I have emailed and talked to the owner of grendelhunter.com. Guy seems like a straight shooter. He even went as far as putting some different forearms on his uppers to give me exact weights. Every time I emailed him I got a response within a few hours. They offer a %5 military discount. I am going to end up building my own upper so I won't be purchasing one of his but just wanted everyone to know that the company seems like a good place to do business.

My main concern was I will primarily be shooting factory ammo and by a few accounts the grendel 2 chambers are shooting the factory ammo pretty slow( don't know this just what I have read). They supposedly can be handloaded hotter than the sammi spec( don't know this just what I have read). Since I wanted the best velocity I could get with factory loads and still have a fairly light upper I went with a alexander arms 18" fluted barrel.

Whats the wait time on the AA 18" barrel?

Grendelhunter.com 16" complete upper, ordered Saturday, shipped Monday, arrived today. So fast I have to wait a month until my bday to open it. I might be able to sneak it our for a peak and do a quick video overview in the meantime. When I do I'll let you know and post a link to the video in a new thread.

Like I said I don't know how these will work out. But the owner is really on top of things. If you have a question he responds quickly, not surprised they shipped it out so quickly

The barrel from Satern/Liberty has a Grendel II chamber which shoots 6.5 Grendel ammunition. The throat of a Grendel II chamber is different than a SAAMI 6.5 Grendel chamber with compound throat and .300 neck. The Grendel II chamber uses a standard tapered throat with long free bore to accommodate long heavy bullets. The Satern/Liberty barrels generally are head spaced to use bolts with a .136 bolt face depth referred to as a Type 2 bolt by Black Whole Weaponry (BHW).

I have read many good reports on Maxim bolts and are used by several vendors.

There really isn't anything wrong with either the barrel or bolt however Satern released several out of spec barrels several years ago. After this fiasco Satern introduced the Grendel II chamber implying the problem was with the 6.5 Grendel chamber design. This did not set well with many consumers and a few forum members. As a consumer you have to decide if the difference in the chamber design is important. The problem barrels were the button rifled bargain brand (Liberty) and not the Satern high quality cut rifled barrels. Satern still offers the cut rifled barrels with the SAAMI 6.5 Grendel chamber. I think Satern released the Grendel II barrels because they can be manufactured quicker and cheaper than the SAAMI 6.5 Grendel chamber.

Just when I thought I knew a thing or 2 about the chamber...
Are the Grendelhunter.com uppers the type that Alexander Arms sells with the .136 bolt that is SAAMI spec? Or are they a type II non-SAAMI?

they are the .136 bolt. No saami specs on the bolt. But the standard for AA and really any saami spec chamber will be .136 bolt. But the chamber is not saami. Its the grendel 2 chamber which does away with the compound throat. Some reports say that with factory ammo the Grendel 2 chambers don't get nearly as much velocity. On the other hand many say that with the grendel 2 chamber and loading out further allowing more speed in handloads.

I thought i read that the Type II chamber is made up & its either SAAMI spec or its not, someone correct me IF im wrong.

I think they are saying its only a 6.5 grendel if its the saami chamber. Otherwise its some bastardized chamber.
Its not made up because there are quite a few people chambering firearms in it. It is the grendel chamber without a compound throat. Some say its no different. Some say its not as good, while others say its better. But the chamber exist and is being sold in pretty large quantities

Its kind of funny the 6.8 spc kind of went through the same thing. spc1 then spc2 now everyone uses spc2. Thankfully the 6.5 grendel and all the variants can safely fire 6.5 grendel ammo! Thats not the case with the 6.8 which is why everyone loads the 6.8 at spc1 levels.

[Downtownjbrown13]

I'm thinking about ordering one so please keep us updated how you like it.

[dgunnut]

I put a quick video together last night and posted it. I am going to start another thread titled specific to this Grendelhunter.com upper and post the link there.

That was a totally different series of events.

6.5 Grendel chamber was developed after well over $10k in different reamers were tested across hundreds of barrels. The final chamber design that went into production has always been sound, and passed SAAMI certification without a hitch.

The 6.8 SPC chamber that went to SAAMI from Remington had some major flaws in it that should have never made it through if you ask many who have followed it, whereas others have said that the chamber was fine, but since people wanted more muzzle velocity, they weren't happy. Compounded with some initial run of Kotonics chrome-lined barrels, and SSA Combat loads, and guns were kabooming like never had been seen before in the AR15.

There were several different reamer designs for the 6.8x43 before SAAMI, one for more speed, and one for accuracy known as the "Murray DMR".

This grumble II business is fueled by laziness and unwillingness to comply with SAAMI, in my perspective, which is typical even in 5.56 NATO, .223 Rem, and .308 reamers from the same source as grumble II. I've had wonderful barrels reamed with what was supposed to be a .223 Wylde reamer or gas gun .308 reamer that would blow primers with factory ammunition left and right. Those reamers came from the same tool maker who concocted the Grumble II.

Visited Grendelhunter.com site...nice job. Discovered they offer a military discount, so sent a note requesting info...
In my military history we transitioned from flint to percussion to...just kidding...
M1 in basic, (Sept 1959) Carbine in Ordinance and Signal Corps.. Berlin Germany (Feb 1961.- Sept 1962) started with carbine then one day a wall then one day every soldier got a brand new M14.
Somehow I need this 6.5 Grendel to kill some hogs, etc. Hand load at my place, shoot from porch 😃 Other shoot locations out to 200 yards.
Stay tuned...glad to find this forum and sort out decision.
