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. 12 and 20 gauge BPS shotguns include the interchangeable Invector-Plus choke tube system. 28 gauge and .410 bore BPS shotguns include the Standard Invector system.
