6.5 Grendel complete upper assembly

[Koda]

Rifle tubes are for the A1-A2 type fixed stocks. Carbine tubes, the smaller diameter ones are Mil-Spec and should fit the majority of "mil spec" stocks,

I dont necessarily want a GI fixed rifle stock. Can i put a carbine buffer tube on a rifle length gas system?

I would go on Grendel Hunter and slide the cursor over to where it says :
6mm ARC Upper
Grendel's new faster, flatter little brother.

Yes you can..it has been done many times
. In fact, the US military has the Mk12 that frequently gets a collapsible carbine stock on them, though it's 18" barrel, it has the Rifle gas length.


The only possible thing is.. buffer weight. You might need to play with it to get the feel right, but that's why most Grendel shooters opt for adjustable gas blocks so they can fine tune the whole system.

Aero Precision makes one that is pretty nice.

I buy BCA uppers, side chargers, priced decent and no issues.

good to know.
although, this is a dedicated rifle. I was planning on putting the Luth MBA-1 full kit on it which comes with a rifle length buffer. I guess if theres a carbine stock I might like I have time to look around. I just know I would never plan on collapsing a carbine stock on a rifle with a 20in bbl.

super helpful and what I was looking for.

So far here's what I know. ....

not too much difference between 2 inches bbl length, but for hunting and handloading squeezing out more velocity helps extend terminal velocity. I cant remember but I think every inch gains about 25fps. I know I want at least a 20in but ive just never handled an AR over 18in. Not that my bolt elk rifle is a short rifle though...

My notes tell me to get an adjustable gas block and only the type II bolt/chamber.

I have plenty of CFE223 on hand and already 100 virgin starline cases, and a few standard magazines...


been leaning towards the GrendelHunter upper because its customizable and longer barrel but I worry they take additional time to assemble in light of HB2005 passing. I dont know when HB2005 goes into effect if passed and fear its when signed.

awesome! i prefer E-Lander or C products mags for the grendel. its too bad they dont use a 5.56 mag.

ASC I think once put out a 15+? rd straight mag that Bill Alexander told them not to, and they torpedoed the brand (ASC)'s reputation.. Alexander came up with the more aggressive curve geometry and that's where C-Products and I believe other reputable brands came from. But for 10rd, straight is just fine, in my experience.

I wonder if you can convert them if we can find just the blue follower?
All I have is a handful of AR stoner mags I bought on impulse after 114 passed (back before Midway stopped selling mags to Oregon). I have one 5rd mag for hunting but I cant remember what brand it was, ASC I think. Now that Im officially 90% into the build I will get back to buying more mags after I pay the bill on this new upper.

They won't work as reliably even if you swap followers.

OK, OK, I know this is covered somewhere, but where is the best place to buy Grendel mags? Ones that work. Is a Grendel mag really required? If not, which 5.56 mag works? How about metal mags from ASC?? Thans of your patience, and comments.

Check this thread out, consensus is that the 5-10rd straight mags works the most reliably.

 

[Mr Smith]

C products 6.5 Grendel or 7.62x39 mags stack and cycle reliability for 26+rds. But usually you're not going to want larger cap mags because ammo isn't cheap for Grendel. When ammo was cheaper pre-covid it was still around $1/rd for decent ammo. It's only gone up from there..

Lots of recommendations for Elander and C Products mags. I'll check those out when I buy more. I'll give up the idea of swapping followers in 556 mags....

I'll keep the 7.62 tip in mind if needed. I agree, im not getting this for mag dumps or self defense needs, this is a for fun only bucket list project to add to my hunting lineup. I will probably look for 5 and some 10rd mags mostly.


side note: Ordered on Wed, shipping label received this morning. Never ordered from Grendel Hunter before but thats a good sign... I think. Hopefully they assembled it right.

I run C-Products Duramags in 10 and 20rd sizes, and ASC 10rd size. Esstac Shorty KYWIs are the largest that fits the 20rd Duramags, too tall for the 10rd mags which is why I made the 4 cell Retro style pocket. 11 of the mags fits a standard 30cal can by the way.
Edit. I also made a 3 mag retroish belt/MOLLE pouch for the 20rd mags

Haven't gotten around to making a 2nd triple mag pouch yet

Thats really cool, if I get this rifle ready in time for deer season I should fit a spare 5rd mag pouch to my pack.

Hate these threads...been debating on doing a Grendel...but 6arc has me intrigued also...
Only real concern for me is grabbing some mags before I cant...

I think Grendel mags will fit both the 6.5 and the 6?

 

[CamoDeafie]

So what I'm saying is... get both

I did take a close look at the 6arc... decided to stay with the Grendel for the larger bullet but the 6arc is going to be another great MSR hunting caliber.
Definitely get some mags now while you still can.

 

[Unka-Boo]

I did a grendel a few years ago, but with a blem bbl that had chamber issues...ended up selling the ither parts off....now I want to do another

Been toying with the idea of 6x45 also, since it would just be a barrel swap, but the 6arc and 6.5 bring so much more....
