Wow, I don't know what the hell's going on with that sniper. I love the look of the new BR, and I've gotten used to the DMR after seeing it in motion, but I don't know if I'll ever likt this new sniper. It's cool that someone wanted to add an actual scope somewhere, but... that's not how I would've done it.
I think my problem is with the fact that there's just one solid block with the scope, and the screen, and a bunch of other junk attacked. If the screen was separated from the main body of the scope, it might not look so awkward. Now it just looks like a huge brick with a bunch of stuff taped on . Also the bolt is a really big, awkward shape. Also that square rail thing on the left is an eyesore. Also that cable on the right of the scope looks liek it belongs on my parents' landline phone, not very futuristic.
Hopefully the canonical context for the sniper is that the UNSC Infinity was celebrating "Bring your 23rd Century Antique Weapons to Work Day" when it lands on Requiem.
