Reptilia's BPS Stock Brings Short LOP, Adjustable Comb to Beretta Shotguns

November 10, 2026

Reptilia has built a purpose-made drop-in stock for the Beretta 1301 Tactical and A300 Ultima Patrol, called the BPS (Beretta Precision Stock), with a notably short starting length of pull and an adjustable comb for a better cheek weld with ghost-ring sights or a red dot.

Snapshot

The BPS is a replacement stock for the 1301 and A300 shotguns built from polymer, aluminum and steel. It starts at an 11.63-inch length of pull, shorter than most factory setups, with Beretta's own spacer included to extend it to 12.63 inches if needed. The adjustable comb height lets shooters set a consistent cheek weld regardless of what optic or sighting system sits on top.

Key points

  • Length of pull: 11.63 in (29.5 cm) bare, or 12.63 in (32.1 cm) with the included 1-inch Beretta spacer, aimed at easier mounting under armor or heavy clothing.
  • Adjustable comb: cheek height can be set for factory ghost-ring sights or a red dot, according to Reptilia.
  • Build: 14.5 oz, combining impact-modified glass-filled nylon polymer, 7075-T6 Type III hardcoat anodized aluminum, and nitrided alloy steel hardware.
  • Fitment: works on both the 1301 Tactical and A300 Ultima Patrol in 12 or 20 gauge, despite their different gas and bolt systems.
  • Price and colors: $124.95, offered in black or FDE, listed as coming soon by Reptilia.

Quick take

TheFirearmBlog's writer argues a shorter starting length of pull makes sense on a defensive shotgun, since it's easier to stay mounted and consistent while moving or wearing bulky gear. For 1301 and A300 owners who've been stuck adapting factory stocks, this gives a dedicated aftermarket option with real adjustability built in.
