I found 1/4" set screws somewhere, the Home Depot maybe, but that's the smallest I've seen, and that's too big to fit.
McMaster Carr has them, of course, but I'll check Pep Boys and one more shop before I give up and mail order.

I had a hard time finding 4-40 set screws for may AR lowers and ended up buying from McMaster Carr. The Part Number is 91375A103. If you only need a few send me note and I can mail you some. Otherwise just order 100. Its cheap enough.
