What options are there as far as soft sided AR cases.Who makes a good one. Grizz.

WOW! My wife is going to hate this page, it's going to take me DAYS to read it all....

I don't know where one would look, but some links to the wssm calibers that come from DTech, Olympic, etc., might be a good addition. (As if you haven't spent enough time already!)

Thanks for the info!

I want to build an AR in 6.8 from the ground up where is a good place to order uppers and lowers also looking for a barrel in 11" to 14".

thanks

Thanks But i want to build it. I just want to find a good place to get every thing for a 6.8. I have built 1 in 5.56 just wanting to know where i cant get them.

I posted on one of the " different brands" links but all of it was over a year old so I thought I would ask the ? here. Why does no one mention the Colts? I have a match grade Hbar 16 I bought years ago when they said they were going to quit making them. I allways wanted one so I figured I had bettter get one then. I have been nocking around the idea of swapping the top for a longer one and trying it on the yote hunt? HOOVY

The Colt is, was and will continue to be one of the more expensive as well as desireable of the AR15s. If you wish to trade a very clean, all original Colt Upper for a Bushmaster, RRA, DPMS etc, etc Varmint/Target it will not be hard to do. Unless you have a good trigger in the Colt Lower you might consider swapping the whole gun for the congiguration your wanting with a good trigger. Make sure you know the value of your Colt before swapping.

well I was just thinking of getting a new upper. Galati has some real good prices on uppers and just the barrels. Can't decied which way to go??? One other ? why do the longer barrels have 1/9 twist and stock is 1/12??

THANKS !! James

The slower twists were used on the earlier guns and evolved as the rifles were changed diff types of ammunition, bullet weights etc. I think for the most part at this time the 1 in 9 is most common with a lot of folks useing a 1 in 8 or even a 1 in 7 to stabalize the heavier bullets. If you are wanting Varmint/Target type accuracy you will probably want a chrome moly or stainless steel barrel with a twist appropriate for the bullet weights you intend to use, probably a 1 in 9 unless you intend to shoot 55 gr with a poly tip or heavier which you may want a 1 in 8. BTW you will find the diff twists in all barrel lengths.

THANKS I'll do some homework ! Hoovy
