Both the upper and lower receivers are billet machined from 7075-T6 aircraft-grade aluminum alloy, but their shapes and integrally machined features are very different from other AR-10 style rifles. The upper—called the POF M.R.R. (Modular Railed Receiver)—is machined flat on top down to only 1/4” above the ejection port to accommodate the company’s monolithic handguard/top rail system which is made up of two pieces: the reinforced “backbone” receiver to which the barrel is attached, plus a second top piece that includes a free-floating, monolithic handguard/quad rail system. This design removes stress form the bolt area, eliminates receiver flex and strengthens the entire upper receiver. Machined integrally with the one-piece hand-guard is a 22-slot Picatinny top rail, with a 5-slot Pic top rail all the way forward. In between the two integral rail sections is a 7-inch long flat that is drilled and tapped to accept additional rail sections to create a continuous top rail. Flats along the handguard at the 3, 6 and 9 o’clock positions are drilled and tapped to accept as many optional 5-, 12- or 17-slot rail sections as you care to install.

The P308’s modular handguard allows you to pilfer rail sections from up top and attach where needed.

The bolt carrier is machined from 8620 steel and nickel-boron coated. It houses the bolt, extractor and firing pin—all of which are hard-chrome plated—as well as a POF designed cam pin with a novel, NP3-coated roller head that glides along in its channel, enhancing reliability and prolonging receiver life.

The lower receiver features a wide, heavy, integrally machined trigger guard with an oversize opening, and a mag well that is dramatically flared to aid in magazine insertion under stress. Controls are fully ambidextrous, with a safety selector, bolt release and mag release on both sides of the lower. A bolt hold-open lever is positioned in the front edge of the trigger guard and is reachable by the trigger finger. The trigger is a non-adjustable, single-stage, POF design that is among the very best single-stage AR triggers we’ve tested: zero take-up, zero creep, zero stacking and a crisp break at an average pull weight of 3 lbs. 3 oz. The trigger and hammer are secured by KNS Precision stainless steel, non-rotating, anti-walk pins specifically designed for the POF ambidextrous lower receiver.

The P308 is fitted with a Magpul STR 7-position collapsible buttstock mounted on a POF-designed anti-tilt buffer tube that prevents carrier tilt. It also comes with a Magpul MOE pistol grip and one 20-round Magpul magazine. Overall length measures 33.25” with the stock collapsed; 37.25” with it fully extended.

When precision and reliability are integrated into a compact package, you have a rifle that will excel in any type of defensive or offensive role you task it with.

Function and reliability testing was conducted using a Burris Skulltac Combo, which includes a Skulltac 1-4x24mm illuminated-reticle riflescope, Burris P.E.P.R. mount with integral rings and a Burris Fast Fire III reflex sight mounted atop the rear ring. The P308 put fifty rounds on steel  without a failure of any type.

Switching to a Burris 4.5-14×42 AR 7.62 riflescope mounted on the top rail, accuracy testing from the bench at 100 yards revealed a rifle with some serious precision potential. The P308 showed a real preference for Black Hills’ 168-grain Match BTHPs, with a best 3-shot group measuring 0.68” center to center, and the rest all printing under 1 MOA. Hornady 155-grain TAP FPD was a close second, with a best 3-shot group of 0.93”.

The P308 comes with a 100% satisfaction guarantee and a 3-year limited warranty. See it at your firearms retailer, or contact Patriot Ordnance Factory, Dept. OT;
