this is the Colt IAR that Singapore uses right
where do you even get one of these uppers

i was obsessed with Red Right Hands IAR with heat sink until i saw a meltdown video where the heatsink just melted out and poured molten aluminum all over the handguard and table

these heatsinks look alot more reliable (although i wonder how much the upper weighs)
i would like to see a meltdown video done on these and see how well they hold up and at what roundcount they start failing

the Red Right Hand IAR failed before normal HBAR ARs (700 rounds before the BRN-4 which this channel has as its highest round count at over 1700 rounds)
