Modern Varmint in 6.5 Grendel MAY 11 UPDATE

ATRS Shaun said:
Nothing finalized, but a basic second upper (no bcg) for a modern hunter is 2k. The varmint in 6.5 Grendel however requires an extra bolt face, we're using the jp enhanced ones so the price may be slightly higher, but around that same area I would expect.

We can't seem to obtain just the Fortis barrel nuts... If someone has a secret stash let me know, but it's not the first time I've been asked either :-/ seemed strange to me that for a "switch" handguard they wouldn't sell us the hand guards or barrel nuts separately.

Strange indeed since they advertise them on there website

Great little cartridge that utilizes 5.56 bolts and magazines so a simple barrel swap is all that is required. I have an AR in this caliber and and feel it could be a good MV addition for deer.

Hmm, it would certainly seem like I got mixed up a bit there, my apologies. Perhaps it was in regards to ordering a handguard without barrel nut, I'll admit that discussion was about two and a half years ago. I'll mention this to the gentleman who takes care of the ordering. Thanks for the link

No problem at all.

Just an update to keep you in the loop as to how our progress is doing with alternate caliber options for our Modern Varmint rifle.
Many have asked for a larger than 223 caliber in our Modern Varmint rifles to be offered, so that they can be used for hunting of deer and such.

We have been testing our rifle in 6.5 Grendel and so far things are looking very promising. Please do not consider this update a "done deal" as we still want to embark on further testing before we offer up this option, but it looking very promising.

We will be employing the JP bolt assembly in these rifles/uppers, consequently the price will be a little higher on either the rifle or the upper due to the increased cost of the bolt assembly. We will have to revise pricing and once we have it established and will update the options list on our order form once we decide if we will offer this chambering. Only stainless steel barrels will be offered, but in 3 different contours.
We are working on sourcing mags specific for the 6.5 Grendel caliber.

Before we get a bunch of " I want XYZ caliber" I want to be clear, 6.8 SPC has been explored and discarded as has 7.62x39 and all wildcat chamberings for many reasons.
The ONLY cartridge we are currently looking into at this time is the 6.5 Grendel.

How about 450 bushmaster or Remington 30AR? They are not wildcat in the sense that factory ammo for both is I¦ stock at Canadian retailers and proprietary Stanag pattern magazines for either caliber are available.

And with a little work you can have either caliber working off the same bolt

If the rifle is setup correctly (at a minimum Mid length, preferred rifle length gas and super bolts) it is a fine cartridge, but it can have it share of problems if a reloaded is not careful. My post is not intended to rain on anybody's parade but to highlight it has its share of issues in an AR platform.

Super bolts.

I think any cartridge can have problems if a reloader isn't careful. This includes not just staying within published load data but also selecting an appropriate powder for a semi auto action.

Luckily with an 18.6+ inch barrel there would be no trouble using a rifle length gas system to smooth things out.

Are the breakages commonplace or are we looking at a couple instances that the internet has turned into a bigger deal than it needs to be?

On any cartridge conversion that requires a larger diameter boltface I'd like to see it done the way the CMMG built their Mutant in 7.62x39 with an oversized bolt and carrier and matching receiver and barrel extension. This would beef things up significantly and also make them even less similar to an AR. Unfortunately it also means a lot more work and time programming the CNC machine and making more parts in house which would increase the price.

And significantly more expensive to make everything absolutely unique, and removes alternative sources for parts, etc. We are using the JP enhanced bolts and I've yet to hear even a rumour of anyone having a failure with one.

My AR-10 build had a JP enhanced nickel boron coated bolt that had the extractor pin hole drilled incorrectly and I had to send it back. It was replaced immediately by JP with a non NiB bolt that performed perfectly. Luckily I had a DPMS bolt in the bin to use while I was waiting.
I brought this up in one of the discussions where Epoxy was bashing the MH because it has a DPMS BCG to point out that even the highest regarded companies can have the odd sub standard part make it through QC and get into the hands of it's customers.

The super bolts I have posted are matched with a custom barrel extension that also can be used with normal bolts. I have a barrel and bolt being delivered from ARP which I will post on this site to illustrate the extra material. The designed straight wall brass of the Grendel compared to the damaging taper of the 7.62 x39 is a plus when thin wall bolts are used, However there can be failure numbers greater then any 5.56.

Big news on the MV standard version this am, any news on how your testing went this weekend or are you guys still debriefing... :)
 
Bump! Any news on the 6.5 Grendel testing? Credit card waiting... If its a go, I'm hoping to use it for deer this fall - or coyotes in the winter at the latest!

Further testing this weekend delivered great results both in reliability and accuracy, so 6.5 Grendel IS now an option.
We should have pricing worked out later this week.
