6arc CAT VB6 on 20” GFR, Tisha on LMT…and help

Big sister, little brother. Enjoying the look of a reflex can on a long gun. I’ll shoot the Maztek 15k for the first time this week out to 1000 yards, lucked into a great price from someone who was leaving the country. I know the scope on the 12.5” LMT looks stupid, but 6arc is stupid.

Here’s the help needed part. I’ve had a hell of a time trying to get information from SAW. I have a Tisha, 2x Shivs, and an Orev for a PRS gun on order direct from SAW since January and haven’t seen one and can’t get anyone to tell me what is going on. It’s getting painful to have dropped all that $ and keep getting nowhere. I’ve been in contact with “Matt” there, called, left messages, all the nice stuff. Anyone have a personal contact that can help me out please PM. I love their products but not so much right now.

Proof 20inch 6ARC. 10 of the first 11 rounds through it.

Factory 108 ELD-M. 2638fps (hopefully speeds up a bit with more rounds down the pipe.

Looking for a suppressor

What are you guys running for a suppressor on your 6 arc.
I got a 14.5 Noveske that has a pig pen muzzle device pin and welded. Anyone know if the Rhodie 6 will work on it? Or have experience with the Rhodie yet?
Also been eyeing the Cat Noah or CGS STI 6. Or better to go 30 cal for versatility?

I just want to know why

Saw this neat looking little foldy 6arc bolt gun. Wonder if I can find just the stock... 14k for the gun. I could understand around 4k. Am I out of touch?

OH I FORGOT you get 2 ~$9 cigars and Yeti flask..

Gas block and buffer system suggestions.

I am currently building an upper with an 18” rifle +1 Proof Research barrel and currently have a G Super Duty lower with the H3 buffer and braided spring.

Would this buffer and spring be optimal for cycling?

Also, which is best in your experiences, an adjustable gas block or would something like the Geissele Super Gas Block or SOLGW V2 work well?

Gas block advice sought

New to 6 ARC and just purchased an 18" Rifle+1 stainless Proof Barrel and a JP Enhanced Bolt. Anyone have any experience with this combination and have a recommendation for a gas block? I've heard some suggest non-adjustable for this combination, while others suggest adjustable, so I asked Proof and the rep who responded recommended the Superlative Arms Adjustable Steel Gas Block.

Grateful for any advice folks might have, given this is my first build. Thanks.

First day out with 6mm ARC

18" Shaw barrel really brought some new life into an old Aero SPR build . Sub MOA off just a bag at 100yds felt pretty good. 108gr ELDM really seemed like the money load @ .83 MOA for a 7 shot group. I liked the 105 gr Hornady Black BTHPs too. The 103 gr Hornady ELD-X it did not like at all, with some horrible vertical stringing. Big fan of 6ARC now.

New barrel

Just picked up a 14.5” proof carbon because it was only $800 at a local gun store. Anybody in the group have data on it? Thanks.

Range card data

Had the chance to shoot out to distance for the first time with my 6arc gasser. Build is a Noveske 12.5 DDF with a Deadair Lazarus 6. I was getting 2563 FPS with 108gr ELD-M which seemed pretty high but that’s the tried MV with data down range. Was about 80 degrees and shooting at 35m ASL. First round impacts at 1270 with a 4.3 mil wind hold. Super impressed to say the least.

Thoughts on a bipod?

Looking at possibly getting a bipod. I already have a tripod and bags that do pretty much anything I need but thinking about a bipod. Maybe something lightweight and stout that can take some abuse. Open to suggestions. Thanks in advance!

Evolution Weapon Systems w/6arc

I am just throwing this out there and am looking for feedback, opinions, and experience if you have attempted what I'm about to tell you. I am a big fan of running the Evolution Weapon System's bufferless bcg in a few builds (much improved design and function over Law Tactical ARIC. I have experience with both). I want to use it for a 13.7" 6mm arc pistol build. (if it pans out I will do the paperwork to sbr it). The system runs flawlessly with 5.56/.223 and functions well with 300blk after tuning the carrier with other springs. I think that it would run reliably with 6mm arc since they both operate under very similar chamber pressures for both cartridges (depending on the loads and charges). Any thoughts, opinions, or experiences that may save time in dealing with future unforeseen issues or variables creating issues are greatly appreciated. Thanks in advance and stay safe out there.

1200 Yards with a Henry Supreme in 6 ARC

I bought a converted Henry Supreme in 6 ARC and honestly didn’t expect to like it this much.

Shot it to 1200 yards this weekend. Wicked gun.

Originally I was debating between 5.56 and .300 Blackout, but after shooting the 6 ARC setup I kind of get why people are so obsessed with this cartridge now. Recoil is light, stays flatter than expected, and it absolutely smacks at distance. Anyone else shooting distance with these? 

What surprised me most is how well the lever platform worked with 6 ARC, some voodo magic. The unit is from LINE49 Rifle, they’re doing barrel conversion kits for the Henry Supreme platform and apparently a lot of guys are going multiple calibers instead of buying separate rifles.

They offer the barrel swap/install - from what I’ve heard the first changeover can be a bit of a btch if you haven’t done one before and I wasn’t interested in trying it.

Now I’m sitting here wondering if I still need a .300BLK… or if 6 ARC already ruined everything else for me. Has anyone shot the .300BLK suppressed, what are your thoughts?

Update on my BCA 6 ARC Bolt action upper

Well got my first upper about 5 weeks ago. Bolt would not close properly with a round in the chamber.
BCA did an RMA. Nee one arrived about 2 weeks ago and same issue. I tried a new Faxon bolt to see if that was the issue and was not. Used a GO Gauge to test and a live round.

Off to send upper number 2 back. If 3rd one fails then I am getting a refund or doing a charge back.

My 5.56 upper has been fantastic, this has been a sh!t show.

Anyone else get this in email today? Seems like a nice match for a 6ARC.

6 ARC case trimming

Looking to get a case trimmer pilot, however Lyman doesn’t have one for the cartridge. Will 6.5 grendal case trimmer work as a substitute?

LINE49 Rifles? Any experience out there?

Looking at some prebuilt 6 ARC Bolt gun options and this company popped up. They are a new company as of late 2025. I tried doing a search for reviews and videos which I cant find anything other than SHOT Show 2026 vids. I am always hesitant about new companies with newish designs. Their Supershort guns are based of the HOWA Mini action/ecosystem but more refined. I can get a 10% veteran discount which is nice. This is just one option and the other options are building one off ARC CDG or Zermatt Origin actions. Looking for 16" gun, nothing longer or shorter. I already have a 12.5" Noveske 6 ARC so don't want another gas gun.
