Ultralight Ultralight Rifles

[ezwy]

I've attached my dope chart for the BDC SWFA ultralight. It looks complicated... but with some practice, it's pretty close to dialing turrets in its precision and speed. Plus it's 100% repeatable because the only "dialing" that happens on the scope is the adjustment of the zoom, so you can't have a turret slip accidentally, or forget which revolution returns to zero, etc. Just get the range to target, look at the chart and find the corresponding zoom and line on the reticle to use, adjust the zoom, then aim with the correct part of the reticle... and shoot.

As for diy projects needing a mill, I was able to use a drill press for milling out the side charger slot. I made a wooden bracket to hold the upper in place, and used clamps to hold a guide to the table of the drill press, then I could run my upper in straight lines with a side cutting bit.

The most time consuming project was the carbon tube that had to be sanded on the inside to fit over the barrel nut. And making my fitting for the carbon tube stock to line up properly in the cutoff buffertube. But neither of those needed special tools, just a grinding wheel and sand paper.

Do you know the subtensions (mil or MOA) for that reticle?
Or what app are you using for that reticle drop info?

I can't remember which site I saw it on and maybe it's been covered here...

What about those super lightweight telescoping stocks that look like it might be like a brace? It looked like two carbon arrow shafts mounted into the butt with a bracket on the upper that allows the thing to telescope in/out

Not sure how light you want to go, but packgoatguys and my setup both have removable stocks that save a lot of money and weight. His pops off, mine threads out. Much more compact for the backpack as well

This is what I'd found

The steadybrace with polymer brace. I'm not sure if it includes the whole setup, but I think it'd be 3.6oz. and a whopping $175. That's not cheap. You guys' setup is probably the much better route to go.

That's petty light, I'm at 3.2oz, and I think PGG is right around 3. This includes the tube stub, tube and stock

I have experience with 3/8” Pultruded carbon rods in another application. They’re strong enough to hold me standing in one of them 30’ in the air climbing a tree.

I only have them in 6” lengths. But they can be ordered any length.

Have given thought to building a collapsible stock with them.


I just keep going back to whoever said it here - just unscrew the A2 buffer and stick it in pack or pocket. Screw in when you’re ready to hunt. Seems simple.

Strelok app

Here are the subtensions per swfa

A quick-detatch stock makes for a pretty compact package. With the foam cheek riser it's about 3.1oz, without the foam it was about 2.5oz including the threaded buffertube part.

Thanks a bunch! I guess I probably could have looked that up.
I don’t have strelok, looks like there might be a few hoops to jump through to get it on my iPhone. Gonna give it a try though.

Has it been covered on here how you did that because I really want to copy that! Wonderful idea

Hmm, I think I did... You're welcome to pm me if you want more details, but it was pretty much just a cut-off rifle length buffertube, a carbon tube, a carbon 90, and some 3d printed wedges to make a flat surface for the foam. I'd be happy to make one for anyone who wants, if they'd cover materials, shipping, and a bit for my time.

Ya, there is something wonky with strelok, I couldn't download it on my son's phone for some reason. I've had the app for years so maybe I have an old version or something.
