Some time back I changed the stock on my M&P10, added an adjustable gas block, and a Troy Rail (this was before the Troy/Dale Monroe controversy--I'd look for a different rail today). I was going to upgrade the trigger but after trying the gun with 145gr ammo (that my M1A likes) and finding low-average MSR levels of accuracy I kind of lost interest.

Last weekend I saw a couple NutNFancy videos raving (positively) about this gun. The interesting thing is they were getting sub-MOA with 168gr ammo but 2-3 MOA with 150gr. (same with 2 sample guns). He was going over all the virtues of the gun and the vices. Funny he names the 3 vices I changed on my own. He also pointed out that the visible portion of the barrel is deceptively thin--it is a fairly heavy profile until the block, thin afterward.

Needless to say I will be playing with heavier bullets and seeing if I can form a second opinion. I definitely agree with Col Whelen that "only accurate rifles are interesting".

Here are the videos:

He does a run and gun video as well.

Mine shoots like his. Nothing to shout about with run of the mill 150s, but outstanding for a non-floated barrel with 168 SMKs.
 
They have good tolerances, being able to do that accuracy and not need an unsupported free floated barrel, or additional weight for the resulting fore end to be durable. While still being durable, reliable, and well made.

I have checked out a number of 308 ARs in the last 5 years and the M&P 10 is a winner. S&W really nailed the important parts on the M&P and still kept it inexpensive and light. You could spend 2-3x the money assembling your own or buying a high end one before you would get a better rifle.


It has well chromed parts where it counts. A pretty good compromise barrel for accuracy and longevity at a good weight using the bullets a shorter 308 barrel is best for, heavy for caliber.
And they didn't waste money on the parts they expect people to switch out anyways like the furniture.
The trigger is not match, but it is also pretty good and safe enough to actually hike around with. While it still breaks clean enough to shoot long distances with.
It really is a good field gun.

Light weight, accurate, and capable of a lot of rapid firepower or a clean take down at quite a distance. You could hunt a moose or defend yourself from a bear.


I think the only way you can really screw it up is to undo the areas it excels like making it heavy by putting it in some of those highly adjustable marksman stocks, putting a big bipod on it, etc
It is an 8 pound rifle, if you are going to make it a bench rifle there is better guns. For a semi auto 308 rifle you can grab and take places it is great. Toss a sling on it and it weighs little more than your typical bolt gun but delivers that accuracy in semi auto with less recoil.


The 168 grains do great. Try the AMAX rounds.
