Colt 1911-22 Thread Adapter

The United Defense Colt 1911-22 Thread Adapter replaces the factory barrel nut on the Colt and Umarex 1911-22 pistols and converts the muzzle to the U.S.-standard 1/2x28 TPI thread pattern. CNC machined from steel with a blued finish, it threads onto the M8x0.75 factory barrel and gives you a true male 1/2x28 mounting surface for suppressors, fake cans, and other rimfire muzzle devices. A matching thread protector is included to keep the threads clean when nothing is mounted. Also compatible with the Walther P22, PPK/S 22, and S&W M&P 22. A must-have for 1911-22 owners running a .22 LR suppressor.

Features

  1. 1/2x28 TPI Male Threads — Standard U.S. muzzle thread pitch for direct attachment of suppressors, compensators, and other rimfire muzzle devices.
  2. M8x0.75 Female Threads — Mates directly to the factory Colt/Umarex 1911-22 barrel in place of the OEM barrel nut.
  3. Drop-In Installation — Removes and replaces the factory barrel nut using the original Umarex-supplied wrench, with no gunsmithing required.
  4. Thread Protector Included — Knurled thread protector ships with the adapter to keep the 1/2x28 threads clean when no muzzle device is mounted.
  5. CNC Machined Construction — Precision-machined for concentricity and proper bore alignment to help prevent baffle strikes on suppressors.
  6. Blued Steel Finish — Durable blued steel body matches the factory Colt 1911-22 barrel and resists wear from repeated mounting.
  7. Broad Pistol Compatibility — Also fits Umarex 1911-22, Walther P22, Walther PPK/S 22, and S&W M&P 22 rimfire pistols using the same barrel thread.
  8. Suppressor-Ready — Purpose-built to run .22 LR rimfire cans and other 1/2x28 muzzle accessories on a host pistol that ships without threaded muzzle provisions.

    Put this on my Colt 1911-22 so I could run my suppressor. Threaded right on with no issues and the protector is a nice bonus. Went to the range same week I got it and everything cycled fine. Great little add on for the price.

    Swapped out the factory barrel and this thing threaded right on no issues at all. Took maybe 30 seconds to install and my suppressor mounted up perfectly with no wobble.

    Been wanting to put my 1/2x28 can on my Colt 1911-22 forever and this adapter made it super easy, just swap out the factory barrel nut and youre good to go, took me maybe two minutes in the garage with no special tools. Fit was snug and it threaded right onto my suppressor with zero wobble.

    Overall though this is EXACTLY what I needed and its solid quality for the price.
