| I have seen some with a barrel nut and some with a barrel nut and lock nut/jam nut. Do the free floaters have to have a jam nut? Will the handguard try to spin off without one? Also Oly arms makes a free floater for a carbine...Will these fit other ARs or are the brand specific? Also if I were to buy an aluminum free floater....can I easily drill a hole and install a sling swivel or picatinny rail? |
| The Olympic tube should fit any upper that is in spec. and there are many different types of FF rails out there that use diferent mounting meathods, 1 peice that is all in one peice, 2 peice that locks your barrel down then the HG screws on that, 3 peice 1 locks your barrel down a locking nut and then your HG and then you have a few more that I have not used but are 3 peices or more. none should spin off if properly installed your gas tube would also prevent that somewhat. |

I have a YankeeHill, but customized it to butt up against the upper without the jamb nut. Giving it a top monorail. I just ran the barrel nut into the tube, then ran it out 1 turn, then marked it and milled it off there. Theorecially it could rotate off, but the last half turn is pretty hard. Not a hi quality pic but you can see it.  |
