Truly accurate ar15

I had one. It was a 264LBC ( 6.5 Grendel ) with a Wilson barrel. Shooting Alexander Arms ammo Lapua brass with 123 Scenars it always held 1/3 MOA with the factory loaded ammo.......It's just something a bit different but offers great brass and IMO a superior round to the 223.

Rick

alexander arms is no joke. They make some top quality stuff.
 
Dtech 20P upper. Load development with two different powders, N133 and 8208 at many different charge weights. 5x5 (actually 4x5 and 1x7 because I was pressure testing the loads in addition to looking for accuracy loads) shot quickly in succession. None over 0.75" and average of 0.63" (center-to-center) over a labradar, so no qualifiers about "if I do my part." My experience with WOA and Dtech uppers are that sub-MOA accuracy is typical in large part because they use good barrels which is key. I'm sure other vendors do well too, but these are vendors that I have personal experience with. BTW, 8208 gave more speed than N133 when approaching max loads, but both were accurate. Nothing to brag about but nothing to apologize for either.IMG_2988.jpg

Here's one, kind of.
http://forum.accurateshooter.com/threads/ars-arent-accurate.3980830/

Stuck in Alaska at work so no pictures, but, I built a .223 Wylde chambering with most of the same stuff and using:
- Starline Brass
- 24.3gr CFE223
- 69gr Sierra MK
- CCI BR4
Neck turned to 0.003 "grip"
2.260 COAL

I get pretty much the same results.
Another recipe for accuracy through the mag has been:

- Starline brass
- 24.1gr Varget
- 73gr Berger
- CCI BR4
Neck turned to 0.003 "grip"
2.253 COAL

I have found 90% of the accuracy comes from the barrel, choose a good one! I free-float from a Harris bipod when shooting from the bench.
 
I bought a Stag with a heavy varmint barrel. I forget the model....6 ....11... anyway it shoots bugholes with my handloads.;)
All day long except Tuesdays, Thursdays and Fridays, rainy Saturdays and Sundays. It hates Mondays... Wednesdays are good......sometimes....:eek:
 
Hats off to AR Service Rifle Shooters...
600 Prone in my day with Iron Sights and shooting a 197 -200 out of 200 was job well done.
Now a days a scope makes life easier.
I set a Record at Milan Range in Il . 1997 at 600 yards AR Match Rifle Built by me Iron Sights 200-10x .
It stood till 2018 when tide by a Palma Rifle .
I am at this time Building AR Match Rifle # ??? To shoot F/Class to 600 yards just to see it work .
The base of the Rifle is 26” Barrel Gas System moves 2” forward. Chambered for 80.5 Berger’s .

Shooting a Iron Sight AR with a 20” Barrel is not a easy job at 600 on a Paper Target .

Now that's some funny stuff right there
 
Thank you all for your information and for your contributions. I am going to go in and build one for me.

I have a spare barrel blank that is begging for a build. I will post the build and my testing as it happens.

Thank you all very much for cutting through the noise. I rely on members here for a real world take on current "best practices". Thank you all.
 
I had a very accurate AR. Rock River lower and an upper . The upper had a 1" stainless bull barrel, like 24".. My load would shoot at least 3/8" at 100 yards every time from a bench. I sold the upper. It was too heavy for this geezer.. Yes I replaced it, with an Adams arms piston upper.. Doesn't shoot 3/8" but does good enough for the targets I shoot at.
As far as what I saw Rock river were the most accurate out of the box AR's
 
I have an old (1997) Colt "CAR" AR with the original 24" 1:9 twist SS barrel with many, many 1000's of rounds through it. The gun is completely stock except for a Jewell trigger. It consistently shoots .5 moa, 5-shot groups, of 50gr VMAX with 26.0gr of H335 @ 200 yds. I have read rumors that Colt used Krieger barrels on their "CAR" models, but can't find any definitive proof of that.
 
The right combination of upper, trigger, scope and some Berger 80.5 sitting on top of 24 grains of Varget will shoot under .4 MOA out to 800. I have loads that will shoots the 77 SMK out of the mag well under .4 @ 100. I use once fired PMC prepped brass for my long range loads.
My shooter is a complete RRA with a 20" Varmint upper. I use a Nightforce 12X42 BR scope. The trigger is an ELF adjustable. I have the bag rider on both ends and shoot it like a BR rifle. There is absolutely nothing hard about keeping a quality AR running.
I have several uppers just for blinkers.

what length are you seating the 80.5 Bergers ?

Another NRA/CMP service rifle shooter chiming in...

question 1- what is your rifle actually capable of in your hands on a regular day, not the wallet group best day

Shooting in position and with a sling, I'd say that my rifle is capable of around 1.75MOA, on the average. Some days are better and some are worse. Usually I'm shooting 200/300yd reduced matches with the occasional 100 yd match. Off the bench, with my reloads, I can get around .8MOA.

question 2- how and what was used in assembly and reloading of your rifle? ( a guideline if you will)

I assembled my rifle from components with all parts being purchased from multiple sources, whenever they came on sale. Pretty much, it's a mutt of a gun
  • Aero Precision stripped upper & lower
  • Aero parts kit (sans trigger)
  • Geissele Mk7 rail with weights
  • White Oak Armament pre-ban barrel & gas block. Generic A2 flash hider
  • Brownells nitride bolt carrier group. Generic charging handle
  • Geissele NM trigger
  • Magpul UBR Gen1 stock (discontinued Foliage green, so it was cheap)
  • Damage Industries A2 grip (foliage green to match the UBR)
  • Geiselle NM long scope mount
  • Nightforce SR-1 4.5x optic
  • Stealth ballistics stock weight & rear sling mount
  • Ron Brown 1907 Service Rifle Sling

question 3- is it really a useful rifle or is it to fussy to keep going, like a race car more maintenance than driving?

My rifle is not finicky at all. Generally it will get cleaned every few hundred rounds when the bolt gets gummy. The bolt face and chamber get a cleaned in between matches & practice sessions.

I feel that this rifle is accurate enough for the kind of competition that I'm shooting. As long as I can hold the 2MOA 10-ring, I have shot a "clean" target. While shooting X's is nice, I gave up trying to shot ultra-sub MOA group trying chew out the X-ring long ago. A pearl of wisdom that was passed along to me by a HP mentor was "100-0X beats 99-9X any day".

Here's one group shot I recently shot on an MR-31 Target (600 Yard Reduced for 100 Yards) using a Sierra 52gr load. Even with 3600 rounds down the tube, this rifle still holds it's own: 200-9X

Slipping ... nope. You dun fell right there! Must be that Texas hot air blowing around. LOL. Might have to take yer Man-card soon.
 
What I do for this woman. I'm done the humiliation. Now I'm heading to the safe to pull out that Stag and reload for it. Then I'm gonna shoot something!!:mad:

Ooh! Just talked to my cousin! The snakes are out! He saw one! I'm going out to look for Rattlesnakes!! That's "Manly"!!!!!o_O:eek::eek::eek::eek:

so are all of you willing to shoot your ammo from a mag for 600 yards. you knew I was talking about the 600 yards single shot/20 round stage. your friend was crying about me shooting single shot..stay in context.
^^^ Exactly this is why I do not compete in NRA matches. Too many opinions and experts and rules lawyering and "gaming of the system", not enough shooting and sportsmanship. I want to shoot a semi-auto.... semi-automatically!

Lol, gaming? If you want to see gaming, go watch a PRS match.

Highpower’s rules are clearly defined and “gaming” won’t earn you spot on the winner’s podium. It will only earn you ridicule in the clubhouse.
 
"If you want to see gaming, go watch a PRS match."

Or a USPSA match which I shot actively from the early 80's until early 2000. Was a "B" class shooter with an uncompensated .45 shooting major loads. In that discipline most of the gaming was figuring out how to legally shoot a stage within the rules to achieve the highest score, did my share of that and it was generally expected and accepted. Lots of room for personal technique in that discipline. That and the fact it is rather dynamic makes it enjoyable in your ore-arthritis years. At least it was for me.

Not at all sure that I understand how you could "Game" an NRA or CMP sanctioned high power match and I shot a lot of them unless you had an accomplice buddy pulling your target and that would make you very unpopular and most likely told not to return. If XTC and Long range HP is such a farce why does the military put forth so much time and effort to field successful teams? I do have friends that still think across the course has gone to the dogs since you can start in position even though they can no longer do that themselves. They also don't like the introduction of optics on service rifles or in bulls eye shooting even though a large % of in the field service personnel are equipped with optics and none of my complaining friends have ever shot a bulls eye match.
