Ruger Precision Rifle Gen 3 .308 Winchester Bolt Action The Ruger Precision Rifle is a highly configurable, in-line-recoil rifle with the kind of sub-MOA accuracy that puts more expensive rifles to shame. Every component has been carefully considered and precisely engineereda |from the Multi-Mag Interface that accepts a number of different magazine styles, to the cold hammer-forged barrel, to the Marksman Adjustable trigger. The Gen 3 version takes all the excellence of the Gen 2-and make just a few tweaks. First, the old KeyMod handguard has been replaced with a new lower-profile M-Lok handguard that gives you just a little more scope clearance for big optics-so if you prefer M-Lok, this is a nice change. The second improvement is a black nitride finish on the bolt, which replaces the stainless finish on the Gen 2 bolt. These aren't groundbreaking changes by any means, but why overhaul a good thing? Bottom line: it's still the RPR you know and love, but with a few shrewd improvements based on feedback from competitive shooters. New for the Gen 3: New lower-profile free-float handguard with M-Lok slots rather than KeyMod slots Black nitride finished bolt Barrel: Highly accurate 20 inch Ruger cold hammer-forged 4140 chrome-moly steel barrel with 5R Rifling at minimum bore and groove dimensions, minimum headspace and centralized chamber Medium contour (.75'' at the muzzle) barrel, with 5/8''-24 threads.
