3-lug adapter for my MPX Login/Join

Any surprises in store or things that I overlooked if I decide to go this way?

I've been looking hard at the Griffin Optimus system and one of the attachment configurations that it can accommodate is for 3-lug, which seems to be the "simplest"/cleanest way to use that suppressor on a MPX with its standard thread pitch.

Near as I can tell their regular (Griffin) suppressor-ready taper mount muzzle devices would require a 13.5 x 1 LH to 1/2 x 28 adapter before I can use their compatible muzzle device; to me that's extending things a bit too far beyond the end of my MPX's handguard.

Meanwhile I'd just put on a 3-lug flash hider while I'm waiting for my paperwork to be approved...

I responded but misunderstood you the first time.

Yes, I would got with Griffin 13.5x1LH 3 lug adapter and Griffin 3 lug option on the can for the MPX. That will be the shortest / easiest for the 9mm.


Straight shootin!

I have put the Griffin Armament 3-lug adapter on my MPX and it works with my 3-lug mount for the Omega45K and the TI-RANT45 with the Triad mount.

I have a couple of different 3-lug flash hider that I can attach when I don't have the suppressor attached (but I have the can on the MPX almost all the time).

Use Rocksett on the threads before attaching the 3-lug adapter, let it set and then you are good to go and not have to worry about the can backing off (one of the benefits of the 3-lug system).

Because of the outer diameter of he LH heads, the three lugs are much farther forward, past themuzzle, unlike with a 1/2x28 muzzle device. If you care about overall length, it is a little ungainly.

I cut my barrel to 6.5" and had it threaded 1/2x28. These days, there are some aftermarket barrels out there, and you can get 6,5" with the lugs, so I'd probably go that route, and leave my factory barrel unmolested.

I bought a 6” from ILWT for this purpose. It works very well.
