TTI MPX Stock Adapter

Looks good fits perfectly only thing I would change is to make it easier to take on and off

Worked perfectly on Ruger PC 9. Great quality.

A solid and stable mounting point to add a V-Seven heavy steel buffer tube and BCM MOD1 Stock (in addition to a Smoke Carbon hand-guard), it greatly changes the center of balance and handling characteristics of the Sig MPX.

I have used this now for all my Biden builds and it's fantastic. I do wish the set screw was a little bit bigger to help center the extension tube in the threads channel. Otherwise, it's perfect.

Yes it fits the Ruger Chargers, including the 9mm PC Pistol! Have used this and the KAK, and the only reason I will give it 4 stars, is the Taran is a little harder to remove if you need to, as you have to undo your brace tube to access your fastener vs, the KAK with it's external fasteners. A tip for you when installing, Take the small screw out and apply some purple loctite to the threads, and some blue to the main allen screw so they don't rattle loose over time, and don't get crazy on the torque, a little goes a long way, just get it all snug! And milspec or comspec buffer tubes, use the same thread pitch, so any AR buffer tube will thread up, the comspec is just a weaker design...

I am just trying to find out if it is mil spec or commercial spec threading?

Bought this so I could add a AR like buffer tube and stock. Worked great. Only negative comment I have is that you'll definitely need Loctite to hold it in place and getting to the threads is a little tricky. Wish it had a bolt, that ran into the base of the MPX. Works well though. Added a buffer tube and lock nut from BCM. Fit like a glove.

Very well made adapter. Installs very solid and easy (without buffer tube installed). Very good quality.

It’s clean simple and well worth the price.
