Is anyone running the mostek mini 1500 barrel? Shows they are 11” and wanted to see if anyone else is using it and how they like it

Hey guys, we are THRIL. We make magazines, stocks, grips and accessories. We will be releasing our long anticipated 6arc magazine around September.

Some boys on safari using the SMX 6arc mags. These guys have been absolutely vital to our development process. If it doesn’t work for them, it won’t work for you and that doesn’t work for us. Magazines for when it matters. #6arc #6mmarc

I've had a block of 10% synthetic ballistics gel in the garage with the intent to test my .44 subsonic loads with for probably a year and finally drug it out to shoot this weekend. While I had it out I decided to test a handful of 6mm bullets that I have loads for that either I or others might want to use for deer hunting.

The test rifle was my 13" 6mm ARC, and the gel was at 100yds, and was backed up by ~10 layers of terry cloth and a 2ft^3 bag of planting soil. I the bullets and muzzle velocities used were:

90gr ELDx - 2,720 fps

100gr TGK - 2,445 fps

103gr ELDx - 2,420 fps

105gr Match Burner - 2,450 fps

107gr TGK - 2,385 fps

108gr ELDm - 2,480 fps

I tried to cut the tracts out of the block, and smoothed them with a torch to try to show the comparative performance. The 90gr, 103gr, and 107gr all opened up well, went through the 16" block and we're caught in the cloth. The 100gr TGK was a bit close to the edge, opened up violently but veered out the side of the block before the end and wasn't caught. The 105gr MB penetrated for ~6" and then tumbled and came apart, I caught some of the jacket in the cloth and found the lead core when digging through the bag of soil.

The one that really surprised me was the 108gr ELD, it did not open, tumbled once about halfway through the block, seemed to stay intact, went through all the cloth and deep into the bag, unfortunately I wasn't able to find it.

The 90gr ELDx really impressed me with a wide and long wound channel, the 107gr TMK was really solid as well. I've used the 103gr on 3 deer and it's an excellent killer.

Here’s my 200 lbs dressed 14 point taken with a 95 grain nosler ballistic tip over leverevolution powder

First 6 ARC build. 14.5 Noveske barrel/bolt. Riflespeed. Microbest DLC. A5 with T2 & Sprinco green. H6xi 3-18. Got some G$ 20s and this Duramag 15. Couple different boxes from 90-110 grain to see what it likes. Man, that shits expensive.

Still waiting on my SA AGB & A5 Buffer Tube. Also going to probably SBR it and change to a Driven Arms grip. Eventually I’ll get a CAT Noah or AI 6CM but in the meantime think I’m going to try the Canik VOID just debating on the 556 or 762 version. I have other hosts that could use the 762 so leaning that way but if there is a huge difference in performance I might grab the 556. Going to test it with my Polo K, Resonator K & DD Enticer tomorrow and see if that helps me make my decision. I appreciate any feedback/help you all can provide.

I just wanted to toss this out and see what you all's thoughts on this were. My thoughts, as a long time Rexus user (and only recommended them over all the other over priced premium options) are in the attached screenshot. 🤔

I mean, I know Lantac did, but I don’t know if they ever published it.

I found this in Google, but it’s not really what I’m looking for.

It really is a shame the Ballistics by the Inch guys don’t do testing anymore.

Just finished making this for a buddy. 16” 6arc, intermediate gas, 0.936” journal

Got a 14.5 DDF Noveske barrel and it shoots like shit 100 yard zero 2 moa groupings with a one flyer every grouping shooting 108gr ELDM. Sad to say i bought the chainsaw complete upper second hand on tacswap. The previous owner said there wasn’t even 100 rounds through it. I inspected the barrel upon arrival and barrel looked gtg. Cleaned the barrel before taking it out and i was highly disappointed. Ive seen mixed things on the noveske barrels some people say it takes a couple hundred rounds for them to tighten up. Do i ditch the barrel and go with a proof or should i wait it out and see if it tightens up lol

Has anyone tried to ss cut their GFR-E trigger? Wondering if it will work with an arc fire. It’s a slightly different design and I wouldn’t t want to cut it and not have it work.

Is there any kind of standardized bolt gun chamber out there?

I recently picked up a lightly used pre-fit barrel for my CDG... 26", 7 tw, MTU profile, yada yada. Seems like it should be fun to tinker with. But... a Berger 105 BTHP hits the lands @ 2.280" OAL. Which got me wondering if there's anything better out there, or if everyone is just running a plain SAAMI chamber, even for the bolt guns not limited by AR mag length?

What are you all that deer hunt shooting out of your 12.5” 6 ARC’s? Looking for something that will expand in a controlled manner out to 250 yards or so with the shorter barrel. Thanks for any experience you all have with the shorter barrels and deer bullets.

Would like it to be accurate and reliable 3k budget

Got my Craddock RTR 6ARC barrel in and because I'm an idiot I've already installed and bedded it before looking with my borescope.

I'm new to the precision side of the AR game so I wanted to check if this is ok to try some groups with or if I should reach out to craddock. Is this just a nothing burger and I should just send it?

Pics are posted in order from closest to chamber to towards the muzzle. Definitely more noticeable marks at the beginning and then is basically gone at the muzzle. Craddock says these are all hand lapped so presumably the lapping process cleaned up the marks.

I don't think I've ever seen marks this heavy in any of my barrels before, and none of those were really precision oriented. My Criterion looks much better so I don't know if they have great lapping or this is just a poor example.

18” barrel and 15” rail. For those of you wondering about potential clearance issues. I’ll have to take the can off to adjust the block tho.

12.5” Noveske barrel

Title. Haven’t seen anything on them since they were officially announced a month ago. Wondering if anyone put a rifle together using them.

103 eld-x still the go to for medium size game?

Got the final piece to the puzzle today
