A full-length upper receiver change looks really appealing now.
IMO if you're saying that in response to the torch being mounted clamped to the barrel (i.e.: insufficient handguard length), I think the long version of the free floated handguard upgrade posted before (most recently in posts 2964/2965) is perfectly fine, even if it does have a front cutout for the adjustable gas regulator.
That said I do also think a full upper receiver upgrade kit for SOF could be useful as well where more changes can be made perhaps to the barrel to have a slightly heavier profile, and also removal of the rear iron sight, making the gas regulator lower profile to enable a continuous upper rail etc.
The rear iron sight is part of the lower receiver. Will probably need to change the entire receiver if we want to remove it. Probably a good time by then to make more changes and introduce it as a Gen 2 version of the rifle.
Thanks for the correction, I remembered incorrectly. I still want to remove that stump on the rear sight and make everything flat.
Yeah, and that can be done by just having a new upper receiver overall.
The rear sight bump can be made probably equally flat to the height of the pic rail, based on the position of the takedown pin.
Why do you want to make it flat? I can see scopes can be mounted slightly closer to the barrel if you remove the front sight as well. For a rifle like this, potential error increase from the slightly higher offset is small relative to the accruacy of the weapon (this rifle probably has 2-3 MOA accuracy). A military rifle should always have an iron sight and if you make it flat you'd need an add-on rear sight (there may not be room for a recessed popup sight), probably not as sturdy/durable, judging from my AR experience.
