Patriot Ordnance Factory® P300 .300 Win. Mag. Semi-auto AR-10 Rifle

You can't argue the hard-hitting power of the .300 Win. Mag., but the major issue plaguing the semi-auto win mag market is the sheer size and weight of the platform. POF® set out to address that. Doing what they do best—careful engineering and relentless testing—POF condensed this .300 Win. Mag. package to a size of an AR-10.

The P300 is built around the Gen 4 billet lower receiver, and features a number of innovations to improve handling and shooting. The addition of the adjustable gas piston system lets you tune the rifle to optimum performance based on your load and rifle configuration. The single-stage Enhanced Finger Placement trigger naturally guides the tip of your finger to the same resting place for a precise, smooth, consistent trigger pull every single time. And because proper gas regulation and a nice trigger are nothing without the precision and durability of a quality barrel, the P300 features a precision-machined, fluted, nitride heat-treated barrel for MOA accuracy.

  • Built on the completely ambidextrous Gen 4 billet lower receiver
  • Nitride heat-treated 24" chrome alloy barrel is precision-machined for absolute accuracy
  • POF gas system allows the user to restrict, and even shut off, this extra back pressure by simply rotating the gas plug
  • Enhanced Finger Placement single-stage 4-lb. trigger naturally guides the tip of your finger to the same resting place every time
  • Oversized heat sink barrel nut delivers 17 times more heat dissipation than a standard AR, and adds significant rigidity to the overall platform
  • E2 dual-extraction technology allows gas pressure to assist the extractor
  • Oversized triple port muzzle brake helps fight muzzle rise
  • One piece high phosphate nickel-coated bolt carrier design helps reduce carrier tilt
  • Roller cam pin reduces friction and drag in the action
  • MRR Modular Railed Receiver is a two-piece system (receiver and handguard): the free-floating handguard slides directly onto the upper's "backbone," keeping weight of accessories off the barrel
  • POF ambidextrous QD endplate
  • POF Tomahawk ambidextrous charging handle
  • Made in the USA with components and materials sourced from American companies
  • Includes one 14-rd. magazine
