What upper to get?

[Asha'man]

Options:

RRA CAR-A4 complete upper from Eagle, $449, chrome-lined, 1/9 twist. Consistently out of stock. Can also get from AR15sales.com for $434, dunno if they're in stock or not.

Eagle Firearms complete upper, $469, chrome-lined, 1/7 twist, Shaw M4-profile barrel, RRA upper receiver.

Has anyone used one of Eagle's uppers on anything? Would it be a good mate to my RRA lower? I kinda like the idea of the light-under-the-handguards M4 barrel even though I prefer the look of the CAR barrel. And what's the diff in the 1/9 and 1/7 twist? What's better for what application?

Twist is related to a few thngs, but it's a stabilization issue related to the bullet grain. My next upper will be 1:9 because I generally use 62+ gr. rounds. 1:7 is cool for the 55gr. Google twist rates for AR15 barrels

Check out the legal firearms transfers guy (Pete I think) on EE at ARFCOM. I just spoke with him yesterday and he's got so really solid deals on RRA. Just don't know if the shipping offsets the price savings.

Have you tried calling or emailing Eagle? They might not have the website updated.

Yes.

It's gonna be a pretty much all-around rifle, mostly for plinking with some defensive capability and the odd casual hunting application.

BadShot - AR15sales.com is that Pete/Legal Transfers guy. I got my LPK and buttstock from him back in the spring and it was a pretty smooth deal, so his prices are looking pretty good to me. Plus I'd like to keep the rifle all RRA if possible.

1:9 twist is what you want or even 1:12... as far as brand I will keep my mouth shut just understand you get what you pay for. [wink]

ummmmm......Badshot you kind of got it backwards the faster twist is for the heavier ammo that is why the military uses 1:7 twist because they use 62grn ball.

The ideal twist for 55 grn would be 1:12-1:14 but since you want an all around gun I would go with 1:9. That twist will serve you well no matter what you put through it. That is the best all around twist now get that gun built and come to a shoot. [postal]

Thanks Hunter, I'm still trying to figure this evil twist rate voodoo out.

[The1andOnlyKC]

Get the 1/9, that should serve you well.

Our very own Jensen arms has better prices than AR15sales on complete RRA rifles.
Buy there and you save shipping, transfer fee but you do pay sales tax.
They may have competitive prices on uppers as well.

I'd say stick with an RRA factory upper, better chance you won't have malf's.

And, Hunter - I'd like to hear your brand preference just for grins.

If you are willing to consider breaking up the RRA theme, there are plenty more options.
