Description

327 Mag Shotgun Adapters for 12 Gauge Shotguns

327 Mag Shotgun Adapters Allow a 12 Gauge Shotgun to use

5 Types of  Ammo.

327 Federal Magnum, 32 Long, 32 Short, 32 H&R Mag in addition to 32 ACP.

For 3″ as well as 2 3/4″ Chambers

Compatible with Break Action single as well as double barrel shotgun.

Rifled with a 1:12 twist rate.

Rifled Dimensions:  4 Grooves x .176 Wide.   Bore .303  / Groove .312

Black Oxide coating as a result provides notably better corrosion protection (for maximum corrosion protection keep a thin coat of oil on the insert)

327 Mag Shotgun Adapters Comes with multiple O-ring configurations.  As a result,  easily achieving a good fit for 20 gauge shotguns.

Please Note:  Not all shotguns are the same!  While the majority of them are capable of handling high pressure rounds, some are NOT.  Only use these rounds in shotguns that are compatible.  I recommend on any shotgun to test the first shot in a vice while out of harms way and to always wear eye and ear protection.  If after testing you see the primer punctured in the round discontinue using this round and use a less powerful round. These high pressure rounds include: 45-70 gov., 357 Mag Shotgun Adapters, 327 Federal, 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.

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-Pressure round alternative.

327 Mag 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 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.

The video below gives a brief demonstration of how they work.

    Good folk to do business with. Have made multiple purchases.

  10. Allen (verified owner) –

    These adapters are well made. It’s not the same as having a rifle in the specified caliber, but I am confident enough that if I could only have one long gun I would take my break open 12 gauge and my adapters.

    This shotgun adapter is of excellent quality, the workmanship is exceptional straight bore, strong rifling, easy extraction, and beautiful finish. This is my 3rd 12 gauge adapter from chaszel and i also have a 410 to 32 and a 410 to 38 from them and all of them are of excellent quality. I’m very satisfied with all my chaszel products they are a good company and i wasn’t paid or asked to do this review.
