Can a rifle barrel be fitted to a NEF Handigun marked SB2??

[coaldust]

Tried to call H&R to ask this question but got tired after being on hold for 15 minutes.
I have a New England Firearms Handigun in 20ga (serial prefix NF) and wondered if a rifle barrle can be installed on it.
Any help would be appreciated.

Maybe 357 or 44 mag but you need to ask them, in the past they've fitted those barrels to SB1 and all SB2 frames made since 1987. SB2 on a barrel means nothing as to what frame it's on, very confusing, but they've been marking them that way for years, the frame could be either, they'll know by the complete serial number what barrels can be fitted.

Important Information Please Review before continuing

Additional barrels may be added to firearms of our manufacture since 1987 only, with a serial number that begins with N, H or CB. We do not install additional barrels on any other manufacturer’s firearms.
Additional barrels will be fitted to the proper frame if the frame passes a detailed inspection. This inspection is performed by the repairman at the time the frame is received.

Rifle barrels may be added to firearms manufactured since 1999 and only to frames (SB-2) that originated as a rifle, if frame passes inspection.

Rifle frames (SB-2) newer than 1999 may be fitted with additional rifle, shotgun, and muzzleloader barrels, if frame passes inspection.
 
 All shotgun frames (SB-1) and rifle frames (SB-2) produced between 1987 and 1999 may be fitted with additional shotgun and muzzleloader barrels only, if frame passes inspection.

Muzzleloader frames can only be re-fitted with muzzleloader barrels only.
Rimfire frames (SS-1) can only be fitted with rimfire calibers.
10 gauge shotguns and the 12 gauge Ultra Slug Hunter with the heavy rifled barrel can only be fitted with other 10 gauge or 12 gauge Ultra Slug Hunter barrels only.
We do not sell additional barrels outright. All barrels must be factory fitted.
We do not sell barrel blanks or do custom calibers/barrel lengths/finishes/sights.
Additional barrels are available as additional barrels only. We will not exchange barrels for existing barrels on shotguns and rifles, as it will change the model.
In order to obtain an additional barrel(s), the stock, forend and frame (receiver) must be sent to us so that they may be properly hand-fitted to the barrel, to be sure they are correctly head-spaced and proof-tested.
