the second build is officially on 28 inch ELR build

[mel]

its a dtt branded billet upper noy sure who actually makes it , but ive bought some dtt branded parts before and it was all decent stuff , worst case is its not that good and i can change it later when parts availability comes back , im sure i was lucky to find the one i did , infact right after i bought it it went out of stock on there site the next day so i either got the last one or close to the last one
