What’s Included
- Harrington & Richardson Topper Model 158 .410 Bore single-shot shotgun
The 28-inch steel barrel is fitted with a brass bead front sight and a factory-cut Full choke, giving tight, consistent patterns downrange. Its 3-inch chamber lets you use a wide range of .410 shotshell loads for hunting or informal clay work.
A color-case-hardened steel receiver—with the distinctive H&R side-lever barrel release—adds both visual appeal and rugged durability. The exposed hammer offers clear status indication, and the half-cock notch serves as a simple safety feature.
Hardwood furniture features a straight grip stock and beavertail fore-end, complemented by a ventilated recoil pad. The 13.75-inch length of pull suits most adult shooters and maintains the gun’s balanced feel.
Weighing approximately 5.5 lb, this Topper is easy to carry all day. The “AL” serial prefix dates production to 1973—the final year the Model 158 appeared in H&R catalogs—adding a notable detail for collectors of classic American single shots.
