Question New AR-15 PS Owner.

Bought my very first AR-15. MP AR15PS. Haven't shot it yet, but look forward to it.
A friend sent me a set of flip down iron sights and a low end holographic red/green dot.

Besides learning how to clean it, strip it, and etc, have a couple of questions;

Now before I go shooting with it, anyone have any recommendations of what to run through it, and not to run?

What mags are good/bad/avoid?

Also, just trying to get an idea about mfg date and info. Is there a way to decipher the SN? Mine is SU41XXX

I run only brass cased ammo in my AR's. I avoid others. Some people avoid bi-metal bullets.

I will shoot steel core through mine, but never at steel targets.

I cannot really give any ammo recommendations as I have not bought any in years, other than some M855 when they were going to ban it. I reload all of mine.

I shoot 55 grs mostly.

I like Pmags. I found one AR that would not run them, but it was custom built 3G. It would only lock back on metal mags.

Pmags run fine in all of my ARs.

Have fun with your new firearm!

I have been shooting AR's for a couple decades. Some folks prefer the 55gr .223 ammo others prefer the 62gr 5.56 ammo. My only recommendation is the zero it with the ammo you think you will shoot out off it the most. Reason is the difference in the 2 ammo types will give you a slightly different zero.

Unhappy

Well, contacted S&W about this gun. (I did purchase it from a show)
MFG date = 02/13/2014
Model = 811040
No current recalls or safety notices

From what I'm reading, this is a "lower end" model of the ar15 PS line. CA compliant. Grrrrrr......

I replaced the Bullet Button with a standard mag release button.

Chromed Components: Barrel Bore

Since I'm new to this platform, guess I should have done some research first.

For me, I have a barrel that will last about 12k rounds while the newer versions have about a 21k round life to them.

For me, I would have liked the 811022 or better. Chromed Components: Barrel Bore, Gas Key, Bolt Carrier, Chamber

Now with all that said above and since I don't live in CA, is there anything else I need to change/modify/correct on this particular model?

The triggers on AR's tend to be pretty heavy, one thing I have done to all of my several AR's is the reduced power spring kit from JP, this is a lighter hammer spring and trigger return spring. On rare occasions people have complained of erratic ignition from the lighter hammer spring, I have never had any ignition issues no matter what kind of ammo I use.

There is a broad variety of ammo available for AR's, ranging from the low end like Wolf on up, the only ammo to really avoid is the Hornady Superformance line, it has caused problems in AR's, there's a tacked thread in the Ammo forum about that, its possible Hornady has corrected that issue, I haven't heard of any changes. The most popular bullet weights are 55 to 62 gr and those work well in standard twist rifles like yours.

There isn't any big imperative to avoid the steel case ammo, Lucky Gunner has done an extensive test and the results are very informative.

Shoot the heck out of it. You will figure out what you want.

G56 gave you solid advice on triggers. You could go cheaper and get an ALG Defense trigger. They are the sister company of Geissele.

I doubt you are going to wear that barrel out. Moreover, accuracy tapers off, it just does not stop. The LuckyGunner article shows the cost savings with bimetal projectiles will more than pay for a new barrel.

Run it wet with oil. Look at the wear marks on the BCG. That is wear you lubricate it.

I just wipe my BCG off and re apply lube. Maybe a drop or 2 in the trigger group. I go all shooting season without really cleaning it.

You may want a Magpul B.A.D. lever. I was not a believer in them until I ran them in competitions. They are now on most of my AR's.

OMG - the 3rd party market is overwhelming. Friends are telling me I need X, Y, or Z. And researching out leads down several rabbit wholes. The joys if getting into a new platform.

I plan on shooting it within the next week.
