I want to replace the stock buffer spring system on this model. Which on would be a great upgrade to reduce recoil and drop right in with out any oth? — 1 Answer

I would recommend using the Geissele AR-15 Super 42 Buffer Spring/Buffer Combo. The Geissele Super 42 Spring was designed to improve the function and reliability of your AR-15 pattern rifle. Its unique spring design uses three independent strands of wire, just like the German MG42 Machine Gun. This concept acts as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your AR-15 more reliable. The Super 42 Spring has a 15% stronger average return force than the standard buffer spring. This will assist in stripping rounds out of the magazine when operating with a dirty weapon or when using steel-case ammo. You can find the buffer and spring combo by using the link below:
