The Allen Helix Bipod (Model 5201) is a mechanical rifle rest engineered for factory-stocked rifles equipped with a standard sling swivel stud. Constructed from a hybrid blend of aircraft-grade aluminum and reinforced nylon polymer, the unit provides a rigid forward rest for prone shooting and benchrest target work. It mounts directly to standard rifle swivel studs without the need for Picatinny or M-LOK rail adapters, fitting native hunting platforms such as Howa 1500, Lithgow Arms LA101/LA102, Ruger American, and Tikka T3x rifles.

Who is the Allen Helix Bipod 9 - 12" Swivel Stud for?

• Prone and benchrest target shooters — attaches directly to factory-stocked rifles with swivel studs to deliver an 8.5 in to 11.5 in height adjustment range across 4 indexed settings for stable positional shooting.
• Field varmint and big-game hunters — provides rapid mechanical deployment in the field with a 1.155 lbs overall weight and 180° ARC leg adjustments across 5 locking angles to adapt to uneven natural ground.

Less suitable for: Modern tactical chassis requiring direct M-LOK or Picatinny attachment, shooters requiring lateral canting or levelling on uneven slopes (who require a dedicated tilt-capable swivel stud bipod), or hunters shooting over tall grass and scrub in seated positions (who require taller 13-inch to 27-inch bipods or dedicated shooting sticks).
