The Backbone of PENTAX's Precision Shooting Optics; All Pentax Precision Shooting Optics Have: HEAVY DUTY SPRINGS - Every PENTAX scope uses either a 14-pound coil spring or two 7-pound dual bias springs secured in the tube to prevent movement under recoil. These springs exert even counter-pressure for windage and elevation adjustments. LEAKPROOF "O" RINGS - All PENTAX riflescopes are filled with nitrogen gas and are double sealed with heavy-duty neoprene "O" rings providing a lifetime seal that makes your scope waterproof and fogproof. PRECISION MACHINED CLICK ASSEMBLY - Positive and repeatable finger adjustable windage and elevation click adjustments are easy to set and stay put after you set them. EXCEPTIONALLY THICK TUBE WALLS - Single-piece tubes, made from aircraft aluminum, have thicker walls than most scopes. EXTREMELY TOUGH RETICLES - Built and tested to withstand the heaviest recoil, PENTAX reticles are three times stronger than the industry standard. SUPER-HARD SCRATCH RESISTANT FINISHES - Outer tube surfaces are hard-anodized to prevent wear and scratches.
