relisted and changed:
bushmaster M4 flat top with J&T carrying handle. 16" BMP 1/9 barrel. bolt group is not included. $335 shipped (USPS money order). email me via ar15.com.
edited to add: I'm not sure of the round count, I purchased the upper used. Personally, I've shot less than 300 rounds through it with no FTF. There are marks on the gas tube (It appears the prior ower took it off as some point in time). The upper is used, but not abused.
