GRIFFIN MK1 Rifle Patrol 5.56 NATO 16" Barrel Tactical Firearm

The Griffin MK1 Rifle Patrol is a 5.56 NATO carbine purpose-built for shooters who need a reliable, unfussy rifle that works right out of the box. Chambered in 5.56 NATO with a 16-inch barrel, this tactical rifle cuts through the marketing noise and delivers genuine capability—whether you're running drills at the range, training for precision work, or deploying it as a dependable patrol or duty platform. Griffin Armament engineered the MK1 series around a simple philosophy: include what works, leave out what doesn't. You get a carbine that runs suppressed or unsuppressed, with a gas system tuned for soft, predictable recoil and an overall weight of 7 pounds that won't wear you out during long days in the field.

Every component on the MK1 Patrol comes from Griffin. The 416R stainless steel barrel is paired with Griffin's enhanced bolt carrier group, forged upper and lower receivers with Type 3 hardcoat anodizing, and an ambidextrous safety selector and charging handle (the SN-ACH is specifically optimized for suppressor use). The fire control features Griffin's A3 grip and enhanced trigger guard, while the buffer system and receiver extension are designed to normalize the gun's behavior when running a suppressor. You'll also find a low-profile rail system, RailShield panel set for heat and snag management, a pinned Primo gas block, and Griffin's silencer mount muzzle device.

This isn't a tricked-out race gun or a minimalist budget build—it's a thinking shooter's rifle that handles the work you actually do. The combination of suppressor-optimized tuning, quality internal components, and thoughtful ergonomic touches means you spend less time troubleshooting and more time shooting. If you're looking for a 5.56 tactical rifle that pairs reliability with no-nonsense design, the Griffin MK1 Patrol deserves a close look.
