Simplified piston gas block is designed for our NYLAUG barrels and 3D print builds
KAK piston design uses AR15 gas rings instead of AUG size
Single non adjustagle gas setting
Excess gas after stroke is vented down
Set screw attachment matches the dimples on KAK NYLAUG barrels
This is a complete gas block assembly as seen in product picture #2
Worked great for me, had to modify and reprint the handguard I was using to fit so be aware you may need extra clearance. Way simpler and more solid than modifying the factory gas blocks, very impressed to see KAK supporting an interesting niche project like this. KAK nylaug barrel was also more accurate then I was expecting. Maybe we'll see more barrel options someday? I would build an 18-20" 17-556 aug if the parts were available.
