F4 Defense Small Frame 308 - 6.5 Creedmoor

Leonardtown, Maryland – Veteran-owned F4 Defense, manufacturers of innovative small arms and accessories, announced the release of their small frame .308 and 6.5 Creedmoor (F4X) today in advance of the 2018 SHOT Show in Las Vegas. F4 Defense has been working alongside Remington® over the past year establishing a licensing agreement, utilizing the DPMS® Gen II patents, and incorporating them into a high-quality precision rifle. Furthermore, F4 has partnered with Proof Research® in the manufacturing of carbon fiber barrels, specific to the new F4X platform.

The F4X 6.5 Creedmoor and .308 Win will be on display at this year’s SHOT Show, Booth #N315, 3rd Floor on the NEXT Pavilion.

F4 Defense will initially release three variants of the F4X: 6.5 Creedmoor featuring a 22” Proof Research® carbon fiber barrel with CAMGAS system; .308 with 16” 1×8 Proof Research carbon fiber barrel; and .308 18” 1×10 Proof Research Stainless Steel Barrel. The F4X weighs in at roughly 7.5lbs.

The F4X was designed to fill a void in the hunting, competition, and LE/military markets. It’s the next step in the advancement of large caliber gas guns that vastly improves upon large frame AR-10s. The F4X is smaller, lighter, and just as accurate as any of the leading AR-10s currently on the market.

Each F4X comes standard with the Trigger Tech® Adaptable AR Primary Trigger and patent pending F4 Adaptive Rail System (ARS). The F4X features a flat-wire buffer spring, hydraulic buffer, and APA® Little Bastard™ Muzzle Brake. This combination results in a smooth and soft shooting rifle. Consistent with all F4 rifles, the F4X comes with a sub-moa guarantee.

You can see F4 Defense’s F4X and other innovative products at Booth #N315 on the NEXT Pavilion, 3rd Floor on the NEXT Pavilion at this month’s SHOT Show in Las Vegas, Nevada.
