If I happen to own a M&P Sport .22lr, can I just pop a 5.56 upper on it and call it a day?

if the lower receiver has a buffer tube and an AR buffer and spring and if the mag well can accept stanag mags then sure
No need, they are both .22 diameter bullets, both rounds should be interchangeable.
>>34123205
nope. pins are in a different spot to stop just that. And other crucial dimensions are different as well.
Just get the cmmg conversion kit. works great.
>>34123205
dont listen to this guy op >>34123273
>>34123205
a 15-22? No the upper/lower is not interchangeable at all with a AR-15.
>>34123291
Why would they do that?
>>34123273
This.
.223 will also work.

SHUT UP M&P JEW!! You just don't want people finding out so they buy both. It's 5.56 and .223 all over again. Fucking corporatism!
>>34123356
it's not designed for 5.56. It's designed to be a cheap 22 blowback with lipstick (which it does well). The plastics/fcg/etc just wouldn't hold up
so liability etc etc. Not due to a law per say.

Why are you lying?
Why don't you get a ruger 10/22 like any normal person would with a desire for a 22 lr rifle?
>>34123401
?
>>34123205
also, the buffer tube is fake so even if the pins lined up it wouldn't cycle. bolt would just smash into the rear

You fuck right off, some men have taste and would like a Henry lever action .22

>Not getting a used toz .22 for pennies.
Stay financially cucked.
