Running a G32 and a G36 stock and loving it. I see alot of people putting in 3lbs triggers, mag extenders, slide lock release extenders, SS guide rods, stainless steel springs, ect. Has anybody found that adding a SS guide rod and springs actually helps out or is it mental? This is the one thing I could see doing and was wondering if it's even necessary. The other stuff I see as fluff but could be handy I guess.
