The MCR has a last round hold open but as mentioned above it's magazine activated with no external release. That being said... It is REALLY simple to engage it through the empty magwell with your index finger and then just use the slingshot method to release the bolt. With the charging handle being so easy to swap left/right side you can set it up to which ever makes it more comfortable for you to use this way.
Edit: Looking at the External Bolt Catch Release that Kodiak sells it looks like it would probably work on the MCR... possibly with some slight modding, i think.
