Home Forums Hunting & Shooting AR and Tactical Rifles List your ar15 accurizing tips

Good advice. Thanks for adding to the thread. Welcome to the fire too..

Well number one improvement for me was adding a good trigger. Mb

Learning a lot reading this thread as I'm pretty new to the AR thing... looking at building an AR one of these days for casual range (probably no competition at the moment) use and coyotes and accuracy is pretty important to me on any rifle I own. Seems like the dogs in our area like to hang up way out there sometimes and a long shot becomes necessary so I'm all about an accurate rifle. The close in dogs sometimes come by like a drive by gangster and catch you by surprise and a quick follow up shot is the one thing the AR platform gives me.

Also, I have this thing about wanting to do an 80% lower just for the project, but won't if it will hamper my search for accuracy.

So, a couple questions to start with- since parts are seemingly impossible to find any more where are you guys finding your parts and pieces? Lowers, BCGs, uppers, barrels, all seem to be in extremely short supply at the moment everywhere so shopping and trying to glean info has been interesting, to say the least.
In all this reading I had a question that I'm curious about- does the chamber you specify with your barrel make a huge difference? What is the best chamber to order- .223, 5.56, or Wylde? I was also thinking a 18 or 20" barrel for this rig, but I'm wondering if that is really necessary for my uses and might add more front end weight than I'm looking for.

Point me in the right direction so I don't spend my kids' inheritance and don't end up with a bunch of useless parts that shoot like a shotgun....

I Wouldn't Fhuqking Linger RINK

Hint.................

Another question- does a kit like the one linked have to ship to an FFL?

Nope.

Only the lower is Registered and the kit ships with EVERYTHING,except the stripped lower,so it's like ordering a fishing reel.

80% away.

Hint.................(grin)

No, only thing that has to ship to a FFL is the stripped lower that is not included in that kit.

A no-brainer....................especially in the current climate. It'll do it all & then some.

Br sure to check GB alignment & tightness, just sayin'.

Agreed. Darn good rifles. Never had a problem. I’ve got two and they’ve both been hammers.

TAG….till I can get back and read the rest. Good stuff for a new-to-AR guy.

None of mine are as accurate as some posted, because I no longer have the abilities some here do.

My tips

Aero M4E1 matched receiver set
Armory Dynamics Stainless Spring Loaded Receiver Tension Screw
H3 or heavier buffer, heavier comes from Slash at Heavy Buffers
Springco Red spring to start, work my way down and order the heaviest spring that allows for function and correct ejection timing
Faxon Lightweight or Toolcraft Nickel Boron BCG
Aero 15" S-One or R-One Handguard
Premium barrel with fast twists
VG6 Epsilon Muzzle Brake
Longest gas system available for barrel being used
CMC 2.5lb 3Gun trigger

The Aero lower has a tension screw, I replace it with the Armory Dynamics Stainless Spring Loaded Receiver Tension Screw, clean degrease, bed the barrel to the action with Loctite 620, then torque to 35ft lbs, once that has cured I will final torque to 50ft lbs. I seal the gas block with Loctite 620, I don't use a suppressor, so I use Loctite 635 to mount the Muzzle Brake

Headspace is often overlooked. MSTN, know for producing some top quality AR's, matches the bolt to the extension, to achieve proper headspace.

Buy a good one to start with, got two Rock Rivers that will do 1/2” groups with 62 grain Barnes

Good advice there. I also like buying good barrels that come with matching bolts. Always check headspace. If I have a good shooting AR with matched bolt and I upgrade the BCG, I'll usually keep the bolt and put that in the new carrier.

Good advice about buying from well known sources with a good reputation for accuracy. I'm not suggesting RRA, as I have sone buddies that have them and none of them shoot as well as I think they should. Keeping in mind, this is 10 shot groups, not 3 shot groups. Funny things happen when you have a rifle that is out of tolerance by just a little bit. Like TWR mentioned: stacking tolerances can lead to problems, especially when firing more shots per group downrange.

A funny story I need to bring up: I bought a good upper from a buddy last year and it was shooting great. I believe I started a thread on it because I was so impressed with the accuracy I was getting out of it:




That sob was shooting lights out when I got it, but I didn't want the A2 front sight on it and wanted to just have that barrel on one of my rifles. I stripped everything, and when I pulled the bird cage off, I noticed about 1/8" of carbon build up on the muzzle. Well, my OCD would not allow that!!! I removed the carbon and after that, it has not shot the same since!!!

I should have left that damn thing alone because it was a tack driving sob. My friend puts together great AR's. He's a retired Airborne Ranger, so he has all the time in the world to work on guns. Anyway, after putting the barrel on one of my ar's, this is how it looked:

Now it has a freefloated handguard and nice clean crown and it does not shoot as well as it did in the non freefloated magpul handguard and the A2 front sight out front. It still shoots well, but not sub 1" at 400 yards:



Just sharing an experience of how I somehow went backwards, and I'm thinking it's my knucklehead move removing the 30 years worth of carbon buildup on the crown and how accuracy degraded. I may be wrong?

Old timer's down here had a saying: "Don't fix what ain't broken."

I'd have cleaned it off too, though.

Spin the birdcage off and put a thread protector on it and see how it shoots.

Not the vastly experienced AR guy here but I have made a couple shoot. Only owned probably 30 different AR's. There is a lot to who is doing the shooting. I like A2 stocks,Geisselle and RRA 2 stage triggers. I have noticed that ammo tuned for the individual rifle means a lot. I like to size my cases as close in headspace as possible with reliability, .001-.002 at most. If a barrel doesn't shoot like you want get a different barrel! I like the Accuwedge because it makes the rifle feel more solid, not sure if it improves accuracy though. This said I have been lucky at getting accurate AR's in different calibers for sure.

I don’t have as much experience as a lot here with ARs, but I’ve saw some really cheap builds shoot amazing.

FF tube, good barrel, good optic/mounts, good barrel and trigger should get you there.

I’ve seen the cheapest Anderson rifles, with a new quality barrel and trigger put out some killer accuracy.
