Built this MK18 the way I wanted — compact, reliable, and set up for both iron-tight CQB and suppressed use. In this video I walk through every part I picked for the build, explain why I chose each accessory, and share what I’d change next time.
What I cover:
• Why I chose a Daniel Defense upper/rail for this MK18 platform
• Optics: EOTech holographic + magnifier combo — pros, cons, and mounting tips
• Unity Tactical riser & Unity mount choices for co-witness and quick transition
• SureFire mini Scout / SureFire weapon light overview — lumen choice and mount position
• CMC flat/curved trigger impressions and break feel
• B5 Systems furniture (grip/stock) for comfort and control
• Charging handle + QD sling setup
• Muzzle device considerations for running suppressors (legal & compatibility notes)
• Final thoughts: reliability, ergonomics, and what I’d upgrade

Amen!
Good looking gun man, I got something similar to yours and in my opinion best gun to own. That’s also just an overall do it all gun. I run my hot button a bit further back on the rail cause when I C clamp I rest my thumb on the grooves on the front side of the button. I’m soon to get a magnifier also.
So damn gorgeous!!! Bolt sounds sooooo smooth too!!!
My “mark 18” is a 10.5” lwrc m6ic a5…liked the short stroke piston system so much I bought 2…one of them has the a2 quad rail and the other is using lwrc’s proprietary handguard but they are my 2 favorites for sure.
nice rig
Huxwrx flow 556k is nice.
Nice looking gun 😊
Looks great, God bless.
