Hi , I just dismantled my D54 to replace the breech seal. I have taken the gun apart several times for various reasons . I took photos as a reference and thought I installed the steel and rubber washers correctly but now I’m not sure? The front (closest to the front sights, ) has 3 , arrangement being steel , rubber , steel and back (closes to trigger) has 2 , arrangement being steel , rubber ( rubber on top, steel on bottom) . However I did a quick search here and found a post by dtdtdtdt, Jan 31, 2020 in which he states the arrangement should be the opposite being 3 in the rear and 2 in the front? I believe he is an expert on this gun. Perhaps I’m misinterpreting his post? I then looked at a parts diagram and there appears to be 3 washers in the front and two in the rear in the same steel / rubber sequence as previously indicated. Not sure which way to go now? I would greatly appreciate some clarification on this, Thanks Al
