JP LRI-20™ Semi-Monolithic Long Range Precision Rifle

Whether for long-range competition or sniper duty, the LRI-20™ upper receiver offers the most stable, repeatable platform for a precision gas gun on the market today. The core of this design is the new integral hand guard nut, which counters the weak point of standard AR design by adding an abundance of material to stabilize the barrel mount. Supporting this, we’ve also added extra material to the front pivot pin joint. Paired with our MicroFit Takedown Pins, the LRI-20™ offers a 100% unified chassis system that we’ve seen tighten groups on even the “problems children” of our barrel sample library.

Patterned on our lightened military-style upper design, the LRI-20™ includes both dust cover and forward assist paired with our dedicated side-charging handle. The integral nut design works with any iteration of our MK III hand guard tubes. Like all our recent receiver designs, this nut is also internally undersized for a mandatory Thermo-Fit™ installation that produces an unshakeable fusion between barrel and receiver.

LRI-20™ upper assemblies are available to pair with any existing LRP-07™ side-charge lower. Complete rifles are available either as ready-to-ship Ready Rifles or custom spec’d from our complete lineup of components and options in our online Rifle Builder.
