I have a bushmaster factory lower with a cav arms a1 stock on it. I painted it and then took the krylon paint off. It still has a little on it. It has about 500 rounds on it. I am looking for mini 14 30 rounders but would take some 20 rounders. They have to be factory ruger no exceptions. I can email some pics of the lower. My email address is email@example.com The lower has to be sent to a ffl a original ink copy will have to be provided before shipping.
