Investigators in the Netherlands have briefed relatives of their findings, including playing taped phone calls of those involved in launching it.
CNN's Phil Black said: "Through examining social media posts, that's video pictures intercepted phone calls and witness accounts this investigation says it has accumulated a vast amount of evidence."
All 298 people on board the Boeing 777 died when it broke apart in mid-air, flying from Amsterdam to Kuala Lumpur.
Families have been told it's now known for sure the missile was fired from territory held by Russian-backed rebels.
It was fired from a farmer's field.
Russia's consistently rubbished allegations rebels fired the missile, suggesting instead the plane was brought down by the Ukrainian military.
The Telegraph's Moscow correspondent Roland Oliphant told Rachel Smalley Russia's response has not been surprising.
"They have said that they believe this investigation is biased, that it's politically motivated. The Ministry of Defence has reiterated its denial that Russian air defence units ever crossed the border."
Moscow has vetoed attempts in the UN to prosecute those involved at a war crimes tribunal.
Mr Oliphant said it's not clear how, or if, anyone will be prosecuted.
"Russia vetoed the creation of a special tribunal into this so we don't even know what kind of court evidence could be submitted to. We don't think Russia's going to give up the operators or the commanders of that weapon."
Aviation lawyer Jerry Skinner is behind a push for compensation that includes the widow of New Zealander Rob Ayley.
He told Rachel Smalley it's time for Russia to come to the table.
"What happened today was a factual confirmation of their participation. We are inviting them to sit down and talk with us."
He said the new findings have great weight, and back their case.
"And it will submitted to court as further support to our allegations.We're hopeful that either the Russians will choose to respond or if they don't that the court will move ahead with the case without them."
