Looking for some feedback on the pros and cons of each of these ars. I'm interested in the Rock River 24 inch, 1 in 12 but the Bushmaster seems to be a dandy also but a little unsure about the 1 in 9 twist, I shoot 50 to 52 grain bullets. I need some help in making up my mind. Thanks
 
I have 2 RRA's both with 1-8 twist,both shoot very well.They shoot 40's up to 77's with 0 problems.To me a fast twist is more versatile,even with 40 gr.V-Max & Blitz Kings,no fly aparts at all.A slower twist you can only shoot the lighter stuff,but your tube will probably last a few more rounds.
 
I have the Varminter and would buy another over the RR EOP.
The varminter weighs 8.4 lbs. vs 10 lbs for EOP, has a better trigger 2 stage adjustable vs RR NM 2 stage trigger non adjustable. The varminters 1/9 twist barrel will shoot 40 gr. to 69 gr. bullets fine. I use 40 gr V-Max for chucks, pdogs, and ground squirrels and 52 grain Hornady BTHP Match bullets for coyotes.

I shoot nosler 55 grain balistic tips in my Bushmaster and it is sub MOA I have been very pleased with this rifle and often carry it even for small Texas Whitetail deer along with my calling trips.
 
I highly recommend you DO NOT get the EOP. I like my Bushmaster V-Match upper, but I also like and sell many of the RRA varmint models and I hear no complaints. What I am concerned about is the EOP does not give you the scope mounting options you need.

Most scopes mounted on an AR need to have the eye piece be about even with the charging handle. In order to accomplish this, you really need to have your rings further in front of the A4 flat top. Here is an example.

By having that EOP, you will not be able to move the scope further forward. If you do decide to go with the RRA go with their standard A4 Varmint Upper and get a RRA Scout Rail and and decent low rings to go along with it.

I like my set up.

+1 , the EOP's and winter trigger guards are ugly too. /ubbthreads/images/graemlins/confused1.gif
Both are solid companies, can't go wrong with either. I believe the RR comes with a 3/4" accuracy garantee also or used to.
 
I have a Bushmaster Stainless with a 6x18x40 SF Nikon Buckmaster and it is shooting less than one inch 3 shot groups at 200 yard constantly. It will chew pretty much any ammo you you put in it and not jam. Even shoots the cheap stuff (Ultramax) sub MOA but perfers Hornaday 52 Gr to shoot its best.

I also have a RRA 20" Varmint A4 with a 20 inch barrell and Nikon 3x9 BDC. It perform mechanically as well as the Bushmaster. The are groups slightly bigger at 200 yards but still sub MOA. I honestly attribute most of the difference in groups to the optics as I can be more precise aiming with the larger sight picture. One one problem I have with the RRA is that it will make a twanging sound sometimes ( I beleive that the sound is coming from the FF handguard.

Both have two stage trigger and work excellant. For some reason the Bushmaster feel better to me.

You can't go wrong with either in my opinion. Both are quality firearms I would not get the EOP strictly for the fact that if you like the scope close to the receiver you can acheive that with a flatop but you can't lower it on an EOP. You can alway use a riser if you want to raise the scope.
 
A person would be hard pressed to find any 'real' difference between them that you couldn't find between two identical models from the same manufacturer. Both build great ARs and it boils down to price and customer service.

Does RRA help support this site? I know Bushmaster does.

I'm just wanting to know things.

Why do scopes have to be that far ahead??

Mine isn't, it is 1 3/4" behind the charging handle, and I find that it is quite comfortable. Am I doing something wrong?????

Pack Wolf, I'm with you on the charge handle. I have no issues pulling the charge handle on either of my rock rivers. My scope is the same as yours about 1 3/4" behind the handle. I have the EOP 24" bull and the two piece small risers on my RRA lower/DPMS 16" bull upper. The risers on the 16" are shorter than the EOP 24", meaning how close the scope is to the barrel. If it is an issue I think they make an extended charge handle to resolve this.

Big10gauge, I have the EOP 24" bull 1:12 twist and it is a bruit to carry in the field, 13.5lbs loaded 20rd clip and 8x32 Burris signature scope. This is strictly my prairie dog rifle. Extremely accurate. Out shoots my 16" bull DPMS and my buddy's, cousins, and brothers Bushmaster Varminters. I think the weight is where the accuracy is, my opinion. If you want a lighter rock river look at the predator pursuit which is what my buddy went to for his coyote rifle and he is getting the RRA EOP like mine for prairie dogs. The Predator Pursuit has a 20" barrel so you will give up alittle speed but nice to carry for coyote hunting

TenPercent mentions having the scope farther forward because of eye relief and cheek weld positioning. Most accuracy experts in the military recommend snugging your nose up close to the charging handle and even touching it with the tip of your nose. The Army marksmanship team touches their noses to the charging handle and their eye is mere inches from the rear aperature of an A2. If you have a scope postioned behind the charging handle you are likely to get whacked by the scope when using this type of positioning. Also, shooting from the prone position naturally places your cheek position farther forward on the stock and you'll want more eye relief from the scope.

Back to the OP: I would also recommend against the EOP, but would definitely support purchasing a RRA rifle if you can.
 
Those guys must have some pretty long arms.

I tried touching my nose on my charge handle and I can barely reach the trigger with my A2 stock. I do like to get my cheek down tight on the stock. My EOP dosn't allow that since it is so high but I use it to my advantage when I adjust my elevation target turrent up for those 400+ shots on prairie dogs to give me more minutes as the burris dosen't give me much adjustment.
 
I would agree with kelbro on this. I do own the bushy varminter and love it. I don't have any experience with the RRA AR. The Varminter will shoot anything that I put through it an inch or less at 100yrd. With my reloads if I do may part 3/8 groups to 1/2 inch groups all day long. The Bushy is my first AR and I'm very impressed with it.

Good luck
 
I'm not a big fan of the RRA EOP since it's just not as flexible as the flat-tops. Some scopes with over 3 in eye relief are hard to get the eye-relief right without an extended mount. Not everyone is the same size or uses the same shooting style so there are no hard and fast rules.

Here is another option for you to consider. It's the RRA varmint 24in A4 with Larue Tactical SPR 1.5 mount, Larue LT-137 FastFire Mount, and Leupold VX III 6.5-20 X50mm Varmint Hunter. It will put a 20 round magazine into a dime size group at 100 meters. I think that most similar equiped ARs can do the same with the right loads under ideal conditions.

I recommend the BushMaster Predator, 20" barrel, 1:8 twist. I set mine up with a Burris 4-16 posi-lock scope. I load up to a 80 g bullets. I look for up to 600 yds on targets, and 300 yds off hand varmint shooting.

HOLD THE BUS - Dont mean to hijack the thread but TenPercent, is that an Eagle Globe and Anchor that I see on that lower. I MUST KNOW MORE!!!! Where did you get it, who makes it, but most importantly, how can this old devil dog get one! /ubbthreads/images/graemlins/grin.gif
 
I have the RRA Predator Pursuit rifle. It weighs 8.1 lbs 20 inch barrel. It will shoot 5 shots under an inch. I like the trigger and the winter trigger guard is nice here when the temp is well below zero. Trigger pull is great in my opinion. I tried the trigger on a bushmaster at the gun shop and thought it was also good. I went with RRA for price but could have also owned a bushmaster and been very happy. Both are good rifles in my opinion.
