RPG ULE Bolt

[slade]

I have to ask, why the venturi? I thought that they were pretty much proven to be useless and a restriction on airflow..

probably the easiest way to make it, considering the valve stem on the bolt. that needs to attach to something, and its probably easier to drill round holes than mill something out, or make it any other way.

Depending on what the bolt is made out of it good be more of a structeral or cost savings issue.

No stone will go unturned. All of you make interesting points.

v1 and v2 look very different from each other. v3 will likely look nothing like v2.

at the end of this it would be pretty cool if you could snap a pic from the v1 through the actuall production bolt.

I agree with personman.

If the face restricts airflow, efficiency may lack and recoil increase, no matter how lite the bolt is.

I agree with personman.

At the same time, the smaller volume leads to less expansion before it gets to the ball.

Id love to agree with you both. However, without that proof, backed up by data, its all speculation. Which is why its being tested.

But if you have a link to that data, Id be very interested to see it. If at minimum just to see how they came to their conclusions.

FYI - There is no direct correlation between a lack of efficiency and recoil. The Matrix which has very little recoil, is less efficient than some of its poppet-valve counterparts.

Recoil is largely attributable to reciprocating mass(ie weight), among a few other things.

More importantly--- This is the 2nd prototype, not the final product. The final product may look differently than what you see here.

Hope this helps.

Don't worry guys. He's testing this to get the most efficiency out of it. He tested a venturi style face and now he'll test something else probably. The venturi does restrict airflow, and therefore it probably won't be the finished version. But whatever the finished version is, it will be what Rogue got the most efficiency out of. So don't worry. He's not going to put out V2 if V3 gets better efficiency. He's still running testing and collecting data. That's the empirical method and that's how this needs to be done.

I don't have any acutal data. But I'm pretty sure that a bolt with larger openings on the face will lead to higher flow.

I never said that bad efficiency would lead to more recoil. What I mean't was you would have to increase the pressure/velocity with the verturi face. This would make the bolt move faster and cause alittle more recoil.

I have faith that you will deliver the best performing you possible and that these are the prototypes. I'm just trying to give you come input from a mag user.

[personman]

warbreak im not really worrying about it, just curious.

I'm sure Rogue's finished product will be amazing, like all of his other products.

Why didnt you use the nose that AGD used for L7 bolts? Is it too hard to manufacture?
Cause it would be a pity if some of the efficiency gained by having the lighter bolt was lost because of the tip..

At this point the only thing I can divulge is its weight. The rest is left to your curiosity

But, as Ive said---no stone is going unturned.

Agh.. not only are you being evil and secretive, your post count is 666...

coincidence? I think not.

tru dat

[slade]

his post count seems to just hover around 666, and hes been here since 2001. that cant be right.

Post counts lately have been wacko. For the past 5 or so months my post count has never exceeded 1,675. I know I have passed that mark.

yeah, i know . i know of one thing at least, there may be more.
