I am in need of a virgin F marked front sight base.  I understand that Colt is not manufacturing these, although they may finish machine them.

Is there any sources for one that came from Colt or are there others out there from someone else that would be an acceptable replacement (acceptable meaning, you really can’t tell the difference)?

I see that BCM offers one and also retrorofles.com has ones listed. I have ordered BCM carry handles in the past that were identical to ones that came with Colt rifles, will the FSB be the same?

I am not interested in using a take off and oversized pins at this time.

I order mine from BCM. Have one coming today. Then off to John Thomas at Retro Arms Works for pinning. Plenty of complaints about retro rifles.

JSE is my place for AR parts. Ordered a bunch before, never a issue.

CMMG and BCM have been near identical IME. Usually sharing the same forge markings.

Thanks.  Ordered one of them from BCM, we’ll see what it looks like when it gets here.  Apex one. Would have been good but I don’t think it was F marked.

I bought this one from Numrich. 2 left in stock, F marked. S&W Sport 2.

The "milspec A2 style" descriptor is misleading.  I do not believe that they are standard/A2 height FSBs, but rather F height.

Finding someone at Apex to give an accurate/knowledgeable answer could prove impossible.

Either way, the BCM are GTG as well.
