Can you maybe add a piece that closes that floating gap? As in 90 degrees piece down to touch the barrel so if the guard is pressed down it does move, I feel like that could strengthen and stabilize it. My only concern is that without it it will eventually wiggle in the front. 

There will always be movement with all the components up there (barrel, mag tube etc).  It is very stiff, I’ve been testing with a 2 cell weapon light, and have had no issues with the front touching the barrel.

it is 1/8” thick…

Love the color of your gun, mine is blue but lighter, yours is the perfect blue. Lucky!

this particular receiver is an older gun from around 2013 or so I believe (still has the aluminum trigger assembly), I have a couple other M4s and to be honest I just shoot em and I haven't even looked at the colour of the receiver hue 🤷‍♂️

Thanks!  I’ve been asked about the SBS.  I haven’t looked at the mlok spacing, and I don’t have a 14” barrel to test out as that is illegal in Canada (14” barrel semi auto).

chances are slim… 

however, it might be possible to hack off some front slots with a good aluminum cut off blade, and debur and then do a touch up annodizing kit on it.

m4 barrel is 18.5 inch, so I guess the SBS would need a heat shield that is 4.5” less. Just measured and you’d lose the front 3 slots.

maybe I’ll try to make a few during the production run and I’ll send one off to someone to test… :)

I'd certainly be interested in a SBS version

How about a video demo on your YouTube channel?

There will be some videos this summer from YouTubers.  I’ll post links when they are up.

So to use this heat shield I could not retain the oem optic rail?

I’ll be selling a true mil spec picatinny rail to replace it and provide compatibility with the heatshield.
