The Beretta A400 Xtrema Magazine Cap with Swivel Stud (brand part no. E8A157) is a Beretta forend magazine cap built for the A400 Xtrema, replacing the factory cap with one that adds a built-in sling swivel stud. It installs as a direct, factory-fit replacement, so there’s no custom fitting or gunsmithing involved. Whether you’re restoring a well-used pistol, shotgun, or carbine to factory spec or fine-tuning it for the range, this is the manufacturer’s own part, not a generic aftermarket copy.
