Upgraded my older cmmg handguard - 7" with keymod - CMMG, Inc AR-15 Handguard Kit

I have a CMMG carbine piston upper. I've had it for several years and wanted to upgrade the handguard to an m-lok version. I'm glad I did, the replacement handguard has a better anodized black finish that is darker than my current one (dark grayish). It also has a better barrel nut that it attaches to. My current barrel nut looked like the one pictured with the handguard, but the newer barrel nut that was received has a groove in it and comes with a metal tab that is installed with the handguard screws and keeps the handguard from sliding forward. Overall, a nice improvement over the previous version of the handguard.
