Gator - Centurion looks nice. The issue is that this build started with the $169 version of the DD m4 barrel (on sale at bcm) to the $230 BCM midlength.. to the $299 BCM CHF... then to the DD CHF for around the same price. I may honestly just go back to the std BCM midlength barrel as that might just be the right mix between cost and performance for me. Still undecided though.

SDDuc996 - I'll definitely be giving DD a call about their barrels.

Stickman - Any specifc reccomendations for eye and ears for a guy who already wears glasses? I have an astigmatism though so I can't always get lenses made for frames with high amounts of curve to the lens. Budget for ear protection is ~100 or less for active electronic muffs if possible.


As for the rail system I might have to give DD another look. The reason I liked larue's rails is the mounting system not allowing the barrel nut to be loosened by any torquing of the rail by a VFG or other attachment. One thing to consider for this build is that once the FH is pinned on the barrel nut and gas block will be pretty much on the barrel forever so I am trying to make predict my needs down the line and also make sure every part of the upper (gb/area under rails/barrel nut area) is accessible without the removal of the flash hider/gas block.
