PRO2A 16" 5.56 NATO 1/7 Melonite M-LOK AR-15 Upper with Flash Can Kit

Product Overview

The PRO2A 16" 5.56 NATO 1/7 Melonite M-LOK AR-15 Upper with Flash Can Kit delivers a robust, all-in-one upgrade solution designed to streamline your custom rifle build while optimizing muzzle blast control. Chambered in the ubiquitous 5.56 NATO cartridge, this complete performance package includes a 16-inch barrel shielded with an ultra-durable QPQ Melonite coating. To significantly enhance operator comfort, this model integrates a project-forward linear Flash Can device neatly tucked beneath the free-float rail. Eliminating procurement guesswork, this comprehensive build package comes complete with a Mil-Spec Bolt Carrier Group (BCG), lower parts kit, charging handle, and a 6-position adjustable rifle stock assembly.

Key Features

Linear Flash Can Muzzle Device: Tames muzzle blast by forcefully routing concussive sound waves, thermal expanding gases, and visual flash signature straight downrange and away from the operator.
All-In-One Hardware Integration: Consolidates your firearm assembly by packing a premium mil-spec lower parts kit, a complete standard BCG, charging handle, and an adjustable stock and buffer tube system under a single part number.
Full 16-Inch Legal Rifle Profile: Squeezes complete powder burn efficiency out of the 5.56 NATO cartridge while bypassing the legal tax stamp and registration restrictions of an NFA short-barreled rifle (SBR).
QPQ Melonite Hardened Protection: Premium Salt Bath Nitride finish hardens the internal rifling and external steel surfaces against friction wear, intense thermal transfer, and field environmental humidity.
Fast 1/7 Twist Rifling: Precision-rifled profile engineered to provide exceptional rotational stabilization for heavy grain tactical and mil-spec projectiles (62gr, 69gr, and 77gr).
Free-Float Slim M-LOK Handguard: Enhances intrinsic accuracy by isolating barrel harmonics while supplying a continuous top rail and modular accessory slots (extended to partially shroud the Flash Can).

Why Choose This Product?

Piecing together an AR-15 rifle from scratch often leads to a web of part compatibility headaches, timing struggles, and independent component shipping fees. The PRO2A 16" 5.56 NATO Upper Kit completely eliminates this barrier. By grouping a premium, pre-headspaced upper receiver directly with a mil-spec M16 bolt carrier group, full lower internals, and an adjustable stock setup, this complete bundle delivers a verified out-of-the-box build experience with zero assembly guesswork.Beyond its convenience, this kit is structurally designed to handle intense environmental wear and harsh operational conditions. Traditional standard muzzle devices vent concussive blast laterally, causing severe acoustic discomfort at indoor ranges or out in tight field blinds. This layout integrates an advanced project-forward linear flash can to force concussive pressure straight downrange away from your ears. Backed by heavy-duty 4150 steel construction, an ultra-durable Melonite finish, and a fast 1/7 twist rate built to stabilize everything from common range ammo to heavy duty rounds, this comprehensive package strips away build complications to give you a clean-cycling, soft-concussion rifle powerhouse straight out of the box.
