Clamp-on FSB?

[rob_s]

I'm certain I've seen them somewhere before. I'm looking for a clamp-on FSB for a 9mm barrel I have. Nothing fancy or flippy, just a stock-style FSB that clamps instead of pins. Bayo lug not an issue.

So you finally gave in and did a pistol cal?

I think Armalite uses a clamp on FSB on some of thier models.

I've had a 9mm Colt since 2007.

Here's a link to the armalite one.

Just out of curiosity, this just clamps on to the barrel without any mods to the barrel right? I've been thinking about building a dissipator out of an m4 barrel turned down in front of the gas black, but leaving enough to clamp a front sight to since finding a good lightweight barrel seems impossible(and then I'd need a front sight for a lightweight).

Ah.. I though you had backed away from the idea like I always do when I get tempted.

I'v used them on a couple of different builds, They zero properly with Colt carry handles.

Like buttstock extensions there are two carry handles -- Colt and "Others" (I don't think calling them MILSPEC and commercial are appropriate but hey, what the heck).

The Colt rear sight shelf is .835 inches from top of Picatinny rail (requiring the higher "F" FSB) while the others are .795 -- they don't need the "F" FSB.

The mis-match comes when you use a higher Colt carry handle with a standard FSB -- the front sight flange may be above the top of the shelf on the FSB when zeroed so you'll either need one of the longer front sight blades or swap to an "F" FSB.

and pretty much all aftermarket BUIS are made to the Colt height
