Strap / Flicker strap holder for Paradox 45
This part can replace the lid of a Paradox 45 muffler and allow mounting of flicker tape or strap. Pay special attention to the fact that when fitting a strap on the muffler, it is extra important that the support sleeve at the rear of the mufflers fits snugly to the diameter of the pipe. Otherwise the thread on the rifle and the muffler could be damaged.
