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-STEEL Guide  quickly counters  movement deading spring firing noise. The Inner guide arrangment is machined slip-fitted into a helical guide that the spring fits onto, and the 4th guide "top-Hat" has the exact spring fitting pitch allowing spring a thread like firm tighter 360 degree 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, stiffer guide adding mass for better sound deadening.
