first off let me explain what i mean in the subject. i just got the guns from a friend and they need to just be cleaned up, check internals ect. well i am willing to buy and pre-install parts to inprove the base gun. the only catch is i need a 100% will buy befor i drop money into it (meaning leave a cash deposit) im only doing that to cover any runners, but since you will be leaveing money with me i will put whatever parts you want to install. i will tune and include free maintance for 30 days (in case something went wrong). so finaly here are the exact guns. DE UMP 45 with battery and one high cap, (i belive) CYMA AK-47 with battery no mag, and UTG (already upgreaded alittle) M-14 ACU color with battery and a high can (may have m-re in my box just need to find it).all prices are negotable and willing to sell as. if you have any question what so ever send me a pm or text/call me at 480-652-9630 (watch out for my voicemail).
