New M&P 10 will not group

[copemech]

Varget is the powder that saved me from selling the gun. I couldn't get 180s to shoot worth a damn. I'll look when I get home tonight and see look at the load data I have wrote down.

Copemech I recognize your screen name as I feel we have danced the same dance with our M&P 10s. One thing I'd recommend to you is to change the goofy BS flash hider that comes stock. It very well may have been coincidence but after I changed mine I noticed my groups did tighten up.

Yes, I have been around here for a while now. I had a ton of issues at first and have seen all the others.

I got this overpriced toy thinking I could do a bit of longer range shooting. I know what it is and do not have unrealistic expectations. I expect about 1.5 moa out of a standard AR with standard ammo and I would expect something similar here. Right off the bat, it would not cycle properly with Nato spec ammo? Some of those groups looked like a shotgun hit the target!

S&w's answer- Oh, you have to use American hunting loads! BS, the rifle is undergassed. Enlarge your port to .073-.075 from the .068-fixed.

I am on my third muzzle device. With or without made little difference to accuracy for me.

Even expensive ammo like Fed GMM was not great. Maybe 2moa and nothing to write home about. My old 1979 Colt AR will do that with open sights if I have a good day.

This is the first rifle I ever put a 14x scope on so I can see what I am missing!

Here is another option for a .30 cal AR. If you already have an AR15 in 5.56, you can buy JUST a .300 blackout upper and BAM you've got a .30 cal AR. I had the .30 cal itch and bought an upper at a gunshow and am very happy with it. You don't even have to buy different magazines. Cool stuff. No, it's not a .308, but it is punching the same size hole in something. I think I paid around $400 for the upper with all parts so it's ready to install. It takes less than sixty seconds to swap it over.

I can't speak for every DI rifle but generally they are moa capable

The M&P10 does have the reputation of being accurate and being able to hit targets out at 700+ yards. There is even video to prove it has done with a basically stock rifle.

On here, it seems to be hit or miss. People either got a great rifle or did not. Now, I can't say that everyone one who has reported problems on here were not the problem themselves for one reason or another. I don't know their capabilities or lack of capability and it isn't my place to judge that, especially since I was not there to see them shoot or even met anyone on here in person.

I do know the accuracy reputation of AR rifles in general and it is generally around 1.5 MOA, some better, some worse. The basic design is based on a combat weapon system that has the average foot soldier in mind and the expectation of "Minute of Man" at about 300 yards or less with military ball ammunition.

This view is not meant to be disparaging of the forum members, the AR platform itself, nor Smith & Wesson in anyway. Just a comment on the AR in general.

I constantly shoot 1 MOA groups at 100 and 200 yards, and 1/2 MOA on good days. It likes the Federal Sierra Match King 168 and Hornady 168 and 175 match, but I can get MOA with PPU 168, 165, and 175. Even with American Eagle 150. I credit my Geissele trigger, AP Custom carbon fiber free float handguard. I recently switched from a Surefire to a Little ******* brake with great improvement. Picked up the gun I think 18 months ago for $1299, so lots of room for upgrades. The goal is 500-1000 yards. Unless something is wrong, the gun is awesome. GunsAmerica has an article with a stock 10 hitting 1000 yards. Don't blame the gun, unless there is a mechanical issue.

I'm hoping mine will be like yours but with Remington 168 Match since that is what my bolt gun seems to like best. The bolt gun shoots Federal Sierra Match King pretty well but likes Remington better.

I've done similar upgrades like you have, so I'm hoping my experience is as good as yours.

I'm enjoying my basically stock (Wilson TTU trigger & updated Magpul furniture) scoped M&P 10. It definitely likes Sierra 165 BTHP bullets in front of IMR-4064. Shot a 0.625" benched 100 yard 5 shot group a couple days ago. Out of 20 rounds (four 5 round groups) the worst group was 1.250". I freely admit I was having a good day LOL. Ladder loaded some 178 A-Max - groups not as good. Hope this info helps.

Just got my rifle back from S&W , They installed a new barrel but did not inform me of what they found . The groups are much better , no fliers but 1" is the best I've shot most hunting loads will stay within 2" at 100 which will be good for deer and hogs. I also installed a Geissele trigger and was hoping for better results . But I'm still trying quality hunting ammo hoping to find what it likes .

2" with a hunting load is not bad out of an AR. One can always hope for better. I'm hoping for the same when I get a change to run some rounds through mine and see what it does. For one reason or another, I haven't gotten a chance to take it out since I got the upgrades done on mine.

I'm hoping for 3/8" with match loads like my bolt rifle does and with the same rounds my bolt rifle likes (one can dream, right).

Well, good luck on your search and I hope you get at least close to where you want to be.
