Lube. Whatever lube you use - the heat from firing is separating the lube components.

As long as it's not the cheapest of the cheap, and lacquered. That shiit causes it's own problems with the chamber,once you burn that lacquer off the cases. It can gum shiit up quick, and it's hell to get out of the chamber.

That A2 rear sight setup was for major range changes - out to 800 meters on the M16A2 fixed carry handle (incorporated into the upper) and out to 600 meters on the M4 detachable carry handle. The M16A4 detachable carry handle only did 600 meters, because the length of the threading for the 800 drum is too long to use in a detachable handle. That thing goes down into the receiver body a little.

Sad news to hear - lead singer of Soundgarden and Audioslave. Suicide. RIP, Chris - you helped change the entire music scene...

Wait - WHAT?! Your wife is selling nurses that are shooters, and the package deal comes with a Glock.380? The sale lasts for the next two years?!... Did I read that right?!...

There were some seriously butthurt people in that thread, for the first vid - some guy saying he's never, ever buying another Vortex or Hornady product, after this...

That's a damn great looking rifle!

Yep, that's almost universal - it needs to cam over.

Holy shiit! Don't dirt test this one!

You'll need to define your meaning of "tactical functions" a little more. Please be specific.

See?!... He was pushing that dolphin penis out there, and was gonna take it if he had to!

I personally don't know shiit about tuning a .243, but that gas port was WAY too small. 5.56 on a 16" carbine gas barrel is bigger than that!

That's good, because Dolphin Rape is real!

Damn, I like that knife.

I like it, brother. Alot!... All those powders look like good powders for this cartridge. Did you get any of the ES and SD numbers from those loads?

Definitely won't hurt - and very well worth trying. Something else to check when the gas block is off - gas port size in the barrel. Not many X-Caliber barrels have been through here (members here), but I do know of one of them that had a gas port that was too small... Had to be drilled up...

Triggers that light are hard to find. Trying looking into Jard. I know they have one that goes down to 2.0lbs, but I only know that because I've had one for years. Super-short reset, which makes it a pain in the a$s to shoot in a semi. If you don't follow through on the trigger pull, it resets and shoots again (still semi-auto, not failing - just short reset...). Another option is the Geissele Hi-Speed National Match trigger. You won't find anything nicer. Might not get down as low in pullweight as you want, but after you shoot it, you won't care. https://geissele.com/hi-speed-national-match-trigger-set.html

Check what Matt said, above - but I'd still pull the buffer out and measure it. If it's really a .308AR rifle buffer, it should be pretty close to 5.200" long.

^^^ Something funky going on with your sights... Hard to tell from the pic. Looks like: Both mounted backwards, and need flipped around. Kick that front as far forward as you can, and get the back one near the end of the upper receiver when it's folded down.

I don't run any adjustable gas blocks on any of my rifles - so, they'll work without adjustable gas blocks. I think I understood you correctly. Port in gas blocks should be 0.125", across the board - that's the maximum gas port size you'll ever find in a barrel.

Right on, man - that is one solid rifle, right there.

3 of my large frame ARs are running collapsible stocks, and only one had a fixed stock. On the 3 collapsibles, all parts are the same. Armalite AR-10 Carbine receiver extension, Armalite AR-10 Carbine buffer spring (Part # E1095), and an AR15 Carbine H3 buffer. ^^^ Reliable, consistent, and always performs.

Either on the gas system. 16" will almost always have a midlength gas system, and that's a good combination. On 18" barrels, you'll find midlength and rifle length equally, in a barrel search. I've got an 18" miglength gas stainless barrel from Rainier Arms that is an absolute tack driver, and it doesn't kick like a mule or anything like that. It runs well. 16" midlength gas steel barrel from Faxon, and it is wonderful. Not overly loud at all, to the shooter, even with a 2 chamber brake on the end of it. It certainly sucks for anyone beside me, though... There are a couple more barrels in the large frame ARs I have, but those two above are great examples. A 16" barrel will accomplish what you're seeking, as you stated above - 350 hunting, paper range out to 500... An 18" barrel might give you a little more in the fps range, but not much. The 16" is going to be more maneuverable, for sure, and 2" of extra barrel will affect the swing weight of the whole rifle, during hunting.

Very cool.
