ATRS Modern hunter specs, pics and range reports

I wanted something more then just a 3 gill brake, I was looking for a comp/brake and liked the look of the lantac over the ATRS brake. Now when I went into ATRS I was shown how the ATRS brake is machined to put downward pressure, it's pretty cool and may of went with it but I already had the Lantac lined up.

Lantac works better. I own both on AR's.
 
6MT, what does your gun weight with scope mounted? Not trying to be negative, but do you get the same type of flyers when shooting other rifles?

That 6th group u shot was looking pretty good! :)
 
Flyers count. 4 shot groups don't.

Strange the primer issue seems to be a problem. After somebody brought it up, there has been two more saying it's happening. Might as well report it so they can issue a fix and catch the change on rifles in production.

Looks like it's still a good shooter. Just have to find the ammo it likes. Or start reloading.
 
6MT> Great of you to post a report with pics.

Ahole with "Flyers count. 4 shot groups don't."> Please post pics of your groups so we can criticize it. Remember we are NOT in the precision rifle forum, be nice.
 
Picked mine up this morning, but it's been pissing down all day, so all I've been able to do is fondle it, and stare lovingly at it. Will post some pics once I've had a chance to take it out.
 
My problem has been light primer strikes. Two different kinds of ammo. 4-5 shots then light strikes. Took out bcg and work bolt some, fired another few then light strikes again. Haven't tried again since disassembling bcg, cleaning all parts and lubing up wet, as I hear that's how they like to run.

I'm not that experienced in the gas systems so this is just a guess, but could light strikes and blown out primers both be the result of the bolt face not being seated tightly enough to the base of casing? One symptom is that firing pin doesn't reach as far as it needs to, and in other cases allows explosion of powder to try to exit rearward? If this were the case is this a head spacing issue? Again, just thinking of what makes sense to me not knowing the gas system that well.
 
Hmmm, that is odd?
I have only had mine out for a couple of quick range break in sessions, but it has been flawless in its first 220 rounds, and primer strikes and brass look perfect. Mine is in 6.5 Creedmoor as well, which is supposed to be much more finicky about ammo selection and brass damage then the .308 ARs in general. Mine sure isn't though.
 
I've run about 700 rounds through mine. Tried almost every 308 round I could find except for surplus crap. Never had any light strikes. I have probably had around 10-12 blown primers, all on hornady match ammo. Mostly nickel cases.
Very minor in my mind. None of my hand loads have spit a primer yet.

Fail to fire and blown primers puts new meaning to "Modern Hunter" that is not what I look for in a "Hunting" rifle. And yes this is a concern to me. As a novelty rifle that is not cool but for a hunting rifle ........
 
I have shot over 450 rounds and no light primers and no blown primers -- and no failure to fire and no failure to feed and no jams

The Hornady "Match" ammo is known for blowing primers, I wouldn't put too much concern into this until further testing.

THIS is an AMMO problem rather than a rifle problem.

EVERY rifle we build is test fired. We have shot many many thousands of rounds through the Modern Hunter rifles and have yet to experience a light strike or a primer blowing out. The ammo we use for test firing is either Federal American Eagle 150 gr FMJ or Fiocchi 150 gr FMJ for 308s and Hornady ammo for the 6.5 CM and 260, Remington was used for the 243s and 7mm08s.

Like all AR style rifles these run a free floating non sprung firing pin. The 4lb hammer spring is designed to lite up even the hard primers like the CCI 34 and 41 as used in MG ammo.
My suspicion is bad primers and hot loaded ammo. Something that is already well known to be an issue with some Federal and Hornady ammo.

If your go to hunting vehicle runs out of gas is that a vehicle design problem?
 
Hornady Superformance in 308 blows primers in most types of rifles. Blew a bunch in my savage 10. Claim 200 fps more then regular loaded ammo, probably something to do with being loaded to hot.

I don't see Superformance listed in the few having issues - Uncledrillers
ATRS - I own a lot of rifles and zero of my rifles blow primers or have light primer strikes with any factory ammo.
I have harvested a few animals with my truck but that has nothing at all to do with my rifle, but my primary hunting weapon is a rifle - if it fails to fire I will wrap it around a tree lol.
ATRS your product looks great by the way.
