Good price

FYI arm or ally pretty much always has them at that price also. Not on sale, just standard price.

Gues about ten bucks more now. Still good. I’ve got a few from here

$82.99 there for Carpenter 158

Ah vs the 9310 steel. Good catch

If anyone needs a cheapo for a grendel or arc build, Brownells has their house brand grendel / arc bcgs for 50 bucks today. Not sure who makes them, but I would suspect they are decent.

PSA also has complete Magpul MOE equipped lowers for $140

Best I can tell, their premiums are made by Tool Craft.

Not sure about their cheapo's.
