It locks up solid and will locate the buffer tube to the upper, bypassing the need to screw the buffer tube into the lower.

For those of you wondering what this is, this is an attempt to build a thumbhole stock for an AR out of plastic bricks, such as Lego or Mega Bloks. Why a thumbhole stock? Why, to reinforce the AR lower built out of plastic bricks, of course ; )
