The Beretta B-Fast Stock Weights set, MPN C62477, is a five-piece counterweight kit made for shooters who want to dial in the balance of a Beretta stock without permanent modification. These weights drop into the dedicated cavity inside compatible B-Fast adjustable buttstocks, shifting the balance point rearward and adding mass where it dampens muzzle rise. Competitive shotgun and tactical shooters use the B-Fast system to tune swing dynamics and felt recoil shot to shot. If you run a Beretta platform built around the B-Fast adjustment system, this set gives you a repeatable way to fine-tune feel.
Each set ships with five individual weights, so you can stack them in combination to reach the balance you want rather than committing to a single fixed mass. Added weight in the buttstock counters a front-heavy barrel and ported choke setup, settling the gun between shots and smoothing follow-through on fast doubles. Because the weights seat inside the stock's internal channel, nothing changes the external profile, length of pull, or comb height of the firearm. Installation is tool-light and reversible, which means you can experiment at the range and pull weights back out if the gun starts feeling sluggish. The set is a direct Beretta factory accessory carried among our Beretta replacement parts and gunsmithing components.
Reach for this set when a Beretta shotgun or carbine feels nose-heavy, recoils harder than you like, or pulls ahead on a swinging target. Sporting clays and trap shooters add rearward weight to slow the swing and steady the bead; tactical users add mass to tame muzzle climb during rapid strings. Start with one or two weights, shoot a round, and add more until the balance point sits where you want it.

B-Fast is Beretta's stock adjustment system that lets a shooter tune the fit and balance of the firearm. This weight set works within that system by adding internal mass to the buttstock, allowing you to shift the balance point rearward and adjust felt recoil and swing without altering the gun's external dimensions.
The set includes five individual weights, MPN C62477. You can install them one at a time or in combination, which lets you fine-tune the buttstock mass in increments rather than relying on a single fixed weight.
No. The weights seat inside the stock's internal cavity, so they do not affect length of pull, comb height, or the external profile of the firearm. They only change the gun's balance and felt mass.
No. The weights install into the dedicated channel in a compatible B-Fast stock and can be added or removed as you like. That makes it easy to test different combinations at the range and adjust the balance to your preference.
