Barrel with unmarked Choke Designation

[CartridgeCalls]

I just bought a Huglu home defense shotgun and there are no markings on the barrel for the choke. I read the owners manual and it does not specify wht ammo to use.

If it safe to say I can shoot all ammo through it including slugs?

The barrel does have a front wing sight with fiber optic sight but no rifling in the barrel.

The Shotgun in question is a Huglu/Best Arms BA312-PG with pistol grip.

Is it this shotgun with changeable chokes or is it a fixed choke?

It is a fixed choke. There are no threads in the barrel for chokes.

Since it's a "self defense" shotgun that should be used for short range situations, I would bet that it's either cylinder bore or Improved cylinder.

You could use an inside micrometer and measure the smallest diameter in the bore.

I contacted ADCO which is in the owner's manual and all I got was an " I don't know".

If there are no choke markings it's usually cylinder bore, which would make sense for a defense shotgun.

[G-forceJunkie]

I would guess Cylinder Bore. Slugs should be no problem, if it was it would say in the manual.

Never known a barrel to be unmarked. Some use codes ,**-, OOO, 1/2......... for choke

[BajaJames83]

you could measure the opening that will help you a little.

Measure it with calipers. But, it's likely cylinder or improved cylinder.

Thanks for all the help everyone. Measured it this morning. It's IC.

Way back when (I’m 81) we used to take a dime and if it wouldn’t slide inside the barrel (12ga) we figured full choke if it went all the way in IC or cylinder, just a SWAG though.

If you can get ahold of some calipers you can just measure it. You shouldn't shoot slugs through a really tight choke.

The web page for Cheaperthandirt indicate this shotgun takes Mobil choke??

Is this a gas gun or inertia gun?

[CartridgeCalls]

It's a gas gun. It is not threaded for chokes.
