Additionally, if you want to benefit from the range and accuracy the MV offers you want a decent sighting system and optimal ergonomics in holding steady and sighting it, which in turn points you towards a stand-alone grenade launcher rather than the under-barrel compromise.
Understand you mean that fire of 40mm MV ammunition would preferably be arranged using AG36 and similar UGLs attached to a specialized and well sighted stock or gripstock, and when UGL is alternately attached to a rifle or carbine it should be employed mostly to fire LV and only infrequently MV grenades. And of course if MV ammunition were procured for such use it would be in service when/if some type of MGL was procured later on.

Such a deliberate two step advance could well appeal to the British and in turn to others in ABCA. Usefully both types of UGL contending for attachment to the EF88/F90 are LV and MV compatible.
