How to turn a 17 round mag into an 11 rounder!I remember those and that was probably what Bill A (Alexander Arms) was recommending. Should be good mags, IMI.
The one on the far right is the 800 series and even though I was making them in 2007, a guy (Kramer) filed for and received a patent in 2015. He threatened to sue me if I made any more, no Kramer has never made a single bolt. I could have gone to court but at $500 an hour it wasn't worth it.Would the Titan be only for bolt action rifles? Do they make one for the AR-15 ?
EDIT -- Didn't see the variety of bolts until I opened my laptop, sorry. Question: Then which of the two on the right would be best for the 6 ARC? And what might the difference be between them? And thanks for offering this info up.
Interesting. Very reminiscent of Knight’s E3 bolt.The one on the far right is the 800 series and even though I was making them in 2007, a guy (Kramer) filed for and received a patent in 2015. He threatened to sue me if I made any more, no Kramer has never made a single bolt. I could have gone to court but at $500 an hour it wasn't worth it.
The 750XD second from right is .750 Dia so it could be made and not infringe on Kramer's fake patent. The Titan just has a little better tolerances and is plenty strong enough for Grendle and ARC sized cartridges limited to 55000 psi. I explained more in the PM. I retired in 2017 and no longer make any of those big bolts.
Stronger than your average bolt. The bolt on the far right is the 800 series was designed to allow shooting a 6BRX(308 diameter) in and AR15, it came first around 2007 there were also Grendel and 6.8 versions. The second from the right and second design is the 750XD also works with 308 sized, Grendel, 6.8 sized cartridges. third from the right is the Titan, I designed it for Grendel/7.62x39 sized cartridges, never made those for the 6.8. 2 bolts on the left are 5.56 and 6.8 I believe.

Was originally told that it was a 6.5 Grendel Type 2. That’s what a am using. I do not know what Barrett has put in the actual military ones.What is Barrett doing for their 6mm Arc bolt? I got a non-answer from them a while back.
Honestly do not remember where the mags came from. I know of no new mags for the cartridge. Doesn't mean there arent any. Some of the ones I have are 17rd Israeli made for 300 BO. That said they only fit 11 of the ARC. Pic to follow
The orange tape is how I separate calibers
Yeah, I bought a bolt, mags and ammo while I waited on my PR cf barrel to be made. Still occasionally buy ammo just bc I’m conditioned to! There just were not many mags being touted as for ARC. Everyone I have met that has one loves it.I have had great experience, so far, with the lancer (white follower) and with the AR Stoner. Midway USA advertises the AR Stoner as 6 ARC, 15 round magazines. There are other capacities too.

I'm still around but I shut off all of the CNCs in 2017. The barrels are still being made but managed by someone else.Is this the same Constructor that was on 6.8 forums and sold some amazing barrels?
I made a few hundred TAC6 barrels and I still have a few of my own personal. It feeds well especially out of the LWRC SIX8 platform using Pmags. Maybe after I get rid of a million pounds of burden I can get back to doing what I really like to do.I like how the 6ARC performs after the trigger pull but thats about it. I have an ADM lower/Aero upper semi-auto rifle which has decent luck with ASC magazines, it hates E-lander, and CPD. The magazines are in my opinion the 6ARC/6.5Grendel Achilles heel. Every thread has the same stories about how Brand-X Mag works flawlessly but only on Tuesday afternoon if you download it by half capacity or magic-Dremel it to get 50% +5rounds. I would rather someone came up with a cartridge that performs like the 6ARC but better fit the AR-15 magwell to allow for more reliable magazine feeding - I don’t care how they do it or what parent case they base it on. I want to have the same braindead reliability the “put 556 in pmag and shoot it” people enjoy. If someone ever made that cartridge I’d barrel/bolt/magazine change and never look back.
@Constructor I remember reading a ton of your threads and seeing the stuff you were making. Unfortunately I was too late to the party and you’d already moved on.
Poke your head out from under that rock occasionally.For reloaders, find someone who shoots 6 ARC and doesn't reload. Make a deal with him/her to pick up his brass and buy it from him. Troll the line at the range to see if you can spot someone. Or you can just go buy it.
Those are E-Lander and the quality on them varies from great to utter crap.I remember those and that was probably what Bill A (Alexander Arms) was recommending. Should be good mags, IMI.

Where can I get one of these?The Grendel with a .136 recess is weaker than the bolt with the .124 recess 7-8% but still weaker, any engineer can explain that in about 30 seconds. The bolts below are the Titan, quite a bit stronger than the type 1 or 2.

Thanks for sharingPoke your head out from under that rock occasionally.
If the 6 man bun ammo or brass were available they would not be on my shit list. DUH
The only thing left on ARP website is a box of 40-some 7.62x39 barrels + extensions for $2K . The bolt face depth on x39 is incorrect for factory 6mm ARC though.Where can I get one of these?
I’m about to tear apart a KAC barrel for the extension and open up a SR-15e3 bolt to try to run higher pressures.
You are right, I tried Grendel cartridges in the LWRC mags when they first came out and found that they bulged to the point the mag would not fit in the magwel and told the guys on the Grendel forum they would not work. Of course a year or 2 later some guy with big fat thumbs said they would fit...they wont. Sure you can cram them in there but they will not feed correctly.You mentioning the TAC6A and SIX8 receivers brings back some memories.
There was a 6.5Grendel forum thread I stumbled into where people were saying the SIX8 Pmags worked at full capacity for 6.5Grendel. I put together a rifle based on the New Frontier Armory C-6.8 receiver set which is SIX8 Pmag compatible using a 6.5 Grendel barrel. Then I learned the internet lies; didn’t work at all much less at full capacity. I looked around trying to figure out what else I could do with a C-6.8 receiver set and 6.8Pmags, thats when I first came across your posts and the TAC6. Ultimately ended up giving away the receiver set to family who wanted to put together a 224 Valkyrie.
Actually its 40something Titan barrel extensions and Titan bolts at about $100 a set so $4000.The only thing left on ARP website is a box of 40-some 7.62x39 barrels + extensions for $2K . The bolt face depth on x39 is incorrect for factory 6mm ARC though.
Meant bolts instead of barrels! My mistake on the dollar figure and as far as x39 I only meant that the Titan bolts are listed as 0.124” recess on the page.Actually its 40something Titan barrel extensions and Titan bolts at about $100 a set so $4000.
for a gunsmith that wants to make a batch of barrels, I don't sell those to the public.
Not having feed problems with 6.5g mostly 123g bullets.
Mostly run 10 round mags target shooting and no problems at all.
AR-STONER Mag AR-15 6.5 Grendel, 6mm ARC, 22 ARC 5-Round Straight Body
The new and improved AR-STONER™ magazine for the 6.5 Grendel features a stronger stainless steel body for longer service life than the typical...www.midwayusa.com
Agreed. I emailed lancer magpul and a couple others asking about a 6 arc mag for this reason.Seems like the reviews are similar to every other 6.5G mag out there. They work for 70-80% of the folks, and the other 20-30% have failures. E-Landers, ASC, Cprod, etc all seem to do the same thing with regards to working for some but not others. It's a real shame nobody has cracked the perfect mag code for rounds based off this case, as they're a phenomenal step up in BC compared to 5.56 and let more folks hunt with ARs in states where .243 or some other "not .22 diameter bullets" are the minimum required caliber for some game species.
I wonder if the mag/feeding issues are actually indicative of a wider tolerance margin when it comes to bolts, barrels, etc for 6.5G/6ARC and how they interact with the magwell/lower receiver. Just seems odd folks have had such a varied experience with different magazines, some even using uppers built by the same shop. For instance, my 6.5G upper is a Larue UU kit, assembled by them. The E-Lander 24rd mags wouldn't work for shit, but others with UU uppers sing their praises. Is something off in the magazine QC process which allows for a lack of consistency, or is it an issue derived from the lower they're put in or the upper they're trying to feed?
If 6ARC really is going to some folks in uniform, it would be interesting to see what magazines they are no shit using...
Interesting... so do what shield arms did to the g43x mags but for different reasons. Maybe the 6mm arc being another cartridge using that same size case will push someone to finally make a mag for the 6.5g/6mm arc. Get enough of us consumers asking for it, and a secret squirrel dod group, and we might get it.When you stack cartridges in a mag the top of the first cartridge should touch the bottom of the 3rd and the second should be to the side and between the 1st and third. if you look close from the rear you can see space between them top to bottom. The magwel of an AR15 is not wide enough to allow that stacking and the thickness of the mag. It has been like that since 2005 when I purchased my first 6.5CSS(Grendel). They either need to make a larger magwel like the did for the SIX8 or the guys making the mags need to make the ribs a little thinner. Not sure if the will decrease side strength and allow the mag to bulge but this has been going on for over 15 years, seems like some company would have figured it out before they sent them to the DOD. The dies to bend the mags cost 100K or that is the price everyone throws out.
Any word on how they worked? Saw them but they were like $60 each and looked very similar to every other metal mag out there so i didnt buy one. I also wasnt positive i wanted to jump on the 6arc bandwagon yet but now i have a barrel so need to figure something out mag wise.and then there's the 6ARC mags by G that Brownells had for a brief period before they sold out (quickly).
A lot of the Brownells mags are rebranded ASC mags.Any word on how they worked? Saw them but they were like $60 each and looked very similar to every other metal mag out there so i didnt buy one.

Yeah, same here. Ill probably order a few of the duramag 20rnders just for the convenience of the box of ammo per mag and they have as good of reviews as anything else out there atm that im aware of.If you know a G dealer, they’re orderable items but Geissele isn’t shipping them. I really wanted to know if they’re a 400% marked up ASC or Duramag product, but not with my own money.
Good question. Do you know why?Geez. This thread is depressing. How am I getting away with flawless feeding of 22 Grendel in 20rd Pmags?
How many rounds per mag?Geez. This thread is depressing. How am I getting away with flawless feeding of 22 Grendel in 20rd Pmags?
Thats cool, have you tried the 20rnd pmags?How many rounds per mag?
I use the 10 round Pmags as a 5 rounder for 6.5 Grendel and they work fine. I know the 30's distort and malfunction if you put enough rounds in (~12 iirc).
Ill have to try the 20rnd ones, i have quite a few of those if they work on my gun.Honestly, I don't remember how many rounds I was putting in them. Or the 30rd'rs. When I slapped the gun together I didn't even think about using Grendel mags. I just reached for any old AR mag and laid my hand on a 20rd PMAG. Did load development and shot a Team match with it. Put it away and a year later bought a JP VMOS BCG for it and when I broke the gun out to rezero with the new BCG it was the first time it occured to me that I should've been using Grendel mags and the PMAGs "shouldn'tve" worked. I throated the barrel out and re-did load development shooting PMAGs the whole time. That was about 6 months ago.
I'll break it out this weekend and shoot it. I'll see how many rounds I can get in there.
I'm wondering if the gas system / components and adjustments some people have just don't work well with any particular mag or any of them.Seems like the reviews are similar to every other 6.5G mag out there.

sounds just like those folks that say their PSA is almost as good as KAC. (i'm joking)Yeah, same here. Ill probably order a few of the duramag 20rnders just for the convenience of the box of ammo per mag and they have as good of reviews as anything else out there atm that im aware of.
Haha, yeah i wish there was a solid one i knew would work like p mags work for 556 but there doesnt seem to be.sounds just like those folks that say their PSA is almost as good as KAC. (i'm joking)
the gouging of the projectile jackets is probably being caused by the knife-sharp edges of the barrel-extension feed ramps. If you remove the barrel from the upper, you can do a pretty good job of de-burring and polishing those sharp edges so that the projectile gets a nice smooth ride up the feed ramp into the barrel feed cone.Just got some Brenton mags in. That 15th round doesn’t really like to be loaded and I think it’s tensioned too tightly to feed well. Aside from that, they are the only mags that don’t drop free from my Mega lower. Pmag, duramag, GI mag all drop. We'll see how they feed…in manual/test manipulation I see gouging all down the projectile jackets regardless of which mags I use.
