Dr.Black AGA Aluminium Guide Rod - 4.3 - Black HPA Set-ups these firing pin springs areNew From Dr. Black! CNC Aluminium construction 2 piece design allows for easy installation removal even with buffers installed Split Guide Rods will allow for more short strokes to be applied and an overall better feel due to the weight of the steel. Stronger material used compared to the Stock TM Guide Rod less chance of it cracking. This also supports a hollow end which allows the use of the very popular NexxSpeed Hop Up Units, increasing stability.
