Mossberg 505 Youth All-Purpose Field 20 Gauge Shotgun

A: I'm pretty sure it will fit John

A: Maverick 88 pump-action models are fully-interchangeable with Mossberg 500 barrels (within gauge and capacity). The diverse selection of available accessory barrels allow shooters to adapt their Maverick 88 for multiple hunting or security purposes.

A: No, the 505 youth barrel does not fit standard 500 or Maverick 88 shotguns or vice versa John. Only exception is the Maverick 88 and 500 series interchange.

A: Read below the pictures of the barrels They'll fit http://www.mossberg.com/category/series/maverick-88/

A: The 505 will not fit on the 500 The 505 has a shortened magazine tube which means that the barrel lug (where attaches to magazine tube) is shorter (From rear of barrel) on the 505

A: You can David with no problem. Personally I would buy the configuration I wanted up front to reduce expenditure and use that money for additional ammo and accessories.

A: yes you can and they do make 20 ga slugs and the will work just fine in this gun here is a 20 ga pistol grip https://www.budsgunshop.com/catalog/product_info.php/cPath/26_631/products_id/58514/Mossberg+Pistol+Grip+For+20+Ga+Model+500%2F505+w%2F+Quick+Detach and 20 ga slugs https://www.budsgunshop.com/catalog/ammo_search.php/caliber/10000861/v/1/sort/1a/20+Gauge?filter_id=&casing_id=&bullet_type_id=10001562
