Used DPMS A2 upper receiver, unknown round count. Adjustment clicks are tight, it's mechanically solid. Looks like it was painted OD at one point. Rear lug is a little rough, but locks up tight to my STAG and RRA lowers. Previous owner said it required a shim in the barrel notch slot, I have not built or shot it. Would make a good upper for a truck/trunk gun. $80 FTF on the south or west side of Indy.wil
Will trade for new/ lightly used quality flat top receiver.
