Hi.

I have an MR223A3 (or MR556 for our US friends) and I recently replaced the stock flash hider with HK's rotex flash hider (#234182).

My old flash hider had a nearly perfect slot orientation (one slot straight up, one straight down). The new FH is slightly offset, so the slots aren't oriented like the old one. I used HK's official toque specs (45Nm and no crush washer).

Is this normal? Or should I use a shim washer to correct the rotation offset?

I should mention:
  • I have easy access to 0.1 to 0.5mm shim washers
  • I use the rifle for 100m precision scoped shooting
  • I have my reasons for wanting to change to the rotex FH, so no need to discuss using muzzle breaks, please.

Thank you very much.

Flash hiders with 360 degree symmetry and openings all the way around don't NEED to be indexed anywhere in particular. Some people get OCD about having the wrench flats oriented a specific way or having one opening directly at 12 o'clock or something. It's more important not over-torquing it to meet an aesthetic.

Compensators like the traditional A2 or a Surefire Warcomp can and should be timed to a specific spot. Unless the Rotex has to be indexed and timed for the suppressor, it's just aesthetic.
