Storage Plug for SB Tactical SBA3 Pistol Brace

This plug is specifically designed for genuine SB Tactical SBA3 braces and may not fit properly in clone or reproduction braces. The dimensions are precisely engineered to match SB Tactical's exact specifications. If you have a knockoff or third-party SBA3-style brace, the fit may be loose or too tight. We recommend verifying your brace is an authentic SB Tactical SBA3 before ordering. The genuine SBA3 has "SB TACTICAL" molded into the rubber and specific internal dimensions that this plug matches perfectly.

The storage cavity can accommodate small items like 2-3 CR123 batteries, a pair of foam earplugs, or a backup firing pin with small parts. The internal space measures approximately 0.75 in. x 1.2 in. x 2 in. (19 x 30 x 51 mm), which is ideal for emergency items you want to keep with your firearm but don't need frequent access to. Keep in mind that overpacking the storage area can make the plug difficult to remove, so we recommend leaving some room for easy extraction.

Yes, the plug is designed for easy removal when you need access to your stored items. Simply grip the exposed end and pull it straight out - no tools required. The fit is snug enough to stay secure during normal use and transport, but not so tight that removal becomes difficult. For faster access during training or competition, you can slightly loosen the brace strap to make plug removal even easier, though this isn't necessary for normal operation.

No, the storage plug is designed to work seamlessly with the SBA3's normal operation. The notched design ensures the internal straps can move freely without binding or bunching up. You can still adjust the brace strap tension and length as needed. The plug doesn't affect the brace's ability to fold or extend, and it won't interfere with shouldering the brace during legal use. The lightweight design adds only 0.28 oz (8 g), which is negligible in practical terms.

This is purely an accessory for your SBA3 brace and doesn't modify the firearm itself or change its classification. However, you should always ensure your pistol setup complies with federal, state, and local laws. The plug doesn't alter the brace's function or design intent as stabilizing device. As with any firearm accessory, we recommend consulting with local law enforcement or a firearms attorney if you have specific questions about compliance in your jurisdiction. The plug is designed to enhance storage without affecting the firearm's legal status.
