Designed in conjunction with PWS & FM Products, the Brownells BRN-180S® Complete Upper Receiver is the newest iteration of the BRN-180® Upper Receiver, which was inspired by the Armalite® AR-180 of the 1960s. The BRN-180S® shares a large chunk of components with the BRN-180® but introduces key features to improve reliability and usability in a short configuration. The BRN-180S® is obviously shorter than the standard BRN-180®. The 223 Wylde version comes with a 10.5” barrel configuration. The free float M-LOK handguard mated to the assembly is also shorter, terminating just in front the gas block. This resulting shorter system also required a cutout in the handguard to access the two-position adjustment. The user can select between these two settings to find the most reliable configuration with their ammo and suppressor. The BRN-180® Gen2 Upper Receiver Group improves upon the original BRN-180® with two main upgrades. First, all BRN-180® Upper Receivers now ship with an Adjustable Gas System, previously only found on the BRN-180S®. The operating mechanism, the short stroke gas piston concept remains the same, but the user can select between two settings, depending on their conditions and ammunition, to ensure smooth and consistent function. No more spare gas piston cup to worry about. In addition to the new Adjustable Gas System, the Handguard is now retaining with a single locking screw. This large screw provides ample locking force and ensures a more consistent handguard lockup than the previous mechanism. During extended firing, and the barrel heating up, this new locking system ensures the handguard retains alignment and rigidity with the upper receiver. Also, with this new takedown mechanism, the handguard can be removed to access the gas system without removing the internal components. Like the original AR-180, the BRN-180® bolt carrier rides smoothly on a PAIR of guide rods. The carrier is buffered at the rear by a built-in polymer buffer with a molded-in steel plate that captures the guide rods. The Nitride bolt replicates the original AR-180 bolt design, right down to its use of a standard AR-15 extractor. The barrel is machined from extra-strong 4150 carbon steel, with a hard Nitride finish that really resists surface wear. The 223 Wylde BRN-180® chamber allows for extra flexibility in ammo choice - with 1-8" rifling, so it handles both .223 Remington and military-type 5.56mm NATO ammo with equal aplomb. Up front there's a replica of the AR-180's unusual three-prong flash hider: the hemispherical bottom prong helps prevent the muzzle blast from kicking up a dust signature when shooting prone. Standard ½-28 tpi on the 223 Wylde muzzle threads let you swap on a modern AR-15 muzzle device should you be bitten by the customizing bug.

Scopri il nuovo BRN-180S® GEN 2 Complete Upper Receiver Assembly
Progettato in collaborazione con PWS e FM Products, il Brownells BRN-180S® Complete Upper Receiver rappresenta l'ultima iterazione del BRN-180® Upper Receiver, ispirato all'Armalite® AR-180 degli anni '60. Il BRN-180S® condivide una grande parte dei componenti con il BRN-180®, ma introduce caratteristiche chiave per migliorare l'affidabilità e l'usabilità in una configurazione compatta.
Caratteristiche principali:
- Versione 223 Wylde con configurazione del canna da 10.5”.
- Handguard M-LOK free float più corto, terminante appena davanti al gas block.
- Possibilità di selezionare tra due impostazioni per una configurazione affidabile con munizioni e soppressori.
- Nuovo sistema di gas regolabile, ora incluso in tutti i BRN-180® Upper Receivers.
- Handguard fissato con una sola vite di bloccaggio, garantendo una maggiore stabilità.
- Meccanismo di smontaggio che consente l'accesso al sistema di gas senza rimuovere i componenti interni.
Come nell'originale AR-180, il carrier del BRN-180® scorre agevolmente su una coppia di guide. Il carrier è attutito posteriormente da un buffer in polimero integrato con una piastra in acciaio stampata che cattura le guide. Il bolt in Nitride replica il design originale del bolt AR-180, utilizzando un estrattore standard AR-15.
La canna è lavorata in acciaio al carbonio 4150 extra-resistente, con una finitura in Nitride dura che resiste all'usura superficiale. La camera 223 Wylde consente una maggiore flessibilità nella scelta delle munizioni, con rigatura 1-8", gestendo sia le munizioni .223 Remington sia quelle di tipo militare 5.56mm NATO con la stessa efficacia.
Specifiche tecniche:
- Sistema operativo a pistone ultra-affidabile AR-180.
- Compatibile con i lower AR-15 mil-spec attuali.
- Receiver e handguard in alluminio 7075 T6 - finitura anodizzata dura.
- Canna da 10.5" su 223 Wylde con finitura Nitride nera opaca.
- Camera .223 Wylde.
