The Browning BT99 is a single-shot break-open trap shotgun in 12 GA. The 34-inch back-bored vent rib barrel, 2.75-inch chamber, and 8.5-lb weight are well-matched to the demands of trap competition.

Detailed Features 

The back-bored 34-inch barrel tightens patterns and reduces felt recoil. The Invector Plus flush choke system lets you swap chokes for different trap distances without tools. Steel receiver and barrel construction means the gun is heavy by design -- that weight absorbs recoil during extended practice sessions. The black walnut stock has a satin oil finish and the gold-plated trigger offers a consistent pull. Ivory bead front and mid-bead rear sights give a clear sighting plane on crossing targets. 
 

Usage 

The BT99 is purpose-built for trap. The 34-inch barrel and single-shot format are both optimized for trap's single-target presentations. It can do skeet in a pinch but is most at home on a trap field.

The Browning BT99 Precision is considered a serious trap gun, and owners treat it that way. Build quality and craftsmanship come up in nearly every discussion -- the materials, fit, and finish are noticeably above average.

Accuracy and consistency are common praise points. Competitive trap shooters report tight, predictable patterns and appreciate the gun's balance at the line after a full round.

The stock design gets credit for ergonomics. Extended practice sessions are more comfortable than on most pump-action alternatives, and the adjustable features let shooters dial in fit.

Weight is the most common criticism. At 8.5 lbs the gun is not light for long days at the range, and some users switch to it only for competition while training with lighter guns. Beginners sometimes find the recoil at that weight to be less forgiving than expected, though trap loads are generally mild.
