Bud's gun shop has the 20" for $550 in stock.
I just sent this email to Bushmaster.
How much longer will I have to wait for this unit to arrive? They are for sale elsewhere and while it was a good price I'm kind of getting tired of waiting. I didn't know that you didn't have them built at the time I ordered. Your website listed them for sale and I took for granted you had them ready to ship.
I appreciate your quick response as I decide on whether to cancel this order or not. I would rather not cancel if at all possible.
Thanks.
