Jackalope33B Posted June 8, 2010 Share Posted June 8, 2010 Hey Benelli owners! Im new to the forum, so please bare with me. I just bought a M4 the other day, and Im looking to upgrade it. I want to add the bigger bolt handle, mesa saddle, bigger slide release button, either 2 shot extension OR full length magazine tube, and a picatinny foregrip. What is everyone using? Im at a stand still between a KZ rail and a Brugger and Thomet rail. What exactly is the pros and cons of both? Is there another rail out there that will compete with these two?
