Measuring 45.25–48.75” long depending on the length of pull of the adjustable, folding Ruger Precision MSR stock, the RPR is built on a 4140 chrome-moly steel receiver with heavy-contour 26” stainless steel barrel topped with an APA Muzzle Brake. Surrounding the barrel is a newly designed free-float aluminum handguard with flat bottom, M-LOK slots and integrated 1.50" dovetail for common tripod mounts and other QD accessories. A 20 MOA Picatinny rail atop the receiver offers sufficient real estate and eye relief for mounting even the largest of optics.

Other new Custom Shop model features include a flared magazine well for improved loading of the two provided 10-round Magpul PMAG magazines and optional red barrier stop, screwed into the front of the mag well. The factory-installed flat-face TriggerTech Trigger and ambidextrous manual safety are also finished in a red anodizing. In total, the RPR weighs in at 12.8 lbs.
