Anyone build a A2 style MLOK “other” build? I’ve been thinking about buying palmetto A2 MLOK 10.5 upper and adding the vertical grip. Pin/weld the muzzle . Thanks in advance.

Possible to make this an Other with this kit if you pin/weld the muzzle?  Thoughts?

How long is your muzzle device? I think your barrel OAL needs to be min 12” to be able to make the minimum OAL of 26”. 

[ESB 247]

So as long as the muzzle device would normally be 1.5" past the barrel?   Its a A2 Flash Hider which it looks like it is 1.75".  Although I suppose I could buy whatever I needed.  How hard is it to get it pin/weld?

It’s not a big deal to get a muzzle device pinned and welded. There are a few vendors on this board that will do this for you. 
 

The problem, in your case, is to make sure the OAL of the firearm, from the end of the barrel, to the end of the receiver extension (the brace does NOT count) is at least 26”. You may have to permanently attach a muzzle device to attain that length. 
 

I was to the understanding that an A2 flash suppressor is not long enough on a 10.5” barrel, but I might be wrong. It’s happened once or twice before. 

[ESB 247]

I assumed I would need to weld the muzzle device.  I'd be OK buying a longer one if needed. 

How would I find out the length of the buffer tube in this kit?  PSA Gen4 10.5" 9mm 1/10 Nitride 9" Lightweight M-lok Railed MOE EPT SBA3 Pistol Kit | Palmetto State Armory

Looks like it’s a standard carbine receiver extension.

Muzzle device would need to add over 1.6".  The M2 is 1.75" but it looks like it would not add 1.75" to OAL since it has to be threaded on? 

Correct.

So its milspec so my OAL would be 24.9" according to the diagram on first post.  Muzzle device would need to add over 1.6".  The M2 is 1.75" but it looks like it would not add 1.75" to OAL since it has to be threaded on?  Recommendations on a muzzle device that would work with a 10.5" barrel?

BTW, thanks for the help and quick responses.  

Get the kaw valley linear comp 3.25 or 4.25 version and you’ll be good to go. But It’s going to look weird with that rail. I would look for a different kit. I’ll try and find one for you

You’ll need lower parts and SBA 3 but you won’t have to worry about overall length since the muzzle on that one is 3.25.

Will the Vltor A5 Pistol Buffer tube make it long enough on a 11.5" barrel to not pin/weld the muzzle device?  Would you recommend that one or the carbine one for 5.56/.223?  What's the difference between the pistol A5 AR buffer tube and carbine A5 AR buffer tube?

Good to go. I have the same setup on mine

Yes, it'll make it past the 26" OAL with an A5.  A5 Pistol tube does not have the channel underneath that most braces use - it's a smooth tube.  If you're going to be using an adjustable brace (like the SB Tactical SBA3) get the 7 position receiver extension.

What brand barrel? I used an A5 with a Ballistic Advantage Hanson 11.3". I emailed them and asked if anyone has an A5 setup with that barrel length looking for a buffer weight recommendation to address gas issues. They said use a standard carbine extension tube.

11.5" BA. Modern series I think.

Foxtrot Mike makes a solid 9mm platform, too.

It took some tinkering to get mine running. The trigger and hammer pin holes wouldn't line up with the Hiperfire ECLipse trigger I had purchased for my 9mm other build. 

[RUTGERS95 890]

I'm looking at these to maybe put an 'other' together.  The lower with the brace seems pretty even fair but now to find the right upper

Welcome to the world of non standardized 9mm AR platform. It sucks for sure... 

There are a lot of ar15 triggers that are flat out incompatible with the 9mm platform in general. 

I purchased their complete lower and its run flawless.

You all missed out if you didn't order when I did. After national news headlines they apparently pulled it or discontinued it. It was supposed to be a 10-12 week preorder, which should have put delivery early/mid January. I got the call today it was delivered to my FFL. I didn't even get an email letting me know it shipped so that was a nice surprise. I'll go down tomorrow and fill out the 4473 and take a pic of it.

Got one myself to go along with the "NukeMe-15" lowers from PSA.  Will make one of them an SBR I think and will be home to some "fully semi automatic" triggers. =)

I think it is at my FFL now.  Will have to call and find out.  Will pick up soon, hopefully along with my suppressors.
