P2A PATRIOT 16" 5.56 NATO 1/7 Melonite M-LOK Rifle with Flash Can

Product Description

Maximize your tactical performance, operational control, and downrange stability with an aggressively styled, completely assembled centerfire platform. The P2A PATRIOT 16" 5.56 NATO Melonite Rifle with Flash Can is meticulously engineered to combine full-length 16-inch ballistic velocity with a signature recessed forward-directed blast profile. Built around a matching set of mil-spec forged 7075-T6 aluminum receivers, this turn-key firearm system uses an exact-spec 1:7 twist barrel optimized to stabilize heavy-weight tactical projectiles from 62gr up to 77gr duty ammo under intense operational heat. The barrel and its integrated linear flash can are cleanly enclosed inside an extended 17-inch free-floating M-LOK handguard. This configurations drives blast acoustics, concussive energy, and burning carbon completely forward downrange away from the shooter, delivering extensive modular real estate for optics layouts, tactical weapon lights, or hand stops while optimizing comfort during firing loops.

Key Features

  • Clean Recessed Flash Can Aesthetics: Integrated extended linear flash can sits cleanly inside a longer 15-inch handguard profile, directing operational sound, gaseous residue, and concussive shock waves straight downrange away from the shooter's line of sight.
  • Versatile 1:7 Tactical Twist Profile: Heavy stabilization twist rate engineered specifically to track heavy military and defensive bullet variations with ultimate structural accuracy over extended distances.
  • Resilient Free-Float M-LOK Architecture: Premium slim profile aluminum rail isolates the barrel from external handling pressure vectors, ensuring continuous point-of-impact accuracy.
  • Liquid Bath Nitride Hardening: The 4150 Chrome Moly Vanadium steel core features full interior and exterior QPQ Melonite coating to offer absolute weatherproofing and prolonged bore precision under severe firing loops.
  • 100% Sourced & Assembled in the USA: Sourced and built to tight manufacturing metrics in Georgia, backed completely by premium custom-shop engineering quality parameters.
