Ultralight Ultralight Rifles

[HighUintas]

Any new records for low weight or new developments for the buttstock?

I haven't tried to get below the 2# 10oz rifle I built last year, for personal use anyway. Not sure if anyone else has gone beyond that. @packgoatguy ?

 

[ACHILLES]

I think pack goat guy was at an impressive 28oz without can or optic with a 10” Bbl.
No sling needed, he probably carry’s that thing in his front shirt pocket.

 

[HighUintas]

Wow. That is impressively light. I still want to build one at some point.

How do the 6x45 barrels function with that solo upper? Any extraction issues?

6x45 will extract fine

ARC has been extracting fine for me. I haven’t run with my 6 or 22 ARC on a Solo which is tighter and harder to cycle. I’m using a BCA side charge and Warwick tactical side charge.

ARC barrels are not as light as 6x45 but you have better bullet options with factory ammo or brass available.
For a bunch of money I think you could get a 22-23 oz ARC barrel 16”. 30 oz is easy and cheap, 27ish is the lightest readily available I have found.

About time to head out. The UL-Dmr (20" bbl, <6#) on the SO flight 3 pack is going to be perfect for my run and gun scouting....in case a bear or lion shows up.

Took it from 200-500 yards last weekend and that 5x with the BH tmks are money.

Sure beats the 14# gun i was trying to carry last year

First blood was a spike bull, no pics, but the 4lb (as pictured) rifle then got me by best buck by far:

Phenomenal. Mind if I share the photo?

Go right ahead, thanks for the solo300 action!

Fantastic buck, great job!

What are your barrel and load specs? Range?

Thanks! That was with the cheap bca 16" 5.56, and DRT 79 grainers going 2650 (slower load that printed well, I was in a rush pre hunt) at 125 yards

I got an email from Bear Creek Arsenal and see they have 22 ARC uppers and barrels now. They also have a statement when looking at barrels that they will hold 1 MOA with appropriate ammo and rifle. They did not have 22 ARC in about May of this year.

I have 3 BCA barrels that shoot which is 100% of their barrels I have bought.

I’m running 6 arc and 22 arc as UL repeaters but have scopes that dial on them.

What upper are you using on the 6 arc? Solo? Bear creek side charger or bolt?

I am using the bear creek right side charge with their 6 ARC barrel. It’s their carrier that I cut off the back half and their 6.5 Grendel bolt.

If you go with an ARC I would follow @Thegman recommendation to remove the gas rings and rubber piece inside the extractor spring. Those two make a big different in the force required to both chamber and extract a case.

I also have a Warwick Tactical right side charge with a cut and sanded bear creek carrier and KAK ARC bolt that I have a BA 22 ARC barrel on. The Warwick is tighter that the BCA upper but both are smoother/looser than the solo upper
