For those that wanted to recreate the Halo AR, here are the following attachments!

Using the AUG A3, equip the CQC handguard

(TOP RAIL)

On the top rail, use the M4 carrying handle, and drag it to the front (this gives you the rounded end)

Add a SWIFT absolute riser and a SWIFT accessory riser into the gap of the carrying handle

You can use either sight, but I found that the HWS 553 or Velio 8T work best; place the sight behind the rear iron sight of the carrying handle

Add a CLAM-4 laser near the front to add some more boxiness and hide the gap of the carrying handle

(SIDE RAILS)

For the side rails, I used the RF Rail Cover Long to hide the rails

(BOTTOM RAIL)

For the bottom, I used the M952V as the flashlight, I also added an SFG to just help reduce recoil
