I'm interested in building an extremely lightweight AR for hunting and trapping in the thick Maine woods. I just finished a long range AR and it weighs about 11 lbs. It kinda sucks for lugging through the woods. Im thinking about these options as i would like to have no compromises on weight:

Barrel: 10.5" Noveske N4 w/ FSB

Upper: not sure, im going for less weight, but dont know if a carry handle upper weighs less than a flat top with a flip up sight, im not worried about optics because i will most likely always have open sights.

BCG: Young MFG National Match Light

Fronts Sight: FSB

Forearm: Magpul MOE

Flash Hider: AAC Black Out

Lower: not sure, billet or forged, if forged is lighter id go with Noveske, if billet, maybe POF gen 1, TKS, or Tactical Inovations

LPK: CMT or Armalite

Grip: like the MOE or MIAD, but probably stock ar grip would be lighter?

Buffer Tube: VLTOR

Stock: lightest possible, maybe VLTOR Clubfoot, LMT, MOE, M4 collapsible?

Charging Handle: BCM Gunfighter, any lighter?

Rear Sight: possible carry handle upper? if not try to find the lightest rear sight. maybe Magpul? Suggestions?

In your opinions what is the lightest weight achievable? Possibly less than 7 lbs?

Any help would be appreciated. I'd like to know people's opinions on the lightest AR parts and accessories.

Thank You
