(Because of the thin wall required for this insert Therefore I recommend using only standard Load ammo. In addition If reloads are used make sure the pressure stays at or below the standard PSI range)
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, and 22 Hornet. Please always be safe and aware.
Thank you for reading.
Please be aware that the 16″ 410 adapters may not work in all shotguns, depending on the bore diameter. Shotguns with tapered bores may not fit. Due to the already thin wall it is not possible to make these adapters any smaller.

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
