This is a lightweight build I put together about 2 years ago. Complete DPMS Oracle upper 4140 1/9 with a polymer lower that I put either a DPMS or CMMG standard trigger group in. Complete Magpul furniture including FG with a Magpul QD sling mount added. Low pro gas block, front site is removeable. Rear BUIS is a sturdy steel pop up HK style turret with apertures for various ranges and nighttime. Irons co witness through the optic. Receiver end plate supports ambidextrous sling mounting. This rifle has been shot a fair amount. I have taken a couple of courses with it, one in the rain and mud (no rust!) and it has never let me down. Round count is no more than 2 - 2.5k I estimate. $500 without the TRS-25, $550 with. Need cash no trades. Now $450 and $500.
