    It isn't super visible in my pic but I'm running a VTAC LPSM right behind the front sight. It works okay. Allows me to get fairly far out on the forend with my support hand. I can still reach out and around the sling to activate the light.

    As mentioned I'd do it all different if starting over from scratch. But the rifle gets the job done. If and when I shoot the barrel out I'll go midlength with low pro.

    What about this? Not a full extension but it would allow a bit more real estate for sling swivels, etc.

    https://www.centurionarms.com/product-p/0609-cc.htm

    A Mossie rail could be added to get a light out farther on the gun.

    Mossie mounts installed on 11.5" guns:



    Centurion also has a Troy-ish style that telescopes out past the front sight:

    I have not used any Centurion parts but they are fairly well regarded from what I've seen on the web.

    The Centurion rail is awesome but it requires cutting off or otherwise removing the delta ring so it would be a no go based on the OPs requirements. The Troy Charlie rail (drop in 1913 FSB) is a truce drop in like the delta.

    From the description on Sampson’s site:

    It will require removal of the bayonet lug and sling swivel.
    The sling swivel and bayonet lug are the reason the little 1913 rail portion is where it is on the Troy Delta.

    Those 11.5” with the ACOG and offset BUIS are a neat set up.

    Not ideal but they work OK for 1990's tech.

    We got a couple thousand surplus ACOG scopes from the Marine Corps. The barrels are actually surplus too. They came from DoD and were cut to 11.5" by your associates in Altoona.

    The offsets are a fairly new addition to our authorized equipment list. One of the continued complaints about the ACOG was using them at the 15 and 7 yard line portions of our qual. The offsets help in this regard.

    I have one of those cut down SOCOM barrels on my work rifle. They shoot great. Altoona also opens up the gas ports to .070”. If you can’t have a free float the heavy barrel is the next best thing.

    Offset RDS >offset BUIS but if you had tons of Aimpoint micros floating around you probably wouldn’t be running surplus ACOGs.

    How are those Mossie mounted WML holding upon the 11.5” right over the muzzle device ?

    We have a mix of SOCOM and older M4 profile cut downs. The two rifles pictured here have the lighter profile. Weight with sling and empty mag is pretty close to 8.5 pounds.

    The lights are holding up fine. The finish gets a little blemished but the glass stays clean. Down side is pulling the light off to change batteries. But that isn't any different than what's required with the pistol.

    That is my old setup brother.

    I ran a Kley Zion mossie clone with nary an issue and a 600 lumen x300 for two years. Solid setup along with the magpul moe SL handguard.

    The impetus for the change was that I wanted to attempt to free float the barrel, cover the exposed barrel in front of the front sight block and open up some lighting options via the addition of mlok.

    Ive got this UTG rail on the gun and while its not bad, its just not right. Kind of like porridge that is too hot or too cold....lol.

    Im still working on the writeup and pics. Give me a day or two.

    PS, the centurion rail that you linked that extends underneath the FSB Is EXACTLY what im looking for with my aforementioned criteria. I just dont think anyone makes it.

    Options may have existed other than the Troy but I assume what may have been out there is probably discontinued. Market demand for carbine gas A-frame rails has got to be almost nil nowadays.
