Browning BPS Micro Deer Satin 20 Gauge Shotgun for sale. Few firearms ever earn the level of respect the Browning BPS boasts. The BPS has a solid reputation for long-lasting durability and an uncanny ability to keep on working in spite of what Mother Nature does to stop it. This shouldn’t come as a surprise because the BPS has what most other pump shotguns don’t — features like rigid dual machined steel action bars, a forged and machined steel receiver, a convenient top-tang safety and bottom ejection for ambidextrous operation, and legendary Browning balance and handling. That’s why the BPS continues to be the pump shotgun serious shotgunners like you can always rely on.
