357 Shotgun Adapters for 12 Gauge Shotguns

357 Shotgun Adapters Allow a 12 Gauge Break Action Shotgun to use 357 Magnum in addition to 38 Special Ammo.

For 3″ as well as 2.75″ Chambers

Compatible with Break Action single as well as double barrel shotgun.


Rifled:  with a 1:18 twist rate for the 11″ and 18″

1:12 twist rate for 2 3/4″ and 6″


357 Shotgun Adapters Rifled dimensions are .355″/.349″ with 6 lands and .125″ wide.


Black Oxide coating as a result provides notably better corrosion protection (for maximum corrosion protection keep a thin coat of oil on the insert)


Please Note:  Not all shotguns are the same!  While the majority of them are capable of handling high pressure rounds, some are NOT.  Only use these rounds in shotguns that are compatible.  I recommend on any shotgun to test the first shot in a vice while out of harms way and to always wear eye and ear protection.  If after testing you see the primer punctured in the round discontinue using this round and use a less powerful round. These high pressure rounds include: 45-70 gov., 357 Mag Shotgun Adapters, 327 Federal, 44 Mag, and 22 Hornet.  Please always be safe and aware.
Thank you for reading.

What are Shotgun Adapters?

Shotgun Adapters frequently called Chamber Reducers or Shotgun Barrel Inserts. Our shotgun adapters allow you to use other types of ammunition in a Break Action Shotgun. Including double barrel and over and under double barrels in addition to the popular single barrel break action. We offer several different versions to suit your preference in ammunition, as well as length. 12 and 20 Gauge shotgun adapters are our most popular adapters followed closely by the 410. 16 Gauge is something we plan on expanding in the future.


357 Shotgun Adapters are a High Pressure round

However, not all shotguns are capable of handling all of the shotgun adapters we offer. Low-pressure rounds work in any shotgun, whereas high-pressure rounds can cause problems in some shotguns. The problem is when the firing pin punctures the primer. This event causes the gases to escape and possibly damage the firing pin. All adapters chambered for high-pressure rounds have red text on the website, signifying that is is a high-pressure round. These adapters also include a pamphlet with more information about this concept. In addition These Shotgun Adapters also have a Low-Preasure round alternative.


357 Shotgun Adapters

Most of our shotgun adapters come in different lengths to suit your needs. Some like the secure storage and portably of Shell length adapters. Whereas some are looking to get the most fps (feet per second) or accuracy out of their adapter. Black Oxide has become our standard finish. We can offer unfinished adapters during our production if you have requested one.

FPS (Feet Per Second)

As a general rule, the longer the adapter, the more FPS it produces. However, with low-pressure rounds such as the 45 colt, the fps difference is minimal once past the 11″ length. If you are interested, here is an excellent website that gives a good idea of fps per inch BBTI. All of our shotgun adapters are entirely made in the United States and are an affordable addition to your break action shotgun. Thank you for you interest in our Shotgun Adapters or Chamber Reducers. We are working to make more adapters for more calibers, so you can sign up to be notified here
The video below gives a brief demonstration of how they work.

    Excellent ,much post purchase satisfaction!

  3. Ezekiel E. (verified owner)

    Just got this in, been wanting one for years! Slipped it into my NEF shotgun and nabbed a doe at 70 yards first day of the season! Can’t wait to get the 45-70!

  4. Verified Buyer (verified owner)

    Excellent product, wanted the 18 inch adapter for rifle like feel from my shotgun and that’s exactly what i got. Love it. Thanks a million.

  5. Verified Buyer (verified owner)

    I give a 4 and not a 5 because of 1 reason only. This shoots so well in my NEF 12 gauge that I REALLY want a 30-30 insert …but alas they are out of stock.
    However my 357/38SPL adapter is great and for hunting purposes is very accurate. I recommend 100%

  6. Joe M. (verified owner)

    Always good to do business with chazel. Great inserts at very good prices and excellent customer service and fast shipping

  7. carygoldsmith1 (verified owner)

    I ordered the 18 inch 357 adapter. Installed it in my new Yildiz 12 gauge I just purchased from Academy. I reload 38 special so this is perfect for me. Have a nice 357 rifle for under 300.00 ! What else to say? Thanks a million, quality, reasonable, perfect.

    Very pleased. The fit and finish are perfect. Well worth the investment.
    I’m going to see what it will take to to install a red dot on my old shotgun. Brings some of the fun back in to shooting.

  12. Joe C. (verified owner)

    1 Great looking piece.
    2 Fits like it was made for my shotgun. 3 I couldn’t believe the accuracy of this insert 1 1/2 inches at 50 yards.
    4 I am wondering what caliber next maybe 762×39?

  13. randy l. (verified owner)

  15. charles walter (verified owner)

    I’m taking this out to my range for sight in. I’ll use red dot optic to line up the bore with the bull, then I will index both the barrel & the insert so that I can reinstall insert & maintain accuracy. sound O.K.?

    Great product as always. Fast shipping,

  24. alex c. (verified owner)

    The pros. Super accurate. With a red dot I was making hits at close to 200 yards with no bullet drop. Velocity is quite high as well. I feel confident in taking a deer out to 200 yards or less.
    Cons. It took over a year to get. But I’m already waiting for a 44 mag insert

    Purchase experience was great as usual. I haven’t had a chance to use the barrel yet. If it’s anything like the others I’ve bought then I have no doubt that it’ll be a great barrel. I’ll be getting other calibers when I have then money.

    Purchased a 12ga to 357 mag / 38 sp – 6″ adapter. Had several questions before purchase that were answered quickly. Fit, finish and function of the adapter is top notch along with fast shipping. Spent casings remove easily. Will order more of different calibers as they come available.

  39. Joseph N. (verified owner)

    It function in my shotgun fine. Not sure if I should of bought longer barrel? Accuracy was lost dramaticly after 20yrds but could of been me. Over all happy with it.

  40. JASON DUNN (verified owner)

  59. Neil (verified owner)

    I researched many options and decided that the finish on these barrels looked supreme compared to the others out there. From the carefully tight bubble wrapped barrel in a sturdy tube delivered to my door, to the quality of and pride in the craftsmanship, it is as good as one could expect. The rifling inside the barrel is on par with any brand firearm I have bought. I got an 18′ 357 mag. barrel, filed down the rim at the bottom to prevent ejection and turned my Stevens 301 12g into a proper close range 50 yard rifle. I am considering the 9mm 11′ barrel next as 357mag. ammo is few compared to 9mm although the 9mm does not pack the punch for hunting, but is good for target plinking. You will not be disappointed.

  60. Toby Keffer (verified owner)

    First shot 20+ yards, dead center. Love it!

  61. David Lawrence (verified owner)

    Took longer than I would have like for the unit to become available but once ordered it arrived promptly and functions well. I have fired it enough to really evaluate the accuracy but much of that is just having a front bead sight to aim with. Very pleased with the inserts (2) that I’ve purchased.

    Works well, I only wish they had more inventory of other calibers as I’d like more of these 🙂 This makes my shotgun fun to shoot.

  67. James (verified owner)

    Excellent product. I waited two years to acquire mine last month. I have the .45 LC/.410 and now the .357 mag/.38 spl/.38 colt long/short adpters both 18″ long. This makes my Savage Model 24 combo .30-30 over 12 gauge even more adaptable. Great for single and double barrel 12 gauge break action shotguns especially those with rifle sights.

    I finally got to test out the 18-inch .357 liner in my NEF Handi 12. it only has a single bead front sight but was able to hit small water bottles at 25-30 yards consistently. Some of the noise was even masked by the extra 10 inches of shotgun barrel.
    Thank you Chaszel. Most awesome product. now I want to try other barrels.

  93. John Hammers (verified owner)

    Finally got a chance to try my 357 insert. It’s 18″ and very accurate. Much less expensive than a new lever action. I’m very pleased with the quality of this insert and will recommend them to my family and friends. Thanks Chaszel

  94. George (verified owner)

    These barrels make my fancy skatter guns very versatile. Expect 3 moa accuracy when you load to your gun and barrel likes. Don’t need expensive drillings when you own Chaszel adapters.

    Dang Chad! I’m happier than a kid in a candy shop. I just hope you can keep up with demand and maintain your top quality.
    Thanks a ton.

    Bought the 18″ 357 insert for my side-by-side coach. Fit and worked well. It did jam up the breech from opening once, but I consider it a great success. Currently making a dual barrel sight for a little more accuracy.

  108. Dickson Alley (verified owner)

    Let me start off by saying Chaszel barrel adapters are the finest I’ve ever owned. I own adapters from other companies, they don’t even come close to the quality of Chaszel barrels.
    I purchased the 45/70 & .357 12 ga 18” long adapters for my NEF single shot shotgun. I started shooting a steel target at 30 yds. Hits were at point of aim, moved target out to 45 yds still hit dead center. Took target out to 65 yds, still hit it. Considering my NEF has a 18” barrel and only a bead sight, I was amazed at the accuracy.
    Thanks Chaszel
    I can’t wait to try out a 22 lr adapter when ever their available.

  109. Norman Utter (verified owner)

  114. Charles (verified owner)

    I was impressed by the quality of the barrel. I stated with just the one o-ring. I was having trouble with adjusting the sights to the point of impact. I pulled the adapter out and turned it 90° and the point of impact shifted for the better, so THAT does have a bearing on impact. It did group well, only shot one 3 shot group (2 holes touching). Since AMMO is SCARCE and EXPENSIVE I will try again but with 3 o-rings and check again.

    So glad I bought it! Gave new life to an old H&R Topper that I have at my recreational property! That old shotgun can now be used to dispatch coyotes and varmints at a better distance than the shotgun. All the topper has for sights are a bead up front and a small notch centered on the receiver. I was still able to shoot 4″ groups at 50′ yards…

    Extremely accurate, can’t wait to get one in 30-30!!

  131. Al S. (verified owner)

    These things are very well made. They fit my CZ double barrel like a glove. They stop a few inches short of the muzzle and it really quiets them down. I’m going to remove some of the rim so the ejector slips past the barrel. This way the barrel will stay put when I open the barrel. Overall, I’m very pleased with them.

    I received my two 12 Gauge to 357 Magnum adapters in very good time from initial order. Upon opening the pack I could see that the quality in craftsmanship was exactly on par with other Chaszels review that I have read. Solid, Smooth and Clean machining of these adapters make them a must have for many years of trouble free use. I am looking forward to taking them to the firing range this weekend to test them out.

    Chaszel makes 1st class products! I am pleased! Waiting for the 20 gauge/30-30 adapter to be made now.

  167. Michael (verified owner)

    Better than expected. Easy to pull spent casings and accurate when timed consistently.

    Chaszel makes excellent shotgun barrel adaptors and I’ve shot and loved a couple that I bought earlier. I’m sure this will be the same.

    Great adaptor shoots good at 50 yards with just a bead sight

    As always a great product with an affordable price. I have bought several 9mm, 380, 38spl, 357, and the 45/410 inserts and happy with all of them and will by more in the future.

    Excellent products and service as always!!

    The machining work is spotless and very well finished, looking down the insert the rifling seems to be of good quality. The fit and finish are top notch and it fits snugly inside the 12 gauge barrel without rattling or getting stuck. Due to ammo shortages I have been unable to fire it with 357 mag ammo so I cannot speak to the accuracy.

    This is the second adapter I have purchased from you guys. It is awesome. I really enjoy being able to use my shotgun for things other than shotshells. I’m hitting 4 inch group at 50 yards and I’m not a good shot. Looking forward to getting one more to complete my collection. Anyone that is looking for more utility out of their shotgun needs to start buying these. You can’t beat the price or the quality. And they shipped fast. Keep up the great work.

    I’ve had a few adapters made by SL, but this .357 adapter is better. The black oxide finish makes it look like part of the gun, fits snug and stays put thanks to some partially inlaid rubber gaskets. It has a cut-out to allow the extractor to pop out without extracting the adapter, which I love, (but I can insert it upside down if I want it to extract every time.) Finally, it has two (count them, 2!) Finger nail recesses to pluck out spent casings. How luxurious. So now I’m certain to get the whole set, if they weren’t all out of stock of nearly everything…

    Seems to fit well in a TRADITION 12 Ga. folder. Not had a chance to shoot yet.

  179. David Rickard (verified owner)

    Now I have a 12ga AND a .357mag/.38 spl in one device! Happy, happy, happy!

    Perfect edition to my scavenger single shot set-up.

  187. John (verified owner)

    Great, worked just fine in 1910 era spanish shotgun, BUT I will use ONLY .38 SP and NON +P to avoid any overpressure. SHOT VERY accurate both wad cutter and copper coated ball …Great job… I really wanted the 18 inch version but you were out. However the 5 inch accuracy is quite good. Thanks again for fantastic service and delivery…. John

    I received my product on time in a perfect condition but I did not get a chance to go out there and use it and shoot some round with it to see how is it doing but I really appreciate it thank you so much
