AR 10-TBNF & 10-TBN differences

[monkeybiz192]

Can someone please shed some light on the differences between the 10-TBNF and the 10-TBN.  Buds is offering both with differnece in the description and I can't find anything on Armalite's website.

 

Thanks in advance

I believe the TBN is a discontinued 24" model and the TBNF is their new AR-10t 20" model.

Call Buds. A guy from AR10t.com ordered the TBN and they sent him the TBNF instead.

Called armalite, TBNF has the forward assist. TBN apparently is the older model they discontinued.
