The benefits and purpose of a Piston when added to a firearm in conjunction with a suppressor may be well known to the more experienced shooters but to those just starting out and looking to increase the overall performance of their firearm, then you need to know about combining pistons with suppressors.The Dead Air Ghost Piston combines well with Dead Air's superior line of silencers such as the Wolfman, Ghost-45M and the Primal with P-Series adapter. The job of the piston is to offset the weight of the suppressor. It does this by driving the suppressor forward ever so slightly while the barrel moves to the rear to unlock the action. The tiny bit of movement counteracts the suppressor's weight and allows the gun to cycle properly.Features: Weight is 2 oz Dimensions of 6 x 2.9 x 1.5 in Thread pitch of M13.5-1LH Caliber: 9mm Color is black Dead Air's Ghost Piston is easily interchangeable between numerous silencers and calibers,
