Cleaning out the garage a little bit:
Oerlikon 20mm mags, rusty and one of them has some dents - but they are intact. $100 for all of it, shipping is not included - be happy to meet within a 30 mile radius of Fredericksburg.
PPSH41 barrel - dirty but it great shape, original Russian, chrome lined. $100 shipped
ARMS rail for the AR10 - tinkerers special, missing the clamp and maybe other parts - what you see is what you get, $20 shipped.
Always up for trading, parts kits, machine tools, M249/MK46/MK48 parts, really would like a CETME-LC kit.
