You will be able to collect up to 6 parts from your general post, 6 parts from individual posts and up to 3 parts by clicking on your friends' posts (in every 8 hours).
The DIY Weapons Lab is our newest limited-time-to-request-upgrade-parts New York City property! You have until 11:59 PM (Pacific Time) on Saturday 6/30 to upgrade it to its maximum potential by collecting parts through feeds/requests. The DIY Weapons Lab will retain the level to which you are able to upgrade it by the time the countdown timer reaches 0:00:00, after which the only way to upgrade the property will be by purchasing the remaining parts you need with RP.
The DIY Weapons Lab will allow you to craft some loot, including the Guerilla Fighter (144/104 +5 Attack at emerald level) as you upgrade the property with the help of your Mafia sending you upgrade parts!
