Lube holes?

Lube holes?

 

The AR bolt carrier has a couple of holes visible with ejection port open, they are there so you can lubricate the carrier/bolt interface without taking the gun apart.

Is it out yet, or did I miss that in the thread??

Oh really? I never knew what those were. I thought maybe it was for the gas to finally vent during recoil.

it's been a busy few days so I haven't had a chance to play with it. Hopefully I;ll have time tomorrow to get the barrel off this one and install the barrel on my project gun. While the upper in question is in the block and in the vise I should have a secure platform in which to pull.

The gases can go anywhere they want, there are a lot of empty spaces and holes around there. The holes may help with that as well I suppose.

You guys are killing me...Where is Pizza Bob when you need him? Like all HP rifles those are gas vents to be utilized in the event of a pierced primer.

 

Now they will get lubrication into the bolt but I doubt that was their design intent.

I have no idea. ARMY says put lube in them.

Huh ... I don't have a bolt in my hand, but I'd think pierced primer gases wouldn't even get to them. I'm failing to understand how they would get from point A to point B. I can see how they can act as vent holes during normal function, but not during a pierced primer, but hey I can be wrong In either case, they are very popular for lubrication.

 

Edited to add: Ok I took a carrier apart I can definitely see how the gases get out during normal operation, but I'm not seeing the pierced primer math.

Hey Ron you could always bring it up here if you need to and we can put some heat on it should it become necessary.
