Just my general feedback on loot during this event and for future events I guess?:
The declaration grips, upper receivers and shield sections are about as rare as the patriot parts, which as a non-DMU user is not too rare but certainly not enough to gather 100. I played at least once each day of the event and at the end of it, excluding uncrates never even got close to 100 patriot parts.
Make event components drop in higher quantities, I only ever get 1 or x2 patriot parts every time I find them during scavenge missions. They're sort of uncommon so at the end of the event I only managed to gather about 40 parts. :/
Going on from the first point, please don't put the unlock options for the event crates for items like the declaration grips, receivers and shield sections (i.e parts that only require 1 of to craft the required item), because they feel more like a massive waste compared to the other items from the crates.
