I have a shooting innovation aluminum carrier. Guess they don't sell them anymore. Never used it, although super light.

My lightweight rifle has the JP aluminum carrier, it IS crazy light. Highly recommend you pair it with a New Frontier polymer hammer/trigger group with it. Originally I had a velocity trigger pack and even with a curved tip on the hammer it beat up the bottom surface a bit which is why the JP states that their aluminum carriers have a limited lifespan. I sanded it back smooth(ish)/took out the bigger bumps after I replaced it with the NFA kit and the polymer hammer hasn't done anything to it.

Figured I'd post up here before the EE. I have a Halosun HS503G w/ACSS reticle on a absolute co-witness Fortis F1 which a swapped the steel cross bolts for Ti. 4.2 oz for the whole shebang!

Low mount and lower 1/3 also included

I got it all set up and went out to shoot only to realize my astigmatism was worse than I thought. Still usable if I look through a rear peep sight but I'm getting a Primary Arms GLX 2X to replace it.

I'm looking to get $230 shipped for the whole setup. That's what the going rate seems to be for a new HS503G and you get the UL mount for free!

I'll take this.  Email sent.

Got in one of the KE Arms KP-15 lowers to try out on my lightweight build, and I gotta say, I like it a lot. Dropped the weight from 5lbs 1oz to 4lbs 14.5oz without mag or sling. I prefer fixed stocks anyway so it feels like a no-brainer for me.

withoutremorse42 do you still need some of those lightweight parts for your build? I havent checked the forum in a couple days.

@mnkyco

I still need a Luth-AR 601 triangle CH DSA Low mass Sand Cut BCG and a Ti grip screw, but I'm down to strictly trade mode.  Already went WAY over budget for this article

Ok, I IMed you.

Anyone have the weight of the X-15 HXP skeletonized drum magazine from X-products?

after a great trade with @mnkyco I'm down to 3 lbs 3.3 oz for my rifle.  Still have a couple small parts I can swap out, but I think I'm just about as far as I can go without drilling.  Dont think I'll make it to sub 3lbs.  It will be in the 4 lbs range with suppressor and optic though!

Have you shot it yet?

Maybe in a couple days.  Just had hip surgery so I'm not walking well.  The barrel was on a previous build and was fine, but not amazing.  I'm hoping this build agrees with it a little more, and now I have a wider selection of ammo to try out.

That was yesterday, felt froggy today.  Shot it and got the adjustable gas block dialed in.  Went unsuppressed until it cycled, opened it one click more, then ran with suppressor.  Ran well with cheap russian crap.  Next up is zeroing and grouping, once my hip is healed enough to shoot prone.

Absolutely laughable recoil.  Not that .223 has a lot to start with, but this was just a hair more than my 10/22.

The 3d printed buttstock is still very much a prototype.  I opted for the buffer tube with no boss on it, so the stock is free to spin a bit despite being bolted down as tight as it can be.  

The DSA BCG, tubb flat spring and taccom 3g buffers are an awesome combo.  I suppose I should put the SLR gas block in that list too since that's what's balancing the force-to-mass ratio.
