I have 2 HK 0,1,2,F complete. 40 lowers and 1 9mm one. I can swap out any to any cal for the same price, however the .40 housings have the bho. $575 each plus shipping via usps priority mail. These are very clear with great color and would rate at Excellent condition. Insurance is optional at buyers expense. All NFA rules Apply. Cashiers check, mo, PP 3%, cc is 3.5%.
