Re: AR10 Help fronm the PRO:s

once you get the old barrel off, take the new barrel nut and use some Wheel bearing grease, put it on the upper reciever threads and on the threads in the barrel nut, turn it down hand tight and loosen, do this 4 or 5 times, then torque it down. As for the gas tube and gas block or FSB, the pins taper see which side they taper to and drive the smaller side in the bigger hole, usually left to right. And you should be good to go

No Pins the original Armalite Allen screw clamp gas block. I know I will have to maintain the space to make up for the front handguard retainer.
Thanks for the information deadly0311, first attmpt to disassemble a AR upper.
Doing a PPA before starting (potential problem analynasis), someting I learned from DAD.
Any more information, realy looking for a accuaracy enhancing steps to take or things to prevent a FUBAR.

Well I have installed the FF handguard on the AR10, looks just like the "T" model SS barrell and all.
Is a SS barrell from a few years ago.
Now to see how it shoots, will probaly be next weekend to go to the range.
Am ready to try the 175 grain SMK, with R15, any hints?
