matteekay Posted December 27, 2018 Share Posted December 27, 2018 I could use some barrel nut help from the AR gurus. This is technically a PCC (Freedom Ordnance FX-9) but supposedly it can use standard AR handguards. I was taking the factory one off and found this setup: Left-to-right, it's the M-Lok handguard, an inner sleeve that the guard mounts to, and I guess that slotted section is the barrel nut? The handguard screws go through the nut's slots and into the inner sleeve, which locks the guard in place (it's also keyed to the receiver). Has anyone seen a nut like that? I can't get it to budge. I can't use the barrel nut end of my armorer's tool as it doesn't have the recesses for the tool's pegs. Link to comment Share on other sites More sharing options...
DesertTortoise Posted December 27, 2018 Share Posted December 27, 2018 Maybe the castle nut wrench fits in the slot ? Or some proprietary tool Link to comment Share on other sites More sharing options...
matteekay Posted December 27, 2018 Author Share Posted December 27, 2018 I did try that. It might be proprietary - I'm going to try dropping them a line. Sucker will NOT move. Link to comment Share on other sites More sharing options...
TonytheTiger Posted December 27, 2018 Share Posted December 27, 2018 Thats a UTG handguard, when you buy one they send a weird wrench with it. I don't think anything on an armorers wrench will interface properly. Link to comment Share on other sites More sharing options...

matteekay Posted December 27, 2018 Author Share Posted December 27, 2018 Oh man, that's a HUGE help. Thanks! That particular wrench looks like it's tough to come by, but their bigger armorer's tool has those slots built in so I might just grab one.
