Features & Specs

The Springfield Saint 5.56mm AR-15 Pistol with B5 Grip and Trinity Force Breach Blade Brace is built on a forged 7075 T6 aluminum lower and a lightweight free-float handguard. Chambered in 5.56 NATO, it cycles both 5.56 and .223 Remington reliably. The 7.5-inch barrel features a 1:7 twist rate and is topped with an A2-style flash hider. The B5 grip reduces hand fatigue during extended sessions, and the Trinity Force Breach Blade brace adjusts to fit your forearm length for consistent cheek weld. The pistol also includes a nickel boron-coated BCG for smooth cycling and easy cleaning.

• Caliber: 5.56 NATO / .223 Remington; 7.5-inch barrel with 1:7 twist and A2 flash hider
• Furniture: B5 grip and Trinity Force Breach Blade brace for improved control and stability
• Action: Semi-automatic, direct impingement with nickel boron bolt carrier group

Other notable details include a flat-face trigger for a crisp break, an ambidextrous safety selector, and a flared magazine well for faster reloads. The handguard offers M-Lok attachment points at 3, 6, and 9 o’clock positions, letting you mount lights, lasers, or grips without extra hardware. Overall length measures 24 inches with the brace collapsed, making it easy to stow in a backpack or vehicle compartment.

Who It’s For

This Springfield Saint 5.56mm AR-15 Pistol with B5 Grip and Trinity Force Breach Blade Brace is ideal for shooters who want a compact platform that still packs a rifle round. It’s a strong candidate for home defense where maneuverability matters in tight hallways, or for shooters who spend time on public land and want a packable option for predator control or plinking. If you’re new to AR pistols, the included brace lets you shoot one-handed or braced against your shoulder without running afoul of NFA regulations. Experienced shooters will appreciate the upgraded grip and brace combo, which eliminates the need to swap out basic OEM parts. This is also a solid choice for anyone who wants a dedicated suppressor host, thanks to the short barrel and direct-thread compatibility.
