It seems this weapon has no modern day counterpart (Strong primary attack/devastating secondary attack).
I still use it unless knockback is required (STF). The only weapon that comes close is the high density beam rifle but it is less damaging and has a knockbck which isn't always wanted.
Against single targets the TOS T3 is unmatched, it's time to get a modern day equivalent.
And there are so many times i wish i could use the Mk I weapons models on my Mk XI weapons.
Same here. I would not mind seeing this as a crafting option in the future... allowing us to take that MK I model and add components like scopes or power packs or whatever to them to bring them up to higher levels.
