Ultralight Ultralight Rifles

[BREAKCONTACT]

In regards to the lightest possible (non AR) bolt action rifle build... theoretically with a titanium or skeletonized action, 17oz including bolt and trigger is possible. A 13oz stock is possible. And if a 17oz 16 inch pencil barrel works for an AR15... maybe someone could make one that lightweight for a kimber or Rem700 style action. So...

Theoretically:
17 oz bolt/action/trigger
17 oz Barrel
13 oz stock

That would be a 47oz (sub 3lb) bare bolt 223rem action rifle.

However, I think the bottom end of the 223rem AR15 bolt rifle ULUL possibilities is under 2.5lbs, maybe even 2.25lbs with a full 16 inch barrel. So, I doubt it would realistically be possible to beat (weightwise) the AR15 platform with a traditional bolt action rifle.

So after combing through the parts weight database, just looking at the posted numbers, a 37 oz build is possible just buying off the shelf stuff, but that begs the question, is sub 2lbs possible?

Well, the Shaw portless barrel certainly shot Sierra Tipped Matchkings well-- better than such a tiny barrel should be expected to shoot on an AR platform. Shot the 10-shot group below yesterday. Probably capable of an even tighter group if I used a finer reticled and heavier scope (center dot of the Nightforce 1-8 I used is larger than the sticker I used for point of aim). I was hoping for a 2 MOA group; this will do nicely.

X caliber 20% off right now.

Mine didn’t shoot any different than my Shaw. Five minutes with a 2-64 tap and cap screw and rocksett and the port is closed. You could buy 4 of these for price of the Shaw.

And it’s lighter.

Yeh the Shaw is the answer. But this is stupid cheap.

@KyleR1985
Thanks to you, I now have 4 barrels for one gun, and I appreciate it!
-kept chasing lighter & better...

Will these "tapped" ports still work with standard gas blocks if we want to later remove the plug and make it a gas gun?

Another edit: from the looks of it the 5.56 can be loaded longer, as I wanted to run at least 2.36, but the Shaw and green mountain are barely longer than 2.25.

Does anyone know if you ream a 5.56 longer for heavies, does it remove the throat, so you can then choose 223 or wylde throat? Of course tons of people have gone the other direction, but I can't find anyone even asking the question anywhere. I wouldn't do this unless it shot poorly and my Smith said it was because of the throat/he could fix it...

Buy 4, pick the best shooter, sell the other 3 for 35 apiece?

I found this stock last night and had to share--4.1 oz and $125. A lighter castle nut or redesigned part with no castle nut could drop that weight lower.

It has me thinking I need to get a 3D printer. I've long been on the fence, and this might be the item that pushes me over.

I'd like to know where it's out without the nut, foam pad, and if you want to get really crazy I bet you could use glue instead of the top 2 screws.
Pretty easy to get the carbon tube+farrowtech to 3-3.2oz, but this might have much better ergonomics. I wish they listed a LOP!

LOP is 13.5 but he said on the video you just cut it to what you want.
