Description

44 Caliber Shotgun Adapters

44 Caliber Shotgun Adapters Allow a 12 gauge Break Action Shotgun to use 44 Magnum* as well as 44 Special Ammo.

Compatible with 12 gauge Break Action single and also double barrel shotgun.

Comes with multiple O-ring configurations.  As a result,  easily achieving a good fit for 20 gauge shotguns.
Rifle dimensions are .431″/.421″ with 6 lands and .107″ wide with a 1:20 twist rate.
Black Oxide coating as a result provides notably better corrosion protection (for maximum corrosion protection keep a thin coat of oil on the insert)
I recommend to keep a coat of oil on the insert for more corrosion protection

*44 Magnum rounds should only be used in capable shotguns with SB1 or SB2 or equivalent receivers.

Please Note:  Not all shotguns are the same!  While most shotgun are capable of handling high pressure rounds. However, 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 Shotgun Adapters, 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.

Warning!

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.

 

44 Caliber 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. 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.

    I couldn’t believe my eyes when I pulled this 12 ga./.44 Mag Adapter from the packing, which by the way was Excellent! This Adapter is a work of Art, truly a Beautiful Piece. And the rifled barrel is glass smooth. American Workmanship is Definitely Alive and Well at Chaszel. I simply can’t say enough about the Quality in This Piece. Unfortunately as of now I can’t comment on the Accuracy or Consistency of this Product (So Sorry) due to Health Issues and Lack of Ammo due to the same reasons. I’m to tight to buy Factory Loads…lol! Besides I haven’t bought Factory Loaded .44 Mag ammo since the mid 70s. THANK YOU Chaszel!!! For a Fantastic Product. Ya’ll have Restored My Faith in American Workmanship.

  2. Walter Flagg (verified owner) –

    I was very pleased and surprised that my 44 mag adaptor was very accurate the first time I shot it. I am very happy with my purchase.

    I ordered this adapter quite some time ago and thought that maybe it was forgotten, but out of the blue I was informed that it was available if I wanted it. I have not shot it yet, but the quality of the product is very good. This spring I will give it a try and hope it shoots as good as it looks.

    Adds versatility to my old HR single 12 of Great Granddads. Fired 11 shots with it at 30+ yards yesterday and was cutting ragged holes if I did my part aiming. Am looking forward to getting a pair of 18″ adapters in .357 for Great Granddads old 12 gauge double with the “New Twist” barrel from the 1890’s

    Awesome product. Accurate especially in the longer 18” . Great service and quality.

  31. Chris Kelly (verified owner) –

    Great accessory… I put this insert in the bottom barrel of a Czech combination gun (5.6x52r/12 ga). It shoots within 2” of my sights at 45 yards and will keep a 2 1/2-3” group at that range… should be very useful. Great product

  32. James (verified owner) –

    I haven’t had a chance to use it yet but the craftsmanship and detail is fantastic.

  40. Carl Gonzales (verified owner) –

    After a friend ordered one of your 18″ .357 inserts and getting to see how it preformed I got in touch with you and the highest leval of customer care sealing my fate I ordered a 44mag 18″ insert. Shipping was fast. 2 and a half days and it was in my hand. Shooting my handload a 200gr FMJ semi-wadcutter 44special at 30yards it put 3 bullets in one ragged hole. This is big medicine and you should get you some.

  41. james kelley (verified owner) –

    Very fast delivery. Product is as advertised. Thanks.

  42. Bruce (verified owner) –

    This insert is exactly what I was looking for, its very accurate, its quality made, and makes my cut down H&R 12 ga a very good truck rifle/shotgun. I am waiting for Chaszel to catch up on their backorders so I can finish my 20 ga, and 410.

  43. Charles R. (verified owner) –

    Great workmanship can’t wait to see how it performs in my h&r

  44. Norman C Utter (verified owner) –

    Great product. Now I need two(2) 11 in. 12 gauge to .44 magnum. Keep up the production. Thanks.

  45. Mark Risley (verified owner) –

    My third insert from Chaszel so far. Really makes owning a 12 gauge single shot more interesting to have that versatility! Going to try some reloaded ammo and see what it ” likes best” for accuracy. Looking forward to the 30/30 insert coming in stock!

    To update my recent product review of the Chaszel 12ga to 44mag barrel insert-my order arrived quickly and well protected in a thick hard cardboard mailing container.The adapter-its self-also wrapped in a thick & secure layer of bubble wrap to protect its beautiful black oxcide finish-a quality product from start to finish-installed the barrel insert today to test fire the adapter & was very pleased with its accuracy and ease of use-plan on enjoying my recent purchase for years to come-Many thanks to Chad & crew at chaszels for the well made adapter & their prompt deliverly & great customer service. I plan to purchase more of their quality made products.

  50. Mark Risley (verified owner) –

    Nice addition to my single shot 12 gauge. Seems pretty accurate with factory ammo, I’m interested to see how it does with reloads. It fits the barrel very nice even though the shotgun has a rifled barrel. Nice craftsmanship!

  51. Ralph E Smalley (verified owner) –

  52. Keith Bayless (verified owner) –

    I appreciate the fact that this as well as other adapters makes my shotgun very versatile!

  57. Kevin S. (verified owner) –

    I found this insert, the 12 gauge to .44 Magnum, to be typical of the very high quality of Chaszel products. It shoots very well with both jacketed and cast bullet loads. Hitting a 6 inch diameter gong at 100 yads was easy, even with the shotgun’s bead sight. I call this a highly worthy investment, and worthy of a 5-star rating.

  58. Curtis (verified owner) –

    I love shooting the 44mag adapter.Can’t wait to get more when they become available.Thank You

  59. Joseph Hebert (verified owner) –

    Thank you,,very fast delivery ,,great barrel,,now on the waiting list for a .22 magnum insert 18” so I can go rabbit hunting this fall,,,thank you for doing a great job,,

  60. Greg S. (verified owner) –

  61. Peter Haarmann (verified owner) –

    The unit is well made. It fit well into the gun barrel. I like the idea of all the o rings. This mill allow for expansion of the adaptor.44 mag is a heavy load. I chose the 18” adaptor because I had an eight inch adaptor of the same caliper and I felt this couldn’t put an enough spin on the bullet. I wanted better accuracy. The 8” adaptor was made by a competitor.
    Yes the 8” adaptor was cheaper then the 18” adaptor. But I feel you get what you pay for. So I went for the 18” adaptor.

    What I want to do but haven’t tried; is place each adaptor in a side by side double barrel shotgun and compare accuracy.

  62. Larry Long (verified owner) –

    Due to the press of Family ,I have yet to fire any of the three . The .44 is the second one . They appear to be perfect ! I have the .357 , .44 & .45 ACP . I patiently (ha ha ) await the .45/70 & .22 WMR ! (patiently of course ! THANK YOU ALL FOR YOUR EFFORTS ! Some of us have some idea just how hard you all are working for us ! Everyone in the Firearms Industry deserve a GREAT BIG HAND OUT THERE ! P.S. did i mention the patiently waiting part ?

  63. David B. (verified owner) –

    Amazing service!

  64. walter d hazelip (verified owner) –

    great shotgun adapters want more

  65. John H. (verified owner) –

    First off, service was great. Chaszel notified me when the insert became available and shipped it out right away.
    The insert works much better than I expected it to. Very consistent even with the cheapy dot sight I mounted on the shotgun barrel. I shot consistent groups every time. I will be ordering more calibers. Swapping out the insert is easy. I took a $75 beater shotgun and turned it into something much more versatile. Great product.

  66. Wes (verified owner) –

    It’s exactly what I was looking for!!!

  67. Anonymous (verified owner) –

    Excellent quality shotgun inserts. I have not yet been to the range, but expect this insert to perform as well as the 357 Mag. insert. Running short on this ammo; so, looking to use some 44 mag. ammo that have for my Ruger Redhawk. These are quality additions to the “Shotgunner” and add so much to the usefulness to single and double barrel shotguns.

  68. Jeff Green (verified owner) –

    I have not used it yet but the quality looks very good.

  69. Joel Henderson (verified owner) –

    Great product. Just love the fact that these guys can do what they do

  70. Monroe (verified owner) –

    Purchased .44 mag inserts for my 12 ga. side by side. Nice grouping at 25 yards. Have not tried out further. Well worth the wait. Nicely made and great fit. Great communication and customer service. Awaiting .38 special inserts for my side by side .410

  71. Jerry Hayden (verified owner) –

    I honestly have only inspected the two 44 caliber and the 9 mm tubes I’ve purchased and found them to be what true old time days gone by, “unfortunately”, real American Craftsmanship used to be. I bought these from watching review video’s other’s have made and I’m telling ya these inserts are the real McCoy. I’ve worked in machine shops in my early year’s and I promise you won’t find better machine work. Even though I haven’t used them yet I’m confident in the quality and will be purchasing another insert or two. Also the packaging is super secure and done like this used to be. American made. American quality. Thanks Chaszel!

  73. Jeffery F. (verified owner) –

    Purchased for my Hatfield survival gun. This 11″ sits inside the barrel at most times. Secondary use is as a baton. Really great quality all around.

  74. Rick H. (verified owner) –

    Great product! Lightning fast shipping!

  75. Mark (verified owner) –

    This adapter is extremely well made. It was shipped with extra O rings, instructions and coupon. It fit perfectly into my shotgun. My best friend has the same exact adapter for his shotgun and he already fired his. It is very accurate! I love the customer service too!

  76. kenny –

    I only gave it a 4 because I have yet to use it. Out of the box it has the same quality as the other Chaszel adapter I own (a 12 gauge to 9mm) which has performed flawlessly.
