Crushed Nubbins Anyone?
Does anyone have a problem with the little nubbin in the hop-up on armalite V2 with both systema or Guarder metal hopups getting crushed after very short use? If so, do you have any observations or advice? On two guns I have an ongoing problem with this - I put in new nubbins and within a *very* short period of time (one month?), the hopup no longer functions... I am pulling my hair out of my head...
