Rifle length handguard...

[black2002ls]

Buy a low profile gas block that uses set screws to run your carbine gas tube.

Push A2 sight to the front, take it to MGS and have them drill the barrel in the new rifle length location.

I guess the A2 isn't simply held in by the tension of the roll pins? Cost location?

The rub is, what is the barrel profile? It has to be the same diameter at the front where the A2 FSB will sit as it was in the carbine position.

It is pretty simple to do. I built a 16" mid length gas gun with A2 FSB and rifle length MOE. Very fun gun to shoot with the long sight radius.

The A2 will be held in by either a tapper or straight pin. Most factory installed FSB will use a solid pin not a roll type. You need to verify before you try to punch them through so you know which way to hammer. All the ones that I have punched off, I have had to heat the block with a mini torch and use a BFH. Once you move the pin the slightest they will push right through. But that first budge can be a bitch.

Military Gun Supply over off of 820 near E Berry. Cost about $40-50.

You can measure the barrel diameter. Let me find my old thread and get the numbers. I want to say you will find it to be .730"+/-.010. If it is smaller than that it isn't gonna work without some sort of shims.

I have a rifle length UTG quadrail for triangle end caps I need to get rid of.

FWIW I would get a $100 free float rail from red x, low pro gas block, and a set of magpul flip up sights. Troy and other companies make free float rails that use a factory barrel nut if you dont want to swap it.

I want to try and keep this a budget minded rifle. Looking around, it would be nice to find a clamp style front sight block. Would save having to have the barrel drilled.
