A method of forming a receiver 130 comprises arranging first structures 120a in a first set 117 and second structures 120b in a second set 119 such that the first structures 120a and the second structures 120b extend within an interior space 136 of the receiver 130 in a direction normal to a longitudinal central axis 112 of the interior space 136. The method further comprises indirectly bonding the first set 117 of the first structures 120a to the second set 119 of the second structures 120b.

A receiver comprises an interior space comprising a longitudinal central axis and a receiving end, a first set of first structures, and a second set of second structures. The first set of the first structures is positioned closer to the receiving end of the interior space than the second set of the second structures. The first set of the first structures has a first axial compliance coefficient along the longitudinal central axis of the interior space. The second set of the second structures has a second axial compliance coefficient along the longitudinal central axis of the interior space, such that the first axial compliance coefficient is greater than the second axial compliance coefficient.
