Home Forums Hunting & Shooting AR and Tactical Rifles LaRue barrel sale

You put the "weapon system" i.e., gun scope & ammo into a mechanical rest, fire 30 rounds (fully, compliant, statistically valid sample) & then calculate the standard deviation & perhaps the capability index (CpK).

For example, let's say that the standard deviation (SD) is .5", meaning that the average distance of all shots from the center of the group is .5".

Therefore, 99.7% of all shot fired will be within the circle defined by +/- 3 SD or 3" in this case.

So now that we know the "capability" of the gun (& scope & ammo), we can put it into the hands of the shooter & fire 30 more shots.

If the shooter is as consistent as the machine rest 99.7% of all shots fired will be within a 3" circle determined above; conversely, if the shooter is not as consistent as the machine rest, the group be something larger than the 3" circle.

If so desired, you can now calculate a new SD & capability, as above, for the gun, scope, ammo & the shooter.

When that capability is defined, again, for +/ 3 SD, you can now be statistically sure at the 99.7% level that all shots fired will be within that circle.

For example, with the shooter firing the weapon, the SD is determined to be .75", 99.7% of all shots fired will be in a circle defined by +/- 3 SD or, 4.5" in diameter.

it aint over till its over

I'm confused about who doesn't understand who.

Just got my LaRue MBT Trigger in the mail. Based on first impressions and if they price these right, look out Geissele. They are nice.

I spoke to them today about the weight of the stealth upper, its well made but I think I am looking for something lighter. Asked them about Reardon steel and he said "are you that Jeff guy or that Blue guy from 24 hour campfire".

Tell em I need a 2XL T-shirt for all the air time...

Don't be surprised if he pops in and sends more than that. I got a $250 trigger just for participating in a challenge and wasn't even ranked in the top 25.

Just to be clear I told him I was not blue or Jeff. if I get a hat I will send it to you.

Hey, we are the ones stirring it, shouldn't we get the stuff. LOL.

War is holding out on us now, challenges with free triggers and not letting the rest of us know whats going on....

I bet it's an arfcom thing...

I could really use a discount from LaRue, I hate paying retail. Besides I wound up throwing away 15 or more hats a few years ago. Multicam boonie hats are more my thing now, gotta keep the sun off more than just my bald head.

Yes, it was a challenge on arfcom. It wasn't planned and was a one time deal. Mark LaRue just popped in and gave triggers and hats to everyone that competed in the SPR and service rifle divisions.

And the triggers are awesome.

How do they compare to Geiselle triggers?

arfcom, I guess I can handle not knowing that, LOL, just can't deal with them anymore.

Arfcom has a good, no BS, precision rifle section. That's where I spend 95% of my reading there

They have a geissele feel but less over travel. Small difference but enough to notice when comparing side by side to a SSA-E and SD-E.

I have to go look at this, I left ar15.com due to the drivel usually posted there.

Yeah, there is lots of BS in the big sections but they have a good hometown section and great sub forums.

Nice to know. Figured most anything decent Bill put out, would be adjustable through the range of likes and dislikes, IE overtravel etc..

Well, after going back and forth between the LaRue MBT and Geissele SSA_E, I would say the LaRue is on par with Geissele. The pull weights are slightly different between the two but overtravel ended up feeling about the same. LaRue is claiming his are "better" but I am not really sure in what way. They are nice though.

I have no experience with adjustable Geissele's so can't comment on them. I would assume they are even better, though I couldn't imagine a better feeling trigger than the SSA-E.

Someone one on EBay already has their 199.00 barrel for sale
