Default Change upper?

Has anyone experience changing/swapping the upper on their M&P Sport? What was your experience? What Upper did you choose?

Thanks!

It took 2 seconds. Not much of an experience. Was about the same as changing mags

My Colt upper my friend wanted to try on his M&P.

I bought a new upper with bcg for my M&P. It was a Radical Firearms upper.

18" 416-R Stainless Steel Hand Lapped Match Grade barrel, with Rifle Length gas system.
1/2x28 Thread Pitch, with a 1:8 Twist Rate
Melonite M16 cut, Full Auto Bolt Carrier Group, HPT and MPI.
Ships with Radical Firearms Zero Impulse 3-Port Muzzle Brake
15" free float Radical Firearms M-LOK FCR rail.

It's a nice upper. I'm shooting 1-1.5 MOA with good ammo. I think it is capable of better accuracy but any shortcomings is shooter related.

The nice thing is that I still have my M&P upper with a nice red dot on it. It's zeroed for short distances.

just don't use the old bolt with the new upper - keep the bolt together with the same upper.

only issue for most people is they now see an upper sitting around so must be time for another lower - of course I don't need a reason to buy another upper or lower other than just because I want it

The ability to change uppers is one of best things about AR platforms. Wish I could swap engines so easily!

I did for a while until I put a matching lower on the second upper. And again on the third upper until it found a matching lower.

Yep, additional uppers always seem to turn into additional rifles!

Ain't that the truth. Upper and lowers like mates.

I'd get a second upper if you want to switch calibers to say a .300blk. If you want a more accurate .223/5.56 with better parts, just buy another whole rifle IMO.

AR newbie here-

How easy is it to convert an AR to 9mm? Any suggestions on a cost-efficient way to do so?

Just takes money, and parts, and time...

Radical 300 blk upper shoots awesome with my mp15 lower. Takes less then 10 seconds to swap out. The problem is the addiction to the AR platforms with mods and furniture, it's worse then a crack addict
