I recently picked up this used 11.5" barrel and was told it was an FN barrel, possibly an FN made PSA Premium barrel.  I've got comms out to PSA but the previous FN made barrels i've seen have the FN logo on them.  I dont see anything on this that definitively makes this an FN barrel.

The barrel is chrome lined.

Thanks.


PSA confirmed my suspicion:

I have never seen a barrel PSA CHF, no CHF, or FN CHF that looks like that. I talked to our barrel purchaser who has been with PSA for over a decade and he agreed with me and said he has never seen it before, and said that he was 100% sure it is not an FN CHF.

Thank you,

Josiah

Confirmed by pics on their webpage.

Nice barrels.

That barrel says 5R. The OP’s says NATO.

Chamber /rifling type /twist rate notation varies.

The "XR MP" notation is unique to Sionics.

The profile in the pic matches Sionics and Green Mountain, which makes a lot, if not all, of Sionics barrels.

If this is indeed a Sionics/GM barrel then it is of premium quality, though I would question the CHF claim unless Sionics has this in their catalog.
Left-handed and right-minded!
