Not wholly Incorrect but..
Our Gen 3 versions do not have the chrome hammer forged barrel due to export issues m+m are having. They can’t make the 18.6 and 12.5 in that, yet.. they said they might
The rest is correct
They make an “M” series and a “plus” series
Both are “gen 3”
Now, they also said any new rifles they send out will have all the gen 3 internal upgrades also
Even if yours doesn’t have the lighter weight handguard and chrome barrel (making it an m series)
