Ultralight Ultralight Rifles

[Trackselk]

For reasonable cost, simplicity, and function, I'd start with the first build in this thread with a couple of changes:

1. Shaw's unported 223 Wylde barrel (wasn't available back then - thanks to @StupidLightweight and the people in this thread for making that happen).
2. Either a Kaw Valley PCC handguard of you choice (relatively inexpensive and very functional) or if you want something a little lighter still, one of the homemade versions people are doing here. (My 9" handguard is only 1.9 oz and probably 1/3 the cost of the Kaw Valley and just as rigid)

I would add that @hereinaz is about to have us a lighter barrel than the Shaw, and more people's buy in will help make it a reality. But you'll have to be willing to wait approximately 2 months.

Just the Stand1 77tmk I've got. 2750fps

How is the Stand 1 77 TMK shooting and what barrel?

This looks awesome.. To save me from reading through 157 pages, can someone summarize the go to Rokslide build here? What is Rokslide's go to upper? barrel? forend? stock? Keeping value/price in mind

Many of the uppers are being build on the “solo 300” though many others are using other uppers and adapting as able and needed.

The @Thegman answered the barrel and forend question.

The cheapest (I think) folding adapter is the one from “military overstock”, but there are quite a few out there. There are some lighter ones but they are expensive. This is a luxury and not part of the original ULULs but many have added these in.

The stock is a variable. The cheapest is just using some carbon fiber tubing and developing your own including a buttstock. There are so many options in this category I’m not sure where to begin. I went with the CP prebuilt one but there are definitely cheaper and as equally light (if not lighter) options.

The hogue 15 degree grip is probably the best all around value grip you can get. Light and affordable. Not much else that I know of that competes.

It's shot well in the several barrels I've tried: faxon, shaw, and BCA.

My first pistol build is 4 lb on the nose with Ultra 7 and Holosun sight. No modifications yet, except an A2 buffer tube I already had cut in half.

Its a relatively heavy 5.56 12" barrel with Bear Creek Upper and TA lower. I will add other details when its done.

Looking forward to shooting it.

The farrowtech stock needs a rifle length buffertube (you can use a carbon fiber tube to shave another ounce if you are interested)

Pack goat I like that for grip with integral Arca. What did you start with for the Arca piece?

Packgoat, thanks for a new purchase, how much does the 90 elbow from rock weigh?

Packgoat, thanks for a new purchase, how much does the 90 elbow from rock weigh?

The listed weight on their website is pretty accurate. I weighed mine at 32 grams.

Just know it's not a tight fit in the proper sized tube, so you have to build it up with some epoxy or a spacer of some kind.
