During checkout choose the option with the 90 days layaway. You will need to pay minimum 20% of your gun purchase and have to spend minimum $300. To get the cash discount you will need to pay echeck or send a check or money order. If you do not pay within the 90 days your order will be canceled and you lose all the money you already paid.
As for the MK25 I just checked and they got it instoforay buds for only $885 shipped. As for the 15rds mag, Sig had blocked the mags to feed only 10rds.
so you can pay any amount as many payments during a 90 day period? i think i may jump on this then. OGCs price was $890 for the mk25 but out of stock now
