Is the HK416D a V2 or V3 LDT gearbox?

As the title says is HK416D a V2 or V3 LDT gearbox?, looking to buy a 2nd one and start modding it so i have a backup

Just bought one

Thats actually what i was looking at hahaha

That does not look like a V3 gearbox to me.
V3 gearboxes have a spot to mount a motor cage like a gen8

Ldt boxes are different then standard ones


I think the “V3” means version 3 of that particular Warinterest box.
I have a version 2 one which I put in a Wells receiver. It does not have the quick change spring feature.
