PRO2A 7.5" 45 ACP 1/16 Pistol Caliber NR Side Charging Melonite M-LOK Upper Kit

Sub-Compact .45 Caliber Power Coupled with Stationary Side Cocking Ergonomics

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.

Key Features

  • Stationary Side-Charging Interface: The premium non-reciprocating left-side manual handle operates completely independently from the bolt carrier cycle. This allows for fluid charging from prone or tight vehicle positions and completely seals off the rear opening to block high-pressure gases and carbon debris from venting backward into your face.
  • Complete BCG Kit Inclusion: Takes the technical guesswork out of building a pistol caliber platform. This kit ships complete with a matching premium 45 ACP blowback bolt carrier group engineered to interface flawlessly with the side charging assembly for reliable chambering, extraction, and ignition paths. Comes with everything needed to complete a stripped lower receiver.
  • Authoritative .45 ACP Ballistics: Bring the proven stopping power of the heavy .45 Auto round into a highly stable, compact carbine format, tracking targets rapidly while maintaining excellent micro-footprint concealability.
  • Melonite/Nitride Barrel Protection: The heavy-duty 4150 CMV steel barrel is fully Nitride/Melonite treated inside and out. This premium chemical hardening vastly extends barrel life against rapid pressure wear, aids in uniform thermal dissipation, and counters harsh weather corrosion.
  • Slim Profile Free-Float M-LOK Rail: Built from durable 6061-T6 aluminum, the free-float handguard completely isolates barrel vibrations to preserve uniform mechanical accuracy while offering extensive M-LOK accessory attachment space and a top Picatinny rail.

Who Chooses This Upper Receiver Kit?

Sub-Concealable PDW & Backpack Builders

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.

Oversized Optics & Red Dot Operators

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.

Pistol & Carbine Logistics Unifiers

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.
