First build I just finished. 5lbs 13oz.
I didn't want to go too light. Upper is an Aero without forward assist.

looks great.

truth be told i'm actually considering paring down my collection and my ultralight is on the block.  at 4.6 pounds, the comp is *TOO* efficient and the muzzle dips on every shot heh.

it's tons of fun to shoot but i find myself running drills with the 5.6-pound rifle a lot more as it's just a little easier to keep on target.

ah well.  we'll see.  i'll probably chicken out and keep it to avoid sale regret.

I'm actually gong to throw a chunky 1-10x on it. The weight savings should balance out

Maybe start a lightweight 308 thread?

So, did some changing around on my lightweight build, which brought it up to 5lbs without the mag:  

Swapped out the Brigand Arms CF stock with a normal rifle buffer tube and the Luth-AR Skullaton stock. Also swapped the RTB lightweight carrier and BCM 3x3 ambi charging handle for a JP LMOS and Fortis Clutch, respectively.

I’m not big on the new math, but I think 8 pounds, 13 ounces is WAY over six pounds. That’s Garand territory. Nice piece, but maybe not the right thread, huh.

I’ll bet without the thermal, suppressor, and ammunition it’d be pretty close.

This year has been a bad year to build a high end lightweight 223. The goal wasn’t to just build a super lightweight rifle, but to build a reliable rifle that isn’t stripped of features.


V7 2055 upper, 14.5” Proof Research carbon fiber wrapped barrel, JP Enterprises LMOS bolt carrier group,V7 magnesium hyperlite rails that titanium mounting hardware, SLR titanium gas block, V7 inconel gas tube. B. E. Meyers 249 flash suppressor,RailScales KOS G10 rail covers, Modlite OKW weapon light on a Modlite light body. Scalarworks absolute co-witness RMR mount.

The lower is still in parts, but it’s from V7 in the 2055. Receiver extension is carbon fiber. Small parts rug thru Foward Control Design and V7 parts. Geissele trigger pack.

All applicable parts are being sent out for NP3 plating soon. Plastics will be OD green and some items will be cerakoted OD green to match.

Great build.

Thats the first Master of Arms mount I’ve seen other than on their website, very nice.

I have a FF grip on one of my AR’s, my favorite grip by far.

Compared to a steel one it saves 1/3 ounce for not much money.

Compared to no end plate it weighs 0.15 ounces, but would prevent stock rotation if the castle nut came loose.

I tap my receivers for 4-40 grub screws to retain the takedown pin detent spring, and thought about leaving it off.
