These Ed Brown low profile base pads were engineered to work perfectly with the Ed Brown Magwell for the S&W M&P, but will also work alone. Designed for positive lock with a rigid locking system, the base pads add a level of protection to your magazine, while giving you a better gripping surface for easier manipulations under the stress of competition or self-defense. The profile is just aggressive enough to ease handling, without making it uncomfortable to control. Fully machined from aluminum and anodized for a lifetime of service. Marked with EB logo.
