B&T GHM9 SD 9mm Integrally Suppressed SBR, 4.33 in Ported Barrel, Telescopic Stock, Matte Black - Excellent
This Swiss-made B&T GHM9 SD is an integrally suppressed, recent-release short-barreled rifle built around a factory-ported 4.33 in cold-hammer-forged barrel and the dedicated GHM9-SD suppressor that mounts at the receiver. The SD system uses small ports near the chamber so standard bulk 9mm loads are slowed for maximum suppression without relying on specialized 147- or 158-grain subsonic ammo. A closed-bolt straight blowback action with a hydraulic buffer keeps the gun smooth and flat during strings of fire. It comes in excellent condition with its original case, sling, manual, and a translucent 30-round magazine. Note: This example features a GHM9 SD upper/handguard and suppressor assembly installed on an APC-marked polymer lower (roll-marked “APC SWISS MADE”); the serialized upper is GHM9 SD.

The SD configuration is the standout feature: the barrel is ported with small holes right next to the chamber, and the dedicated GHM9-SD suppressor interfaces at the receiver rather than on muzzle threads. This setup reduces standard bulk 9mm to subsonic velocities for strong sound suppression without sourcing costly, heavy subsonic loads.
The operating system is closed-bolt straight blowback paired with a hydraulic buffer. This combination is designed to moderate reciprocating mass and felt recoil, contributing to a notably smooth and flat shooting experience.
The chassis blends a matte black anodized aluminum receiver with a durable polymer frame. An SD handguard in aluminum provides M-LOK slots on the sides and an accessory rail at 6 o’clock, while a full-length top Picatinny rail offers ample space for mounting accessories. No iron sights are installed from the factory. Controls include bilateral bolt-catch paddles and a manual selector safety.
A two-rod telescopic, non-folding stock keeps the package compact while maintaining a solid cheek line. The 4.33 in cold-hammer-forged barrel and integrally suppressed layout keep overall length efficient.
Markings include B&T Thun, Switzerland; B&T USA, Tampa, FL; and SWISS MADE. The polymer lower/magwell is roll-marked “APC SWISS MADE.” The magwell also bears additional engraving: "MICHAEL RUSSELL SAN ANTONIO, TX." Capacity is listed at 31+1, and this rifle ships with one translucent 30-round magazine along with the original accessories noted above.
