The SwaggerTM Stalker QD42 is ready to stalk in any environment, any situation. The FlexreadyTM Technology allows you to swivel, slide, raise and lower your position as naturally as possible to give you mobility when it matters and steadiness when it counts. The legs adjust from 14" to 42" quickly to make shooting from the prone, seated, or standing positions easy. With Swagger Bipods, you will have maneuverability that is unmatched. Attach a Stalker QD42 directly to a picatinny rail or use the provided sling swivel adapter for use with bolt action rifles, muzzleloaders, crossbows or anything with a sling swivel stud on the bottom of the stock.
