Allright here goes
A few weeks ago I put together a DPMS Oracle from a kit.When it came time to torque the barrel nut, I applied some anti-sieze to the threads and a little to the face that contacts the barrel extension.I tightened and loosened to 30lbs a couple times and looked to see where the extension was in relation to the upper reciever (~.050"?).Now time to torque it and I figure I can get the alignment without being excessively tight...wrong. About the time when the nut failed 80 FtLbs, the gas tube aligned perfect.When I say failure I only mean one of the tabs (tooth?) broke, not the integrity of the nut itself (i don`t think).
So next I have to break out the file to make the four rail hand guard work (slightly bent tooth next to the broke one).
BTW- at this point I hope you`re laughing with me, not at me!
The next thing to go wrong is after about 120rnds the gas block come loose...before I realised this, I tightened down the hand guard thinking it was loose on the stamped plate. Now after tightening the gas block back up the stamped plate and hand guard still have movement slightly.
Probably have close to 200 rnds through this thing now and it does not meet my expectations, accuracy wise.
3.125" 20 rnd group at 100 yrds (about a minute max I think)
Best 5 rnd group is 1.5" at 100 yrds.
What do you all think..( hey! be nice! I know what you wanted to say..lol)seriously though, I think it should do better.
Will excessive torque degrade accuracy this much?
I want to get a free float tube now anyway, `cause I can`t handle that handguard flopping around like Lamars javelin.
Do free float tubes come with the nut when you buy them? do they use a standard wrench? Should I remove the barrel completely from the receiver before installing a new tube? Should I clean all the anti-sieze off and just use some loc-tite at much less torque?
At least the lower went together nicely.
