I have a genuine 10.5" Factory HK upper. This upper has had 840rds of 55gr. LC M193 put through it; but has been maintained and cleaned thoroughly. Asking $4K. I am located in Kerrville, TX but will drive to San Antonio. Pictures will posted later today. No trades. Cash or certified funds only (PMO). NOTE: This is an NFA item and may only be put on a LE/SBR/NFA Registered select fire lower receiver or a pistol configured lower (NO STOCK). Serious inquiries only please.
