Check the barrel and receiver.
nah it doesnt have to be a deerslayer at all. the featherlight is completley compatible with a slug barrel in a 20 guage magnitude. :D
The barrel and receiver should have the same serial number.
Look on bottom of receiver and barrel
1952
Check the receiver and barrel.
The barrel will have 'Made in Belgium' on it. The receiver can be dated by serial number.
You can always use a shorter shell in a 3" chamber. 23/4" should be fine.

The barrel of this shotgun simply cannot be removed. It is screwed in and requires a barrel vice and the appropriate wrench. The trigger group can be removed by means of the pin at the back of the receiver, which would allow for easier access to the barrel, but this is a complicated process and is not recommended. Nothing can be removed from the J.C. Higgins Model 20 to help clean it, unfortunately.
On top of the receiver, just behind the barrel, there's the release button. Slide it forward and the barrel should open up from the receiver, hinging near the bottom rear of the forearm. This is a single shot shotgun, so you can only put in 1 round at a time.
No, the 336A had a 24" barrel from the factory. The 336C or RC used a 20" barrel.
