The Beretta Scope Mount Base (E5D864) gives the 1301 Competition, TX4, and A400 Xtreme Plus a dedicated platform for mounting red dots, micro reflex sights, or low-power optics. This is a factory Beretta part machined to fit the receiver geometry of those specific shotguns, so the rail sits where it should without shimming or improvised hardware. Competition 3-gun shooters and anyone running an optic on a semi-auto Beretta will get the most out of it. If you want a clean, repeatable optic install on an A400 Xtreme Plus, this is the mount Beretta designed for the job.
Beretta builds this base from aluminum, which keeps weight down on the receiver while holding zero under the recoil impulse of 12-gauge loads. The top surface is cut as a combined Picatinny/Weaver rail, so it accepts standard cross-slot rings and the wide range of red dot mounts and adapters built to that spec. Fitment is confirmed across three platforms: the 1301 Competition, the TX4, and the A400 Xtreme Plus, per Beretta specifications. Because it bolts to the receiver rather than clamping a vent rib, the mounting interface is rigid and the point of impact stays consistent shot to shot. The finish is black to match factory furniture. Buyers who prefer cross-slot rings can pair it with any standard scope mount or ring set in our catalog.
Most owners run this base with a micro red dot for fast target acquisition on a competition or defensive shotgun, though it works equally well with a low-magnification optic for slug work. Once the rail is torqued to the receiver, swapping or re-zeroing an optic is straightforward and returns to zero reliably. If you're building out a 1301 or A400 for 3-gun, this is the foundation the rest of the optic stack sits on. Pair it with the rings or red dot adapter that matches your sight, and browse our other shotgun-specific saddle and base mounts if you run more than one platform.
This base is cut to fit the Beretta 1301 Competition, the TX4, and the A400 Xtreme Plus, per Beretta specifications. It is not a universal mount, so confirm your shotgun is one of those three models before ordering.
The top surface is machined as a combined Picatinny/Weaver rail. It accepts standard cross-slot rings and the wide range of red dot mounts and adapters built to that spec, giving you flexibility in how you mount your optic.
Beretta builds this base from aluminum. That keeps weight low on the receiver while staying rigid enough to hold zero under 12-gauge recoil. The finish is black to match factory furniture.
Yes. The Picatinny/Weaver surface accepts most micro red dot mounts and adapters. Many owners run a micro reflex sight for fast target acquisition on competition or defensive setups, while others fit a low-power optic for slug work.
It bolts to the shotgun receiver rather than clamping the vent rib. That makes the mounting interface more rigid and keeps your point of impact consistent shot to shot, which matters when you re-zero or swap optics.
