I've got a 10.5" SBR that I'm looking to put a carry handle on. I can get an Aero Precision for $80, but I was hoping to find one for a little less money. PSA has been out of stock on their carry handles for a while now. I ran across Standard Mfg and they have one for $40 and it says that's made in the USA. Any thoughts on this: https://stdgun.com/a3-carry-handle-rear-sight-milspec/ Any other places I should look?
