Title says it all. I have a 10” MK1 that’s in awesome shape. I also have a 10” 416 rail that I’m looking to sell or trade. I’m looking for a 13” Geissele MK1 black or preferably ddc, sand, darker anodizing. Pictures upon request. Sale prices are $375 for the HK or $400 for the MK1 shipped via PayPal gift or you cover the fee. I can also do Venmo. Email is best for contact. Thanks!
