Manufactured STEEL Body PRO-GUIDE4 STEEL tune kit provides another level to damping.
With its new mass, weighted rear retainment guide, stiffer beam strengh the new PG4-Guides STEEL quickly counters movement deading spring firing noise. The Inner guide arrangments are machined slip-fitted into spring as well also the 3rd guide "top-Hat" has the exact spring fitting pitch allowing spring a thread like firm tighter fit apond firing. The spring with open coils allows use of all coils for more accurate output across product line. Further, the DiY tuner has option of cuting spring for finer tuning. The new PG4-Guides have a near fit to its power grid with a heavier guide adding weight, beam-strength for spring equaling less fatigue, better sound deadening.
