17-4 stainless steel heat treated and precision machined to fit the ODS Adjustable Gas Block, Combo Adjustable Gas Block and the PRO2ACE clamp on adjustable block.
There are 4 variants:
STANDARD- Same as what came with your original block
DIY - 5 1mm (.040") holes plus the blank location
HP - Optimized for high pressure systems like pistols and 556. It's basically the gap between smallest and middle holes, but spread over 5 holes instead of 3.
EXTENDO-Valve - This is the same valve but it is 1” longer to peak out of some combinations of block/rail. To see if this will work for you, put a ruler against your current valve blade and if you see any gradient under 1” ,it will protrude for you. Gives the user the ability to adjust on the fly with a bullet, gloved hand or other tool. Currently only available in DIY 1mm ports only for self tuning . For custom port configurations contact Pro2Customs for availability and pricing.
