Jam nuts 1/2-28 source?

[Horilka]

Where do you guys buy jam (lock) nuts for 1/2"-28 threads? Usual suspects are out of stock, can't find anything on Amazon and Ali. Is there a chance I can find them in specialized hardware stores? Need a set of 4-5 pcs.

True North Arms has them for 11.00 a piece. I'm interested to know if anyone has seen anything cheaper

I needed some a few months ago and bought a 3 pack from range warrior accessories in calgary. The 3 pack is 19.99, they worked well
