I have two free float handguards both OD green and made by AT3 tactical. One is a Spear 12" M-Lock and the other is a 12.5" Quad rail style. They were both mounted but never used. They include the barrel nut, barrel nut wrench, and all mounting hardware. You can see them at this link

The barrel nut does not require timing and installed easily. Asking $75 shipped for each one or would sell both for $130 shipped USPS priority. Can take check, USPS money order, or the old PP friends and family.
Send a PM if interested.
