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 Shotgun Adapters., 357 Mag, 327 Shotgun Adapters , 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.

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.

    Excellent workmanship and fit. Shoots well also. It took almost 3 weeks longer than expected to get the adapter but this wasn’t Chaszel’s fault but the fault of the postal service. The good thing is that it was worth the wait. I’ve got more on order.

    Outstanding, worked perfectly in converting a 12ga Crescent SXS into a Modern Coach combo rifle/shotgun. Just like all other adapters I have(20ga to9mm/12ga to9mm/20ga to357mag 11″/12ga to .45-70 18″) they are excellent quality and accuracy is as expected .In many respects more practical and much less expensive than other options for sure.

      Good Afternoon, I’m sorry you have not received your adapter. It was shipped on the 15th, after that it is out of my hands as far as how fast it gets there. All of the longer adapters are shipped Priority MaiL. The tracking was updated yesterday so the delay is most likely due to Covid19. I am again sorry for your inconvenience.

    Great buyer service,shipment extremely fast, I bought a 24” 45/70 adapter and a 18” .44 mag adapter. Both very very well made and tight fit. I haven’t had a chance to test fire them, but I have no doubts about accuracy being great. Do not hesitate to buy or order, as you can’t go wrong! Thanks Chad great experience all around.

    Great Insert, excellent workmanship. USPS shipping was a little slow, took 13 days to go from Georgia to Colorado, Probably due to COVID-19 though. Looking forward to my next purchase! Thank you.
