Ultralight Ultralight Rifles

5x PA Microprism with the vertical spacer (no offset) was 9.5oz on my scale.

In regards to the swfa 2.5-10x32 UL (BDC version) I've had good luck with them. Very easy scope to get behind IMO with a very bright and wide field of view considering its small size. I've found a trick with the BDC/SFP combo that works for me... I use it like a poor man's dialing scope. Basically, the different power changes the subtensions of the reticle, which I use to make a custom dope chart. Basically, from zero to 600 yards there is a combination of zoom and one of the ticks on the reticle that I can combine (within 3 yard increments) to get me a precise holdover. It sounds complicated, but in practice I find it only a second or two slower than my regular dialing scopes.

My Shaw portless is doing alright with AAC 77 TMK. 1.5” is about average for 5 shots. Some of that is me getting used to the light weight and trigger. I did have one group about an inch not counting a shot I called as me.
Hoping as I get used to the rifle it can do a little better or I might need to load for it.
I did go 3 for 3 on a 300 yard gong pretty easily.

The AAC ammo has impressed me. I use the 77g OTM in competition to 500 out of my Geissele with good results.

That said, I'm gonna be loading for mine. I have a ton of primed 223 brass from my High-power days that I need to use.

Thanks for the thought on this. My biggest problem with the 2.5-10 is using it on 10x as the eye box gets too critical for me. Just messed with strelok a little and I can get the reticle to be pretty close out to 400 yards using 8x. Falls apart a little beyond that, but I rarely shoot further than anyway, and turning up to 8.5-9 pretty much fixes those ranges.

A bonus is 8x actually lined up better for my new 88ELD M load than 10x. It's pretty much right on out to 550. Haven't shot it with the SWFA yet, but looks like it will work well.

Working on a project to ease extraction and chambering. I got an aluminum bolt knob from Ebay and slapped it on - its huge, so I might shorten it, but I also really want a 6 ARC and wonder if this might make it doable. Definitely increases the odds of knocking it out of battery, but we'll see how it goes.

Anyone know of a 20" lightweight 6 ARC barrel?

Bringing this back up for the extended bolt knob inquiries. If you message "kitascreations" on ebay, he'll customize the hole dimensions. I requested a .190 through hole and a .350 countersink 0.25 deep on the back side of the knob, but then ground the knob a little shorter and had to open up the countersink for the 10-32 screw I used (use loctite!). It's aluminum, so not difficult to customize.

I cut off and used the neck of the original Solo bolt handle to fit between the bolt and the new knob. Plus he did it all for free and the knob was like $20.

Here's the final product now.

And does it cycle a 6mmARC spent cartridge reliability? Easily? Comparison to .223?

Haven't tried it. My biggest concern though is all the stress that it places on that small 10-32 screw in the aluminum carrier.

I'm using a looped, looped flat piece of cord (like the outer sleeve of some paracord) with something tacky on one side, like shoe goo.

You can see it in most of my field pics. The loop cinches against itself under weight and doesn't slip, but is also super easy to adjust, move or remove.

I did this as a stop-gap measure on my first Kaw Valley handguard, but it has worked so well that's all I use now.

Like Taudisio said, a hole (or two for a loop) would be really simple and more permanent if you want that.

I'm trying e6000 that ends up rubbery when cured on 550 and something a little wider to try with a boonie packer sling I already had.

E6000 is actually what I use. Works well. Have tried liquid tape and silicone as well. Liquid tape is okay, the silicone didn't work well. Maybe if it was thinned and penetrated the into the weave more it might work.

That's good to know. I've used it for years to put bottle opener inserts into hockey pucks that I drill out with Forstner bits. It cures nice and tacky. I'm interested to see if there's any practical difference between the thicker webbing I had in my "rope drawer" and 550 cord with the middle strands removed in regards to how well it "holds" the carbon fiber tube.

What silencer are you guys using on these? I have a Gemtech Tracker that I just weighted at 11.1oz. the adapter to mount it on a 1/2"-28 barrel is 1.6oz, so 12.7 total.

My Polonium (non k) is 13.5oz.

It's gonna be interesting to see POI change with/without the can on such a light barrel.

I don't think anything is lighter than the TBAC Ultra 5. I wish they made a shorter, fatter 223 version.

So, he did not machine the neck into the bolt handle? I could see that as a weak point since the bolt is spanning that distance.

If I CAD out an extended bolt handle for Kita to fabricate, would anybody else want one?

I take back my comments on the bolt being overly difficult to operate. A little gun oil and it's great. Put 5 rounds through it on the way back in from the trap line. Easy peasy! Just need an optic now

Nosler sr-30k is .4oz lighter and that’s what I’m running. I don’t know the weights of the adapters though. So close together it probably doesn’t matter. The I paid about half the price of the tbac for the nosler, $550.

 

[goalie]

I'm going to get this built as soon as the Solo 300 action is available and try it with my Gemtech Tracker. If it's right at 5 pounds suppressed, I think I'll just keep using what I've got. I have a heavier Griffin Optimus that I can throw on my single shot 30-30 so my son and I can both be "quiet" while hunting at the same time, or the Gemtech on his 6.5 Grendel and I use my Polonium on the ULUL AR.

I haven't even seen that one. Looks sweet.

I'm still holding out for a 4", 6oz 224 cal suppressor.
