HK PARTS AND ACCESSORIES FOR SALE
Recently bought this, I have a 11.5 inch HK MR556 and figured it would fill in the gap compared to my 10.3 Geissele rail. Even though it says 11 inch it is actually the same length as the Geissle rail. I'll ship it out for $175 including shipping via Paypal.
Only was mounted and not used after...
