Are FSB "married" to barrels?

[Keesh]

I would guess they use the same jig.

I've swapped LMT FSBs before with no issue.

Well the idea of a jig makes me want to take a chance.

Now I just need to find a 16" DD CHF LW mid barrel with the FSB. I will report back after I give it all a try.

I doubt it. We still can't get manufacturers to stop making silly commercial lower receiver extensions or do simple thigns like stake castle nuts and bolt carrier key screws.

I've always wondered why this is the case- is it really that hard to come up with some set dimensions for this and standardize?

Even if the military doesn't do it, you'd think the manufacturers could get together and come up with a spec for this- Kind of like how SAAMI works, except barrels/FSBs instead of ammo.

Sure would make life easier...

There's always going to be someone who doesn't know and/or doesn't care about specs.

Still- if BCM, LMT, Daniel Defense, and other good companies all said "Hey, let's pin our FSBs based on this spec." it would be a great advertising point for those who do FSB modifications.

If I recall, ADCO offers a service to replace pinned FSBs. Contact them for more information

Possibly, but not likely the holes will line up.

Considering it's from the same manufacturer, they very well may use a jig to drill the holes, so they may line up fine.

Yeah I thought my brother was full of shit when he told me my holes wouldn't line up. He was right.

I would call up DD and talk to them. Ask them if they use a Jig type setup for all their FSB's. If they do (all manufactures likely do, just different jigs) you have a good chance of it matching. Before you do anything call DD and ask. They may be able to help you out.

Also for those if you looking to or considering shaving the FSB down, you may want to think otherwise. It works yes, but brings problems of it's own such as this one above. If you change you mind, well...
