Description
The 6.5 Creedmoor has earned its reputation as one of the flattest-shooting, most forgiving cartridges you can run through a big-frame AR, and the Rock River Arms LAR-BT3 Predator HP was built to squeeze every bit of that potential out of it. The heart of the rifle is a 20 inch fluted stainless steel barrel with a 1:8 twist that stabilizes the long, high-BC bullets the Creedmoor is known for. Rock River cryogenically treats the barrel to relieve stress in the steel, which pays off in consistency and barrel life over the long haul. The fluting trims weight without giving up rigidity, and the muzzle wears an RRA Operator brake on 5/8×24 threads to keep recoil and muzzle rise in check for quick follow-ups.
Billet Receivers Give the Predator HP a Rock-Solid Foundation
Instead of standard forged parts, the LAR-BT3 rides on Rock River's billet upper and lower receiver set, machined from aluminum for a tight, rigid fit that helps accuracy stay consistent shot after shot. A rifle-length gas system with a low-profile gas block keeps the action cycling smoothly, and the low-profile block tucks neatly under the 17 inch free-float handguard. That handguard gives you M-LOK slots for bipods, sling mounts, and lights, plus a full-length top rail with plenty of room for a magnified optic, which you will want since the rifle ships without sights.
Set Up for Real Trigger Time
The RRA two-stage trigger is one of the better factory triggers in this class, with a light takeup and a clean break that makes precise shots easier to pull off. A Hogue rubber pistol grip and the six-position Operator CAR stock let you dial in length of pull for prone, bench, or blind. The oversized winter trigger guard is a nice touch for cold-weather predator hunts when gloves are non-negotiable.
Where the LAR-BT3 Predator HP Earns Its Keep
At 9.2 pounds with a 39.7 inch overall length and a 20 plus 1 capacity, this rifle is right at home calling coyotes, stretching steel past 800 yards, or filling a deer tag. It is a lot of precision rifle in a semi-auto package, and it comes from a company that has been building ARs the right way for decades.

Frequently Asked Questions
Does the LAR-BT3 Predator HP come with sights or an optic?
No, this rifle ships without iron sights or an optic. The full-length top rail on the receiver and 17 inch handguard gives you a long, uninterrupted mounting surface, so plan on adding a quality magnified scope to take advantage of the 6.5 Creedmoor's long-range capability.
Is the 20 inch barrel enough to get the most out of 6.5 Creedmoor?
Yes, a 20 inch barrel is a sweet spot for this cartridge in a semi-auto. You give up a modest amount of velocity compared to a 24 inch tube, but you gain a handier, better-balanced rifle for field use, and the 1:8 twist stabilizes heavy match and hunting bullets just fine. Most factory 140 grain loads still carry plenty of energy well past typical hunting distances.
What is the LAR-BT3 Predator HP best suited for?
This rifle was built with predator and varmint hunting in mind, and it doubles nicely as a long-range target gun. The cryo-treated match barrel, two-stage trigger, and rigid billet receivers make it accurate enough for steel and paper at distance, while the oversized trigger guard and adjustable stock make it practical for cold-weather coyote sets. It also has more than enough punch for deer-sized game.
Will standard AR-10 or SR-25 pattern magazines work in this rifle?
The rifle ships with a 20-round metal magazine, and Rock River's BT3 platform is built around common .308-frame magazine patterns, so SR-25 style magazines are generally what you want. As with any large-frame AR, it is smart to test a magazine brand with your rifle before stocking up, since AR-10 pattern rifles vary more between manufacturers than AR-15s do.
