Description

380 Shotgun Adapters for 410 Shotguns

380 410 Shotgun Adapters Allow a 410 Break Action Shotgun with a 3″ Chamber to use 380 Auto likewise (ACP) Ammo.

Compatible with Single as well as Double Barrel Shotguns.

Rifle dimensions are .355″/.349″ with 6 lands and .125″ wide with a 1:12 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)

Please be aware that the 18″ 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 is a tapered bore?
A tapered bore is exactly what the title implies. The diameter of the bore gradually tapers down from breech to muzzle. The amount of the taper is slight — perhaps one-thousandth to as much as two-thousandths of an inch; but at the time this service was performed, the measuring tools needed to accurately measure it weren’t commonly available. So, most of the makers didn’t actually know how much they were tapering their bores — just the fact that they were.

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.

    My name is Jeff. But, my wife Terry’s name got auto filled on this purchase. Everything we have bought from Chaszel has suited our wants and needs for making our guns versatile in a way they can accommodate other ammunition than what they came factory equipped to use. Take for instance when we combine the 18 inch long 45LC-410 combo, 44, 9mm, 38special and 380 adapters with our 12 gauge shotgun we have 5 different bullet calibers plus 410 and 12 gauge shot or slugs we can shoot with it. Throw in the shorter 20 and 28 gauge adapters and you got even more you can shoot. I’ve bought quite a few and plan to get more.
