The CA version of the M&P10 obviously has a BB - which means the ambi mag release that is on the non-neutered version has been shaved...

I'd like to consider going featureless (or at least have the option)... does anyone know where to source a standard M&P10 mag release?

Or does any after-market make an abmi mag release like Troy has for AR15?

I tried to look for something but nothing comes up online. However, I'm not sure what you mean by "shaved" when referring to the ambi mag release. You should be able to simply remove the ambi lever and add a bullet button. I don't think you have to permanently modify your rifle and when you move out of CA you can reassemble your rightful property. Am I wrong in this assumption, or are you just looking for another route?

Good luck, Ryan

The rifle it too new.had not seen one close up yet to figure if it uses regular ar -15 mag release or special release.

I too have one,I called the S&W assy and parts dept at the factory the part # is #43121 $124 however they said they can't sell the item to residents in CA. I said BS they then said no parts available yet. They also informed me the only place you will find a complete schematic is on Brownells website because their S&W lawyers won't allow them to post schematic's. I have noticed that there appears to be 2 styles of magazine catches based on how the lower is made. In searching the Knight Armament (KAC) has one that may fit.Also there are several AMBI Mag Catch Mfg's. I just need to disassemble the mag catch before ordering. NOTE I would suggest having a New BB on hand in the event the factory used RED Locktite on the factory installed BB, so that while you wait for parts you can still use your gun. jmo

the normal M&P10 has all ambidextrous controls (including mag release)... the CA version uses a BB and cuts off the left side mag release paddle (so it can not be used)...

that's what I meant be shaved... sorry, I didn't know how else to quickly describe it in first post :o

Perfect! This is exactly the info I was looking for - thank you.

I may try to find that part number and ship it out of state... I use a Troy ambi mag release on AR15, but I don't think that will work with 308 mags? I'll look into the KAC one.

Mine is in jail right now - so I'll know better when I can take it apart... and yes, S&W really does try to permanently install the BB (I have a couple extra laying around).

Thank you for the responses - I think I have something to work with now... I appreciate you guys :)

friggen awesome! Thanks!

I do have a Free float tube (15" Apex Gator Grip) and YHM low profile gas block... AFAIK it will be direct fit on the M&P10 barrel but (which from what I understand is a DPMS type)...

I may get a different muzzle brake later

On the mags, am I understating your post as S&W has part numbers for 10 round and 10/20 PMags?... I know the 10 round aren't released yet and didn't realize S&W offered 10/20... I might be misunderstanding the mag reference though.

Thanks for the great info!

Also, did you order online or by phone?

S&W has SS 10 rounds in stock so I grabbed 6 until the pmag's arrive if they arrive. Also if you are going to hunt you will need a 5 round magazine, they frown on large cap during a hunt not fair to the critter

mine is still in jail... got it on GB - the going rate seems to be 1450-1600 lately... but keep an eye out, you can grab one for as low as 1340 shipped ;)

blast from the past but the appropriate thread for anyone else needing to uncalifonicate an m&p10..

I ordered the parts listed above straight from smith & wesson, no issue..

https://dl.dropbox.com/s/1idzbh4skhhtqou/IMG_20210428_58108.jpg?dl=0

ordered an unbutton tool but ended up wrecking the mag catch :rolleyes:

oh well, have those in my parts kit in the tool box ;)

https://dl.dropbox.com/s/jy4eljhci3bvl3g/img_20210725_34695%20%281%29.jpg?dl=0

after removing the broken mag catch, idiot button, and bobbed ambi mag release, it was easy peasy..

the ambi mag release drops right in, spun the new mag catch down on a new button and spring - voila!

my S&W invoice info
431210000 LEVER, AMBI MAG CATCH M&P10
400530000 BUTTON, MAGAZINE CATCH
400540000 SPRING, MAGAZINE CATCH

same three parts at numrich, and lots of others in case there's more needed to fully unconvert..

https://www.gunpartscorp.com/products/688250A

both of these rifles are about 7 years old unfired, mostly because of california nonsense..

now moved to the United States, they can live free as intended..

ordered a bunch of proper mags for the m&p10 and the ak47 and a couple thousand rounds for each :p

norma tactical 147gr .308 ran flawlessly in the smith, good buy at .70/rd

and naturally the ak ate up the wolf like candy..
