Wiggle it - just a little bit.
Slightly disappointed in this product... it does what it's supposed to do but... in the extended position the lock has movement - only about a 1/2 mm but enought to feel it, especially with the stock fully extended.
I realise it's not meant for the precision shooter and when you have the rifle pulled in tight, you don't feel it... still, this otherwise useful adapter could be machined to remove that bit of movement.
