Ruger 8405 Precision Rimfire, .22 Wmr, 18 inch, 9+1, Hardcoat Anodized

The Ruger 8405 Precision Rimfire brings the Ruger Precision Rimfire series into .22 WMR with a bolt-action platform built for serious rimfire work, offering an 18" cold hammer-forged 1137 alloy steel barrel with 1:14" twist and 1/2"-28 threading for muzzle devices or suppressed shooting, a hard black anodized 15" free-float handguard with Magpul M-LOK slots, and an anodized 0 MOA Picatinny rail so optics mount and zero quickly. Its molded one-piece glass-filled nylon chassis and Quick-Fit adjustable Precision Rimfire stock provide repeatable length of pull and comb-height settings, a flat Picatinny bag rider and QD sling pocket for stable prone or bench positions, and indicating marks to return to favored setups—advantages for precision training, competition rimfire matches, or small-game hunting. The Big-Gun bolt throw option, oversized bolt handle, Ruger Marksman Adjustable trigger, and AR-pattern grip and safety deliver familiar controls and tunable trigger pull for shooters transitioning from centerfire rigs, while accepting Ruger magnum rimfire magazines and weighing about 6.8 lb for a balanced carry and follow-up shot capability.
