TPM (Thread Protector, Muzzle devices) for 0.900 x 24 threaded muzzle devices / suppressor mounts such as Plan B, Rearden Manufacturing, Liberty Precision Machine flash suppressors comps and brakes, etc.. Two versions are available: TPM-F (with wrench flats), and TPM (sans wrench flats)
Machined from solid bar stock in 4140 steel and black nitrided, TPM has widely spaced flutes to assist installation and removal. TPM-F has wrench flats for a 7/8 wrench for when the thread protector refuses to budge by bare hands.
Proudly designed and made in USA.
NOTE:
Q's new Rearend muzzle device is different than the previous versions, TPM and TPM-F will only partially cover the threads. Below are pictures from a customer showing the difference.
Left: original Q Cherry Bomb. Middle: new Rearend Cherry Bomb.
In the second picture, TPM partially threads onto the Rearend Cherry Bomb (middle), and fully threads onto the original Cherry Bomb (right).
We're working on an updated version that will work on both the new and old Q muzzle devices. TPM is still functional on the new Rearend versions even if some threads are exposed, TPM works as a fence that prevents the exposed threads from contact and impact.
