The original Harris bipod model BRM with a 6-stage detent for quick height adjustment and to compensate for uneven floors. The height lock takes place via a push button for each leg. The feet are approx. 15 cm long when retracted and 23 cm when extended.
The bipod can be attached to most weapons without any problems and without additional tools on the weapon's own sling swivel bases (fitted at the factory on almost all US weapons).
