Great guys ,Yes, I completely understand Top Hats & Buttons are two different Mods aimed at solving different shot cycle issues.On my Hatsan 95's & 135, when Top Hats are added, I was going to remove the lower (black plastic) washer on the spring guide. This leaves only the metal washer which should give me the needed space for the Top Hat w/o increasing spring tension (I hope).The Top Hat mod is to help remove the guns (twang or jerk) when firing. My original question (worded badly) was to ask "which idea has more value for the shot cycle of a magnum springer?"
