Custom Benelli Buttstock Spacer – Polymer Length of Pull Extension for LH/RH Stocks

The ultimate solution for length-of-pull adjustments and enhanced shooting performance. Crafted with precision engineering and lightweight polymer materials, this spacer is designed specifically for Benelli shotguns, ensuring a seamless fit and unparalleled durability.

Installation: Between the original recoil pad and the stock. This is a long-term fit adjustment but can be removed easily once you no longer need it.

Color: Black

Weight (typical sizes - examples): 29 g (12 mm) · 35 g (18 mm) · 42 g (24 mm)

Easy to install: Insert the buttstock spacer between the recoil pad and the stock. Ensure it fits snugly. Shoulder the shotgun to confirm the spacer provides your desired length of pull.

Please note: This spacer is designed as a long-term, set-and-forget fit solution. Once installed, it stays in place — so it works best for shooters who have found their ideal length of pull and want to lock it in. If you frequently share your shotgun or swap setups between sessions, this may not be the right fit for you.

You may order any custom size up to 70 mm - choose your desired height from product variants.

Ambidextrous – suitable for both right- and left-handed shooters.
