View Full Version : Looking for an FSB for a pencil barrel
Does anyone make an F marked FSB for a 0.625" barrel?
If not, can I just run an FSB off an A2 lightweight and replace the sight post with a taller one?

there are f height .625" fsbs but I think they are very hard to come by. If you want a .625" barrel with a fixed FSB and a flattop other than a colt you're probably going to have to go with the taller post. Bushmaster sells one.

I bought two .625 "F" FSBs from CMMG a few months back, at they time they said they had plenty. They were about $30.

Great, thanks for the info.
I wonder where Daniel Defense will be getting the ones that they are supplying on their lightweight barrels:

I wouldn't think they had A2 owners in mind when they designed these but then again this is my first lightweight build so I don't know much about these parts.

Probably the same supplier CMMG uses, but I'd assume they did the parking and QC in-house.
The CMMG on my wife's is great, though the pinning needed a touch more work after I bought that upper (assembly issues from when their backorder wait was 8mo)

I can't seem to find anything on CMMG's website, their website is strange.
I'm going to call them on Monday, thanks again for the info.

Yeah, it's not on the website. I dealt with Angie via email.
