If the leg locks on your bipod are not working correctly try the following steps;
It's worth spending a couple of minutes to get these set up, as it speeds the process of adjusting & legs when in the field.
There are two types of leg lock design that have been used on the 'Javelin' & Blaser bipods. They will look like one of the examples below.
In the first image, the inner threaded (White) piece has been unscrewed (loosened) too far.
When attempts are made to lock the lower leg height the whole lower leg will continuously rotate without locking.
The reason for this is that the outer expansion piece (Green) relies on the taper of (White) piece being drawn down the threaded shaft to expand it so that it picks up on the inner surface of the upper leg until it is fully tightened against the inner surface of the upper leg, locking the height.
Some bipods had a similar (Black) locking piece that worked on a similar principle.
In the photos below you can see how this expansion works on the locking piece as a unit when they are set to create full expansion. (In this state the fitted would be too wide to reinstall back into the upper leg.)
And below show full expansion of the (Black) fitting.
To adjust these, unscrew the threaded 'knee joint' between the upper & lower legs, and remove the complete lower leg section from the upper leg.
Legs not running smoothly?
- Unscrew lower leg lock
- Clean leg lock mechanism of the lower leg
- Clean internal tube of upper leg and remove any debris or dirt (can be done with an old toothbrush & clean water)
Leg is not engaging & tightening correctly?
- Follow steps 1-3 above
- Hold onto the green (newer models / black on older models) Locking Piece and twist bottom of lower leg clockwise until there is a gap between the wedge and bolt of at least 1/8 inch or 3mm
- Place lower leg within the upper leg and screw up the lower leg lock.
Lower Legs pull completely out of the upper leg in normal use?
- Follow the procedure for 'Legs not running smoothly? ' above.
- With the lower leg removed check that the small red collet is present. This piece prevents the lower leg from coming all the way out of the upper leg. (This may be white on earlier bipods.)
- Take off the collet by gently prising apart an pushing it up the lower leg past the leg lock.
- Inspect the damage for wear or damage, make sure the thicker end is facing upwards (see below)
- Reattach the lower leg and leg lock
These collets are serviceable items and are available from us.
