Ultralight Ultralight Rifles

I have a 6 ARC side pull. Just cut the BCA bolt down tonight and dropped 4 oz like another member a few pages back.

I think the ARC is having trouble in Solo 300 uppers because they are a lot tighter and rougher to cycle. I can push the bear creek side charge bolt with my pinky to full lock up. Extraction is no issue but I did pull the gas rings and extractor spring rubber piece.

I also was able to run 22 ARC as a side pull. Going to sell that barrel and balance of 100 rounds I bought because I thought I could gain 150 yards terminal range over the 6 ARC but turns out not enough velocity so nearly identical range.

My solo 300 with Shaw portless is much tougher to cycle than either ARC. Extraction I don’t notice a difference other than the rougher cycling on 223.

This lines up with my experience blocking gas port and using rear charging handle on 6 arc.

Just never got around to trying the side charger.


Would be curious if the experience is the same through 100-200 rounds

Any news on the group(ish) buy(ish) on the 6x45 barrels?

I am working on profiles for 16 and 12.5” barrels.

I hope to make the order in the next two weeks and open the presale.

Impressive! What load were you shooting?

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

Coming together, need to tap the BCG for the bolt handle. And, I will mill down my upper when I get my mill running.

So a Kaw Valley handguard showed up and I don't like it as much as the sink drain pipe I had installed as a stopgap with a barrelnut i had layingaround. The plastic pipe is just a hair thinner which makes it easier to wrap my hand around it.
So with that mind are there any handguards a bit thinner? Or any downside to the plastic? It does flex but it's not touching the barrel.

On another note I had a bunch of friends over and the UL UL Rifle got another work out. Even the younger kids liked it. I think it will get carried around a lot this year.
