Transform your pistol caliber build into a hard-hitting, compact AR-45 personal defense weapon (PDW). The PRO2A 7.5" 45 ACP Pistol Caliber Non-Reciprocating (NR) Side Charging Upper Kit completely modernizes traditional manual controls by replacing the standard rear dual-latch pull tab with a left-side charging lever. The handle stays fully stationary while firing, providing a seamless operating zone free from moving external components near your optic workspace or support grip. Engineered around an ultra-compact 7.5-inch barrel and optimized for a gas-block-free direct blowback operating system, this comprehensive upper kit comes equipped with Pro2A Tactical's optimized heavy 45 ACP bolt carrier group out of the box. Drops natively onto any dedicated AR-45 lower receiver build or standard lower using 45 ACP magazine adapter block conversions. Proudly 100% designed, machined, and precision-assembled in the USA.

Operators looking to build an agile, highly compact personal defense weapon choose this 7.5-inch configuration. It fits beautifully into discrete cases or vehicle bags while giving you rapid deployment capabilities and hard-hitting .30-caliber threat stopping metrics.
Hog and predator hunters running bulky reflex sights, night vision layouts, or wide thermal frames prefer side-charging platforms. The left-side handle clears the wide undersides of scope mounts, protecting hands from scrape damage during manual manipulation.
Enthusiasts who already run a .45 ACP handgun for self-defense select this complete kit to unify their ammunition requirements, allowing them to carry one class of common ammunition into the field or range lane to feed both firearms.
