This lightweight yet highly durable upgrade part for manual sniper rifles is precision CNC-machined from aluminum, ensuring maximum durability and precision fit. Two Delrin guide sleeves on the piston reduce friction and allow smooth operation inside the cylinder. The one-way vent holes improve air compression and boost overall power. This is an ideal piston for upgrade builds focused on performance, durability, and consistency. Please verify your rifle’s sear angle before purchase. We recommend combining it with other upgrade parts by Action Army.
