So late last week, I finally went from this:
To this:
Notice that I have moved the aft UBR sling cup to the right-hand side. This allows for reaction-hand transition without the sling passing behind the stock:
I put adhesive velcro on the case deflector and ejection port cover stop to protect the finish. I did this on my last AR and it performed its intended function very well:
I had to get creative about protecting the rails around the rear sling mount sockets and rail's cap screws since the XTMs wouldn't go on:
Note the relief on the ladder cover performed with an almost-sharp-enough Leatherman tool:
Here are the relief cuts for the rail's cap screws:
I had a buddy sand the side XTM panels down to allow the ARM-R top rail to be removed, as the picatinny grabbers had interfering corners. The VLTOR bipod also allows clearance, so I can remove the top cover without removing any accessories:
UBR and bipod stowed:
The LWRC M6A3 upper is awesome. The one-piece bolt carrier is a piece of art. The IR cover on the light is just a pressure switch safety, as the LED plus the cover puts out negligible IR light and is effectively almost opaque. I had the cover and decided to put it on.
I'll Duracoat the upper later to match the lower.
