chris2022New HK MR556 A4 clone lower receiver . These will work with the HK ambi parts . This is is just the stripped lower and you will need to purchase the HK parts to complete this . The real serial number is hidden under the trigger guard . Yes these are forged and the same style as the original. The measurements were taken from a original HK and duplicated so the lower has the authentic look . They are color filled so no need to color anything, just assemble it .
