A very strong, titanium valve seat bored out to 6.3mm rather than 5.5mm. Allows better airflow and more power when needed. Also, highly unlikely to break, and much stronger than the OEM Stainless Steel Valve Seat. Great addition for any power tune. Can possibly add up to 40 FPS, based on previous settings and caliber.
** Does NOT work for Impact Power Plenum, as it does not have a removeable valveseat**
Part of M14 Power Mod, and Power Mod w/o Plenum.
Designed by Ernest Rowe.
Designed to use a 8mmx1mm NBR 70 O-Ring. The Valve Seat will be sent with 1 O-Ring installed and a spare.
