And interestingly, the new Chinese made Stevens model 301 shotguns have Steel receivers. I have one of these also and it is surprisingly well made and I plan to test it as a platform for these barrel adapters too.

    Everything I have purchased from you is an excellent product and shipped to me promptly .Now if you could send me two 410 gauge to 22 magnum and two 410 gauge to 357 magnum along with two 12 gauge to 303 British and two 12 gauge to 7.62 x 54 R I would certainly gladly pay for custom orders. Thanks for the great product at fair prices.

    Have not chance to shoot it yet. I own 44lc and it is pleasure to shoot with regular and plus p loads.The finishing of the insert is high quality and the shipping was quick. I will buy again from Chaszel.

    Has anyone used the 7.62 X 39 in a Nomad .12 gauge shotgun ? Just wondering if this ATI shotgun can handle the pressure ???

  25. Brian M. (verified owner)

    I ordered Two 12 guage to 7.62×39 shotgun adapters. I’m really happy with them. They arrived quickly and I’m running one in my Acme single shot 12 Guage shotgun, fluid steel barrel from 1905. There was no case sticking or difficultly extracting the spent case, it was vary accurate as I was able to nail a target 75 yards out with no issue. I also order a two 12 Guage to 9mm adapters a while back and they also had the same awesome results. I’m really happy with them as they pressed some of my older antique shotguns Into becoming decent survival rifles.

    P.s. I run the pistol caliber adapters in my Damascus steel shotguns and the rifle adapters in my fluid steel barrels with no issues! The 7.62×39 is a bit much for a Damascus steel barrel. The pressure curve can split the soldered rips on long barreled shotguns, but runs fine in a coach gun length side by side Damascus barrel shotgun, you may need to shorten the firing pins on shotguns made before 1910

    I highly recommend Chaszle chamber adapters for anyone who wants to get a bit more use out of their break action shotguns.
    The applications are endless and I’ll purchasing more adapters in the future.

  26. George (verified owner)

    Great product. Fast shipping.

  27. Jeff G. (verified owner)

    I’ve bought over 20 inserts in these calibers 7.62 x 39, 30-30, 38/357, 45acp, 45/410, 380, 9mm, 44 magnum, and happy with how they all have done. I know everyone else must be happy with what they are buying because now every time I want more there are none to be sold.

  28. Christopher (verified owner)

    Worked exactly as advertised. Using a single bead sight, my initial impacts were similar to shotgun slugs– a foot low at 25 yards. But compensating is quite possible. No problems with bulged primers. And the ammo is a fraction the cost of 12-ga. slugs!

  29. Erik (verified owner)

    Quality is good! Have only tested a few rounds but accuracy at 50 yds out of my 12 gauge O/U was about 1-3/4″ for 3-shot groups.

  30. Mikheil (verified owner)

    Adapter works ok, hard to extract the fired shell. Would be great to have an extraction feature or some basic tool supplied at the purchase. Using the ram rod and some screw drivers right now. Some steel shells get stuck pretty hard.

  31. Daniel (verified owner)

    Excellent service and quality of products but I wish more products where available at your web page

  32. Howard W. (verified owner)

    I’m very pleased with the Adapters, they worked great in my off brand bubble barrel. I strongly recommend that you only use brass case AMMO because with the steel case I almost needed a ramrod to remove it .

  33. Jessica G. (verified owner)

    Great workmanship, excellent product, outstanding customer service

  34. James (verified owner)

    Just what I was looking for

  35. Ronnie S. (verified owner)

    Great craftsmanship and well built . I have tried to fire two Geco brass casing both have strikes on the primers. Either round discharge. I have fired two Tulammo steel casing rounds . Both the primers blow a hole through it and one steel case missed fire with primer strike no discharge. I’m using the adaptor in a Fedarm / Berika arms single shot 12 gauge . I think its made in Turkey.

    It came fast and the finish is nice. I like it

    Good quality machine work and finish, I got the 7.62×39 in 18 in. Do not use this in anything other than a quality steel reciever shotgun, accuracy is well within minute of Deer at 100 yards (about 3 inches)…cheap Russian and Chinese steel case ammo expands to tightly fit the chamber and requires a drift and mallet to remove, I have had no problems with brass cased ammo removal. I like it and the concept of multiple calibers from one firearm…can’t wait for 9mm to come avalible.

  39. Kevin S. (verified owner)

    This barrel insert was a pleasant surprise. It shoots with better accuracy than any AK-platform rifle I’ve fired. The workmanship is excellent. I expect this insert to serve me well for the rest of my life.

    I am very pleased with this adapter! I have bought several others and I plan to buy more in various calibers! I have also told and shown others about these adapters and they were impressed!

  46. Michael (verified owner)

    I have been waiting for nearly a year to snag one of these in 7.62x 39. Finally ordered one and it arrived within a week.Works great in NEF shotgun . I have had zero issues with brass cased factory cartridges, altho as warned, steel cased ammo is slightly harder to eject without prying it out. Hoping the 22wmr restocks soon.

  47. Anonymous (verified owner)

    Very good quality.And very accurate will definitely be purchasing more barrel inserts.

  51. frank v. (verified owner)

    have not fired it yet, but service was great, fitted it to two guns and checked for spec’s, all looks good! I’ve bought adapter’s that shell did not seat correctly in chamber causing trouble with gun lock-up! test fire will complete the review. machine work and finished product look great!

    Work excellent in my 12 ga slug gun

  55. Robert (verified owner)

    Surprised at the accuracy out to 100yd and below. All maintained kill zone accuracy consistently shot after shot. Much more than a pinging toy, would have no worries with a buck out to fifty yards.

  56. Anonymous (verified owner)

    This is the highest quality shotgun barrel insert available. I shot at an outdoor 100 yard range and this insert will hit a 8 inch pie pan using a Mossy Silver Reserve with bead sight consistently. This will be my deer gun for this year.

  57. Donald S. (verified owner)

    This is my 4th barrel insert that I get from Chaszel. I am more than satisfied with their barrel inserts. Great product!

  58. Jack L. (verified owner)

    Due to covid I had to wait on the list for several months…it was worth the wait…I’ve gotten back on the list for another one…different gauge very happy with the quality of my product and it’s a helluva lot cheaper than purchasing another long gun to put if a safe that’s already full…the only way they could have made it better was to gold plate it haha…very happy in lower Alabama

  63. Richard Brown (verified owner)

    Worked great with my Rossi Overland Coach gun. Would not fire the rounds in my Midland Arms Backpack (even though the primer hits looked good). My old Eastern Arms resulted in punctured primers. My Hatfield SGL also punctured the primers. This was using cheap Tul ammo steel cased. Love the product. Well made.

  64. Daniel S. (verified owner)

    This is a great adapter. Beats buying and registering a whole new rifle/shotgun. Shot extremely well with Fiocchi brass case ammo. I created some reduced loads to check chamber pressure and safety, worked my way up to max load with no issues in my Baikal M-18 12 gauge. I’m sure I could take down a deer inside of 100 yards if I wanted/needed to. I’m hoping for the 20 gauge to become available soon. I’m very pleased and impressed with this product. Thanks!

    Clocked with the writing at 3:00 this adapter does great. Steel case ammo was sticky as it took a screwdriver to get the empty out. Not so with Hornady Black brass case. They shot straight and the empty came out easily.

  71. William Thomas (verified owner)

    This product is incredible! It is beautiful in appearance and it fits in my shotgun like a glove. My initial rating is five stars without reservation.

  72. Lawrence V. (verified owner)

    I haven’t had the chance to use this adaptor yet, but it looks and feels just the same quality as other of their adaptors that I have used which were great. Their shipping was fast. I’ve used 2 or three other brands of shotgun adaptors and these are the best I’ve found.

  73. Gary (verified owner)

    While I’ve not had a chance to try it out, this is my second insert. Customer service is swift when I asked questions before purchase. This purchase arrived very quickly and physical exam shows the usual high quality.

  74. John Z. (verified owner)

    So far, all is good. I did have some problems getting spent casings out of the chambers, but that was with cheap TulAmmo stuff. Going back tomorrow with some good stuff. Beautifully made, quality adapters. Worth the price.

    Edited today: went back with some better quality ammo. Still having some problems getting the casings out, but seems a bit better. Maybe some break in will help. Only 60 rounds so far. Otherwise good.

  75. Arcy Swopes (verified owner)

    Great product,great delivery service.Would like to get more in the future.

    Great product for the price. Best company for the market. Shipping and handling was as advertised, very satisfied. Look forward to 22LR/22Mag being back in stock in 12Ga, so I can make a purchase. Hopefully production can begin to meet demand soon.

  82. Allen Cromwell (verified owner)

    Ive enjoyed all the adapters purchased from Chazels-they have all worked perfectly -my resent 7.62×39 adapter has also worked perfectly-my opinion-they are the best made adapters-Period.Buy them all-do yourself a favor.

  83. migue morales (verified owner)

    really an amazing item.

  84. Tony (verified owner)

    I bought this knowing the risk of potential damage to my gun and my Hatfield SGL is out of commission. The primer blew out, propelling the firing pin out of the gun at a very high rate. Use at your own risk! I have several other Chaszel handgun caliber inserts and the quality of their products has not changed, still top notch! I would recommend this but I don’t know what guns are ok with it, just NOT the Hatfield SGL.

  85. kenneth moores (verified owner)

    blown away by the fast shipping and the fact that this company listened and built this caliber , i shot 30 various lose 7.62×39 rounds outta this insert from my midland backpacker with zero problems, i truly think with this caliber you will sell alot to preppers n survivalist like myself that see the value in these inserts
