Black Rain Ordnance Spec15 300 Blackout 10.5" Barrel 12" Hybrid Handguard OCL Polonium 30 Supressor Complete Upper

The Black Rain Ordnance Spec15 .300 Blackout Upper and Polonium-30 Suppressor bundle brings together two hard-running, no-nonsense components built for shooters who expect rugged reliability and adaptable performance. Whether you’re assembling a compact .300 BLK setup for range work, field use, or suppressed shooting, this pairing delivers the durability and flexibility demanded by today’s practical rifle owners.

The Black Rain Spec15 upper gives you a proven 10.5" .300 Blackout barrel and a 12" hybrid handguard, ideal for maneuverability and optimized performance with both supersonic and subsonic loads. Its complete NB bolt carrier group ensures dependable cycling, while the free-floating handguard provides ample room for accessories without adding unnecessary bulk. Built with Black Rain’s commitment to quality machining, this upper is a ready-to-run upgrade for shooters building a reliable blackout platform.

Matched with the Polonium-30 suppressor, you get a workhorse can designed for the shooter who wants one suppressor to run across multiple rifles. While not purpose-built to squeeze every ounce of performance from 5.56, it’s engineered to offer solid, respectable suppression across a wide range of calibers—.300 BLK, .308, magnum .30s, short-barreled 5.56, and more. External weight-reduction cuts keep the can light while increasing surface area for faster cooling, and the built-in internal and external flash hider helps reduce signature, especially when running night vision. With universal 1.375×24 rear threads, the Polonium-30 is compatible with a wide range of mounts, letting you tailor your setup to your rifle lineup.

Together, this bundle forms a compact, suppressor-ready .300 Blackout platform built for shooters who value durability, straightforward performance, and cross-rifle versatility.
