so im kind of an accuraccy nut, and to be honest i havent even got to do much testing with my ar, but i hope to be doing alot more soon enough, just to damn cold right now! if you guys could do certain things to an ar to make it super accurate what would you do. my m&p currently has a free float on it. it is soon going to get a trigger job, gonna go the cost efficiant way first before i got for a drop in. and i am a hand loader, i havent done any yet for the ar, just my bolts. anything thing you guys like to do besides the obvious to help for greater accuracy? i will say i just signted it in last week, with cheap pmc fmjs, and the horrid trigger these ars have, and it shot 1inch group maybe a bit more, at 100 yards, which i felt given the ammo and trigger, wasnt horrible
making an ar more accurate

If you're going for accuracy, my recommendations are:
Free float the barrel.
Aftermarket 2 stage trigger such as a Timney, Geissele, etc.
A quality optic.
Quality rings.
Good factory ammo, or OCD attentive handloads with good projectiles.
As for handloads, there is a separate thread specific to the M&P 15 rifle in this sub forum.

You can also try polishing your trigger with a stone and polishing paste. I have had real good luck polishing these triggers. Once you get the machining marks polished out the trigger becomes a nice easy pull. After polishing or with polishing you may try a set of aftermarket trigger springs.
I also have the OCD attentive handloads LOL

I agree with what others have said - freefloat, trigger, optics, reloads. I just put a CMC drop-in trigger in mine and MAN - what a difference! 3.5 pounds pull but it feels more like a few ounces and smooth as butter, for less than $180. The next thing would be a better barrel.
i definatly tought about a barrel and new trigger. but want to try the polish job first, my gun has the standard weight factory 17in barrel on it now, i wanna try it first before i go that route as those two are expensive upgradesc. i have a nikon ar scope and rings on it now. so im set for optics

shot sport for a year, ~2500 down range so far.
best i've done is .651moa, 5 shot group at 100 yards, 55 gr sierra, 25.0 varget.
maybe some others will post their results - to see how capable a sport is.

Just my thoughts.
Considering the Melonite coating and the twist that's in the stock barrel made by Thompson. With the groups you are getting now with factory loads it seems a barrel would be a waste of money. I would think trigger and finding a "roll your own" that your girl likes would get you where you want to go. You've already free floated which is my first order of business when mine gets here. Load development until I get parts for the free float. Which will be after the current panic dies down along with prices. She will wear Leupold glass.

How many of those 1" groups at 100yds were 5 shot or 10 shoot groups? If you can shoot 10 5 shot groups or 5 10 shoot groups in a row that are all under 1" you may have a good barrel.
In the accuracy game, you start with an accurate match grade barrel, that was chambered and fit by a gunsmith that is known for building winning competition rifles. Follow that with competition grade sights. Then you can worry about free float, triggers etc.. Also, you have to have the knowledge, tools and components to assemble match grade ammo. It also helps if you have the knowledge and skills for accurate shooting. If it was easy everyone would be doing it, but everyone isn't doing it, so it must not be all that easy.

I myself am shooting groups under 1" almost all the time, the only time I dont, with either of the Sports is when I myself am not doing my part. If I dont start by getting calm and getting control of my breathing my groups open up, still under 2", but when I get myself in the game these barrels are capable of it. They are different than traditional 5.56 barrels. Some people claim that you cannot do it with these rifles. After they have shot them, especially with "roll your own" ammo, if they cannot then it makes me wonder what they are doing. Both of these are extremely good to 300yards after that bullet drop and environmental conditions play a big part. 5R rifling is becoming more and more popular in top tier rifles and after market barrels along with the Melonite or whatever they want to call their treatment process. As machining skills have become more accurate so goes the things made by those machines.

after looking at the target id say the 5 shot groups were a bit bigger then a golf ball, so either way i do feel like they wernt to bad for cheap factory ammo. i wanna change one thing at a time, im gonna probly do the trigger while im working up some handloads and see how much they improve.

You'd be surprised what a little buffing and polishing will do to that trigger group. Cheaper too..

What range are you shooting "golf ball" groups ?
You'll really be surprised when you get your loads dialed in. Not to mention the polished trigger.
