[QUOTE="kfd518, post: 2903294, member: 125515"] The +2 is going to give longer for gas’s pressure in the barrel to drop closer to designed operating pressure and timing of the unlocking of the bolt. IIrc most of the short mags have issues with breaking extractors. The biggest reason for this is too much pressure still holding the brass to the chamber at time of unlocking. Buffer weight and spring rate can help this but I don’t know about them FIXING it. Depending on journal length you could have it drilled for a GB 1” further away and possibly get your +3” [/QUOTE]
