I've got an HK USC .45 carbine that I'm looking to trade or will sale for $1200. It has a Top Notch grease gun conversion along with 30rd gg mags. Also comes with the original lower and 10 rd HK mag. I planned on doing an ump sbr clone, but don't have the extra cash. Here is a pic I have on my phone, if you need more let me know. Thanks
