Parma Woods is only a small step down from the new Lake City range. I went to Parma today.,
It's really not too hard to do. The sight tower is just kept in place with taper pins. Brownell's sells a polymer block that's supposed to make it easier to drive them out.
Do you plan to install a low profile gas block, cut off the site tower above the gas block to make it low profile, or re-install the sight tower after the quad rail's installed?
All that's likely needed is:
Remove the existing 2-piece hand guards
remove the muzzle device (hope it's not pinned)
drive out the site tower pins to slide it off
unscrew the barrel nut.
There's no real reason to remove the gas tube from the gas block if you'll be putting it right back on. By D-Ring, are you referring to the sling mount?
There are also options like the Daniel Defense Omega that don't require any changes to be made to the rifle. I don't have any experience with them....I've just read some info.
