H&H sells them for $150? I'd buy it at that price - they're $169-$175 nearly everywhere online.
FYI, the Primary Arms M3 is around $69 and you can pick up a Micro with QD Base for $138
They actually are $169 at H&H. I said $150 because that is what s saleman from the gunsmith countert told me on the phone when they were out of stock. I noticed this the other day when i saw they finally had them in stock.
