Picked up a lot of a bunch of gas blocks in the EE from Hochimin (username) who is a Spikes tactical dealer. I assume these are blem spikes gas blocks.
Shipping is $5 for 1-5 units, $10 for 5+
10+ 3 .625 (lightweight profile) without taper pin hole remaining and Each gas block is $5 15+ 10 4 left .750 available that have the taper pin hole(standard profile)
All gas blocks have minor handling marks, may have minor surface cosmetic issues (minor tooling marks, slight surface rust), and will need the set screws.
Most of the gas blocks are set up with one tapped set screw hole and have room to cross pin or some of them have already been drilled for a taper pin.
I can't pick a specific one for you but if you want one that is or isn't drilled for a taper pin let me know.
These are fully functional steel gas blocks.
Actual pictures of the gas blocks that are for sale.
