John Paul, owner of JP Enterprises, Inc., was kind enough to take some time with DefenseReview at SHOT Show 2009 and show us the JP LRP-07 Long Range Precision Rifle (LRPR) 7.62x51mm NATO (7.62mm NATO)/.308 Win. AR-10-type rifle/carbine with flip-out Left Side Charging System (LSCS), a left-side-situated charging/cocking handle. The JP Left-Side Charging System a very cool and interesting feature that provides superior ergonomics (for righties) to the traditional "T" charging handle since it allows for more leverage.
When not in use, the charging lever…
remains flat against the receiver via spring tension, similar to the TDI KRISS Super-V XSMG submachine gun’s charging handle. Lefties are on their own, until JP Enterprises decides to pull a Stag Arms and offer a lefty LRP-07. In the meantime, lefties will have to cant the LRP-07 to the left and charge the weapon by reaching over the top with their right hand, just like righties have to do with an AK-47/AKM.
According to Mr. Paul, the U.S. military Special Operations Forces (SOF) personnel who have spent time with the JP Left Side Charging System don’t want to go back to the traditional T charging handle, once they’ve acclimated to the new setup. You can operate the LSCS while maintaining a cheek weld, although DefenseReview isn’t sure when or why a military or law enforcement tactical operator would need to do this operationally, unless the bolt carrier group doesn’t lock back after the last shot. Since the LRP-07 features a left-side-situated bolt-carrier-release button, we have to assume the bolt carrier does lock back after the last shot. Still, the JP LSCS is pretty neat and worth checking out if you get a chance.
The JP LRP-07 Long Range Precision Rifle, itself, is pretty cool. It features JP’s .308 Low Mass Operating System (LMOS), which mitigates recoil, i.e. lowers the recoil impulse to the shooter, and allows for faster recovery between shots. The LRP-07 also features air-gauged, cryogenically treated JP Supermatch barrels to "ensure cold bore shot predictability, resistance to thermal drift on POA and exceptional life expectancy." 18-inch (18") lightweight, 22-inch (22") medium-contour, and 24-inch (24") heavy-contour barrels are available. The LRP-07 is also available in .260 Remington caliber, which comes with a 22-inch (22") medium-contour barrel with 1-in-8 (1:8) twist.
The LRP-07’s JP/VTAC modular hand guard features a Mil-Std-1913 "Picatinny" rail on top that mates with the upper receiver’s top rail, as well as a partial bottom rail towards the rear. The handguard utilizes an acentric barrel nut assembly, which allows JP to use a 2-inch (2") small-diameter tube, which JP claims makes a significant difference in the way the weapon handles. The LRP-07’s barrel actually sits slightly low in the hand guard to allow for the clearance of the AR-10 gas system (direct gas impingement system).
The whole purpose of the JP LRP-07 Long Range Precision Rifle is to provide operators with a large-frame 7.62mm/.308 AR-10-type rifle that handles like a small-frame 5.56mm NATO/.223 Rem. AR-15 rifle. JP Enterprises claims that the 18"-barreled lightweight-version for the LRP-07 weighs about the same as a 20"-barreled JP-15 or CTR-02 5.56, and is easy to handle and highly portable. The 18" lightweight LRP-07 rifle utilizes a mid-length gas system for improved reliability and less recoil "while still delivering nearly maximum velocity from the efficient 7.62×51 (.308 Win.) cartridge."
MSRP on the LRP-07 is listed as $3,199.00 USD.
Defense Review doesn’t yet know whether or not JP Enterprises will offer the Left-Side Charging System as an option on their JP-15/VTAC Rifle/Carbine series, but we’ll try to find out. The JP-15/VTAC Rifle with 16-inch (16") JP Supermatch barrel (thus making the weapon technically a JP-15/VTAC Carbine) looks pretty slick. The JP Enterprises website shows two different configs of the 16" carbine: 1) JP-15/VTAC Rifle with 16" Supermatch barrel, YHM Phantom flash suppressor, VTAC modular hand guard with 12:00 rifle rail, backup iron and EOTech 512, ACE SOCOM telescopic stock and M3 tactical light on right side forward, and 2) JP-15/VTAC Rifle with 16" J4 barrel and A2 sight pocket hand guard with YHM Phantom flash suppressor, VLTOR collapsible stock, optional OD green hand guard and 12:00 rail. JP also offers a "rollover" BUIS (Back-Up Iron Sight) system, which is interesting.
