I know, I sound as excited as an Ol Maid on her first date, but I am very pleased with the Sport 2.
My first post here was about it not "charging" after about 3 or 4 rounds. Thanks to input here, I was able to solve that problem. Think it was more of a "lube" problem than anything else.
Ran another 120 rds. thru it today, without the first "huccup".
Went to the local Academy...and got some cheap ammo I've never heard of. Monarch .223. Then I added some Winchester 5.56 and TulAmmo into the mix. Along with some other brands.
It ate everything I put in it...using the Magpul Gen 2 mags I bought. ($8.50 each)
Shots were limited to 50-75 yards, due to trees...and my 60 year old eyes. Accuracy was spot on!
If I need to go farther, say 100 to 200 yds...the 7.62 CETME will suffice. But, I know it better than this new rifle. I'm sure the M&P 15 would do the same...just seems a little light. After using the 15, my CETME feels...heavy.
Took my "rattle trap" AK 63 along. Same old same old...works, hits where pointed, eats ANY ammo, although the under folder stock is a b*tch at the range. "Urban Warfare"...yep.
For under 5 Ben Franklins the M&P15 is a "no brainer"...
Gotta' figure out a way to "sneak another one in...

It is a great rifle. Glad to hear you like it, I know I really enjoy mine.

My 61 year old eyes managed 5" groups at 140 yards or so shooting standing up with no rest using my Sport. That sort of accuracy from an entry level AR is really surprising but it's there. My other, more expensive, AR won't do it.

Im 65 and my eyes and my Sport are still working good. Most shooting is from 100yds and Im getting great accuracy. I get MOA or better when Im doing my part.
Glad to hear your new rifle is doing you right.

Been loving my sport ii. I did change the forend grip to a Magpul, and added a Vortex SPARC II red dot.

I am really happy for you! These rifles are amazing and they shoot better than almost all in the industry or at very least they shoot on par.

I would like to offer you unsolicited advice.
I would like to encourage you, at least for the first 1000 round or so to stay with 5.56 NATO M193 or XM193. AE or Federal ts cheap, clean mil/milspec ammo.

I have no quantitative proof just some experience. During the break in (read scuffing of new parts etc. using near as mill spec ammo will help break her real good. It will reduce the cleaning needed and the parts will have a few rounds to cycle under proper loads.

In the Bureau and other agencies they do this prior to ever sending them out to the field.

Look at like breaking in a new engine. Use the best fuel possible. The proper charge of gas through the tube will push those parts the way it was designed.

Its not a must and I WILL not condemn for not doing it its simply unsolicited advice.

Again congrats on your rifle. They are awesome

I agree. Use quality ammunition at first (which may include your own reloads with good quality powder).

My experience with the Magpul magazines is that they are very reliable, but I would suggest that you not leave them loaded for extended periods of time. This is because all polymers are subject to a phenomenon known as "creep" which is a dimensional change in the material when subjected to a continuous pressure (like a compressed spring). If you want to keep magazines loaded and "ready to go" use metal, preferably steel, magazines.

Interesting POV.
When I used to race/build engines, I would break them in with ANY on sale straight 30 wt. oil. It wasn't with the highest priced oil I could find. In fact, my dads 83 GMC 350 SBC I rebuilt is approaching 250K miles. No smoking, no oil burning. One of over 30 I have built/rebuilt.
I own a Sport I and an AR-556. From the very get go I have been shooting steel case ammo, with NO PROBLEMS at all. In fact, about 95% of the ammo I shoot is SCA.
Just sayin'..........

I totally respect that. No qualms. I dont know if it helps at all. Its just something ive done.

Funny fact, when the weapons come back from the Bureau armory they smell like transmission fluid LOL

I know how you feel. I was just as pleased after my 1st outing with my Sport 1. Enjoy and best of luck with it.

I would shoot Tula if it would run. But it short cycles most of the time so I don't. But again, I'm shooting the thing at best at a 3" steel spinner from nothing over 140yds if I'm at the edge of my property, in the woods, and leaning off of a tree to get that far away.

Last couple batches I've bought were Independance 5.56 because I could get either 500 or 1000 of them cheaper than I could find American Eagle at the time. But to me, if the gun will cycle it reliably and you can hit to your satisfaction, then why not. Best quality (supposedly) ammo I've ever shot from any of my AR-15's is some Winchester 50gr varmint hollowpoint my father in law sent me in 2013 when ammo was scarce. It was a 40rd box and I still have half of it left. It just stays loaded in a 10rd mag in case an armadillo or something is in the yard. Best grouping ammo I've actually tried to shoot a group with (and granted, all I buy normally is bulk) was Federal 50gr hollow point, and that was from a 1:7 twist Sig M400.

But I really like my Sport II. If I was more serious about it, I'd probably find some downsides, but I paid $520 for the thing all in at the first of the year, and I don't have a bad thing to say about it.

I've wheeled-&-dealed my way through several Sport 1's and 2's, and evey one has been a fantastic rifle. Given my experiences, and their years of stellar reports from all over, I think the verdict is in: these things are simply outstanding bangs-for-the-buck !
