Have you done much night shooting with the light?  Unlike most folks here I would recommend not mounting a light at 12:00, because after you fire a couple rounds the light will illuminate the gunsmoke to the point that you will have difficulty seeing your target.  With the light at 6:00 the muzzle will cast a shadow in the gas cloud that will allow you to see through it easily.  You just need to get the light closer to the muzzle to reduce the shadow.  I would get a 13"-15" free float handguard that the suppressor will fit inside of.

Use a Gear Sector 6P mount and mount it on the top rail with the light to the right side of the rail.  Should mount up high enough to cast the shadow down to the 7-8 Oclock position.

They come up on the EE quite a bit for $30-40 shipped.

Both of these rifles use the Surefire 6P lights and are mounted to the top of the rail with the light offset to the right side.  They are out of my field of view through my red dots.

Mount another light on the opposite side. ILLUMINATE ALL THE THINGS

get a shorter Can, USE NVG's and you wont need or care much about the pattern of the light as yu ought to be using an IR illuminator or get a longer rail or get a PEQ 15 and use the IR illuminator and ditch the surefire

You should be moving to a different spot after a brief use of the light. Not standing in one place with the light on and emptying a magazine.

 




 

I took a thorntail off a seldom used AR and swapped it over to the SBR that is only ran suppressed.  A simple solution to a trivial issue.

IWC Thorntail mount.
