The Bond Arms Stinger (BAST) is a single-action .22 LR derringer with a 2.5-inch barrel and 2-round capacity. The frame is aluminum with an anodized silver/black finish, the grip is black nylon, and a crossbolt safety blocks accidental discharge. The combination of aluminum construction and the small profile keeps it extremely light.

Detailed Features 

The aluminum frame is the main reason this derringer carries so lightly. It's noticeably lighter than Bond Arms' steel-framed models. The crossbolt safety is easy to operate and gives you a physical block against discharge. Single-action operation means each shot requires cocking the hammer manually, which is expected for the platform. 
 
The 2.5-inch barrel is consistent with Bond Arms' standard derringer barrels. The gun accepts standard .22 LR ammunition without restriction. 
 

Usage 

The Stinger is a pocket/backup gun first. Two shots of .22 LR from a 2.5-inch barrel is a real limitation for serious defense work, and anyone relying on this as a primary defensive tool should account for the caliber's relatively limited energy at these barrel lengths. It works well as a last-resort backup, a trail gun where ultra-light weight matters more than round count, or a range novelty. The manual hammer cocking and two-round capacity require deliberate, careful use rather than the rapid-fire capability of a semi-auto.

The Stinger's main appeal is its light weight and tiny footprint, and buyers who want exactly that are generally satisfied. The aluminum construction keeps it lighter than most comparable derringers, and the anodized finish holds up well to pocket carry.

The caliber and capacity are the points that generate the most discussion. Two rounds of .22 LR is a real limitation, and most experienced shooters who own it are candid that it's a backup or last-resort tool rather than a primary defensive arm. The .22 LR round's energy from a short barrel is modest, and discussions about shot placement and reliability with different .22 LR ammunition brands come up regularly.

Build quality gets positive marks. Bond Arms has a solid reputation for derringer construction, and the Stinger is no exception. Fit and finish are clean for the price. The single-action trigger requires cocking before each shot, which slows you down but keeps the pull light and deliberate.

For plinking and range use, owners find it enjoyable. For daily carry, it mostly serves the specific niche of someone who needs something genuinely tiny and light over something more capable.
