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.
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

Used it (18” x 9mm) yesterday at 25 & 50 yards. Gave me 2” at 25 and 4” at 50. ‘Iron’ sights on an H&R 20ga. Very well made and finished. Easy to use. Very pleased. Wish I’d known of these long ago. TY!

Initial test on the range was very promising. Looks to be an excellent addition as part of a “9mm” carbine project on a slug gun.

Adapter fit nice and snug, I haven’t shot it yet but when I do, I’ll give a review on that. That being said, I will be looking forward to buying one for my 16 ga.

Quality workmanship. Great fit. Good accuracy. For a small investment, I transformed my shotgun into a 9mm rifle, yet it retained the characteristics of my original scattergun.
Anthony P. (verified owner) –
I am very pleased with the accuracy of my Chaszel shotgun adapter. The extra cost for this 18-inch adapter is well worth it. It stirred much interest at my local gun range.

I ordered the 11 inch 9mm insert for use in my 22 year old NEF 20 gauge shotgun. Order fulfillment and shipping were fast. I tried the insert out at 25 yards using 115 grain 9mm ammo. All shots were within 4 inches and were to point of aim. I have a fiber optic front sight on my shotgun which improves aiming but also reduces accuracy a bit. I am quite sure I would have better accuracy with a better sight on my shotgun.

Another great piece. It is far superior to other similar products I have seen.
