Saber tactical everything on this as standard. I have also fitted saber tactical skeleton grip, adjustable valve return knob. Quick tune hammer system fitted so you can fine tune to your own pellet / slug choice. Also fitted is carbon fibre barrel stiffener to help with harmonics. Comes with x 2 mags (1 FX 1 eagle vision high capacity magazine). Duel gauges fitted also to read both first and second reg readings. Also comes with extra bottle ready to be screwed on so no need to carry air tanks. Had the rifle just over a month but won’t be using it now due to the type of shooting I have undertaken on land.
