MCX upper on AR lower
Can an MCX upper be safely fired on a standard AR carbine lower without using the folding stock adapter? I.E., if I pulled the upper off my 6920 and put an MCX upper on, it won't explode or something on the first round? I was reading a thread on AR15.com about this "hybrid" combination where one user spoke against doing so without elaborating, but since the thread has been dead for two years, I doubt he's coming back to do so any time soon.

- https://www.thetruthaboutguns.com/gear-review-sig-sauer-mcx-stock-adapter-for-ar-15-receivers/ This appears to show a regular AR lower with MCX upper, appears to work as normal other than the regular AR buffer assembly doesn't do anything - as pointed out in the article too, the MCX has a taller receiver, but that rear section is already covered, just abruptly without an adapter.--AgentGumby (talk) 08:07, 11 May 2021 (EDT)
- Makes me wonder why the AR15.com poster left such an ominous warning. Spartan198 (talk) 11:57, 11 May 2021 (EDT)

New generation MCX
A third generation version of the MCX series is coming soon, as seen here (EDIT: video no longer available) and here. The weapon is lighter, and comes with a new handguard and latch system; it can now more easily use 7.62x39mm ammunition. The rear of the upper receiver also looks somewhat similar to the 1st gen MCX (as opposed to the 2nd gen VIRTUS). Some 3rd gen MCXes were previously displayed at DSEI 2021 (these can be seen at the end of this post), albeit with low profile deflectors like the MCX Rattler, instead of forward assists. There's also a newer version of the Rattler here. --Ultimate94ninja (talk) 10:03, 16 April 2022 (EDT)
