Looking at my first AR , been looking at RockRivers varmint platforms. Can't decide between 20" or 24" heavy barrel. Gun will be used for plinking and varminting and maybe medium range targets. Would also like to shoot heavier bullets in it maybe 69 - 80 grains. Any suggestions?

I bought a DPMS 24" heavy barrel upper and ended up reselling it before I ever shot it. It was horribly muzzle heavy and unbalanced and extremely heavy. I would think that the 20" would be much better balanced and a more reasonable weight without losing too much velocity.

I was advised by my local AR15 dealer and gunsmith who specializes in AR's to stay away from the 24" heavy barrels as they tend to crack uppers. Again, no first hand experience but a lot of respect for the source.
I bought the RR varmint EOP in a 20" heavy barrel and couldn't be happier. It shoots 69 grain SMKs at 1/2 moa all day long. The 69s are pure murder on coyotes as well.

Thanks to all... kinda excited about the new rifle. Just need to decide on the upper. How long can a person load these heavier bullets and still keep them in the magazine and what speeds are you guys getting with the heavier bullets?

I have a DPMS 20 '' heavy fluted barrel that shoots very well also.
Usually I can get 10 shots into a quarter ( 25 cents) at 100 yards.
Sometimes I can get 10 shots into a dime. Same distance.
As you might guess, I'm very happy with this rifle.
I bought the upper from an auction at GB. The lower came through a FFL friend of mine. Then I purchased (and installed) the trigger from the gun show.
Thought I would mention this because I saved a lot of money this way.
Might want to price it both ways. 'Building' the rifle was not hard to do.
Just my 2 cents.

Book max is 2.260 OAL. I try to keep them at 2.255. Amazingly, these good ARs just don't seem to care much!

Agreeing with Sendero,
My AR's don't seem to care about COL. All of my 50 to 60 g. SGK loads are as short as 2.225 to max mag length. My 77 g. loads are loaded long and just touching lands for single shot feeding. All shoot very well at 200 to 300 yards.
I just wish my 600 yard shooting was better.

First, I ahd not even read your "For Sale Post." My comment was in no way directed at your rifle, it was answering an inquiry in THIS POST.
If you read my post, I stated that I had no first hand experience but that it was from a trusted source. I DID NOT post that comment on your classified ad. Are you saying that posting ANY information for which you do not have first hand experience is wrong, for example loading manuals,other internet sites, Exbal, Quickload, etc? I did not attack the rifle you had for sale, I simply passed on information from a very viable source, to a question on THIS THREAD.
You are the one out of line here.

In fact, looking back, I answered a question on your classified post about cartridge OAL in that particular gun based on my experience with my gun in the 20" barrel version. I honestly didn't even remember that being your post. If I my intention was to bash the gun or screw up your sale, I could have done it then and there.
Again, your out of line.
