Who makes parts and what's good/avoid?









Looking at finally getting an SBR upper now that I realise I can get brass from Brownells with the right export permits

Im not all up on the Grendel.  Will it do as its made for SBRd?

And look for Alexander Arms.  Black Hole Weaponry may make barrels for it

Black Hole makes good .264 LBC  Barrels, which is slightly different throat than a Grendel.  You can use all the same ammo etc.   whatever bolt you get make sure its 9310 steel
3/16/2014 9:03:29 PM EDT
[#3]
As far as bolts are concerned you need a type 2 bolt  .136 deep counter bore

Lilja makes beautiful barrels. I think they are currently using maxis firearms bolts for head spacing on their barrels. Why grendel for sbr though? Imo 300 blk would be a much better choice for sbr.

Just 2 reasons from what I can see that a person might look to the 300blk over a Grendel SBR , 1 would be subs and 2 would be that brass is cheap and easy to get. The big reason I see not to is the that the Grendel SBR will Smoke the 300blk in supersonic useage

You want to get a SBR 6.5 Grendel?  Am I reading that correctly?

That is not the caliber to SBR.  Great round but is best for long range precision not SBR stuff.  6.8 works great from an SBR or go with 300 BO.

Not sure why anyone wouldn't. Bill Alexander himself has raved over his sub 11" grendel ringing gongs at 600 yards. This round works phenomenally well out of a shorter barrel.

Where do you get your information from?  Huh?

I'm not a Grendel expert but I've always heard the same thing...need 18"-20" barrel to really utilize the full potential of that round. I'm not sure I would go with a 6.5G over a a 6.8 SPC or 300BLK for a SBR, as it's intended purpose is CQB and short-range work. The 6.5G does not offer any advantage over the other 2 for that distance and purpose, IMO.

Grendel works amazingly well in SBR. 10.5" pushes 100gr Berger at 2500fps.

12.5" is a great barrel length too, as is 14.5".  A 10.5" will keep a 123gr SST within expansion threshold out to 260yds, with a 225yd Point Blank Range using 200yd zero.

You can also go subsonic with Grendel using 140gr, 156gr, and 160gr. No cutting brass, no fire-forming. You have more forgiving gas system characteristics because of a tighter bore than a 300 BLK, which basically doesn't work subsonic in extreme cold.

The Grendel has several advantages over the other two in SBR.

Keep in mind that you have case capacity, a very wide selection of bullets, and still have retained energy at distance, even from an SBR. You don't need 18" to get the full potential of the cartridge.

My 16" even with factory loads is supersonic out to 1318yds with the 123gr A-MAX at my altitude, and is still 1000yd supersonic at sea level.

There was a very effective push to pigeonhole the Grendel after it was introduced, as to keep turfs in order, but none of the statements were based on testing.

A lot of Grendel owners, myself included, put our heads down, believing these statements, then went to the range to do load development, and realized even short barreled Grendel's have way more capability than was being recognized.

I originally had plans to own a 20" or 22" Grendel. Those plans are gone, and my 22" .260 Remington doesn't get shot a lot anymore.

The difference between performance in my 22" .260 Rem and my 16" Grendel with the 123gr A-MAX from both guns is.....

Do what you want, but  I use my Grendel for ringing gongs at 400-600 yards and when I want to kill something at 0-300 yards I use a 6.8 from a 16 inch barrel.  I think of the Grendel as a wonderful high BC round for long range precision shooting.  I personally don't think of it as a SBR type gun.  When I shoot a high BC bullet such as the Grendel I am looking for the highest velocity that I can get.  But that's just my thoughts.  Great little round for sure.

From Bill Alexander

I regularly run one of the 10 1/2" guns out to 600 yards. With 123 Scenars it is easy to get hits on and bowl over LaRue targets that 5.56 will not move even with Mk262

Guess he could have, I pulled the quote from a post from AlexanderArms and someone had said that it was Bill posting

ETA: a google search shows Mr Fortier talking about

to demonstrate the Grendel’s accuracy I put my Alexander Arms 20-inch GDMR (on which I replaced the stock barrel with a fluted Satern match barrel with cut rifling and a 1:8.75 twist) and Mid-Length carbine (standard chrome-lined Government-weight barrel with a 1:7.5 inch twist) to work.

Engaging targets from three to 300 yards with the 16-inch gun is easy. It’s light, quick to the shoulder and handles well. Smacking 20×11-inch LaRues from 300 to 600 yards is fairly easy if you keep an eye on the conditions.

Interesting. I will have to look into this. I just built a 20" grendel and my next project was going to be an sbr.

I run a suppressed 12 inch SBR in 6.5G.  shoots great for me, with much more downrange killing power than 5.56 in a compact package.  I'm not sure where the notion that a SBR 6.5G is not practical or whatever, but I'm happy with mine.

What are you SBR guys running for ammo? The last 123gr amax I saw was over a buck a round, and I can't do that for a blaster.

an SBR grendel is about as good as it gets in an AR15 platform. Makes .300 look pants-on-head retarded. Just need to find some mags and a bolt, I think. I can have a custom barrel made.









Do the PRI 6.8 mags work with Grendel?? 10rounders. that long OAL might be useful

Which Pmags are you using in 6.5 Grendel?

20 round standard pmags

When I have tried PMAGs with just a few rounds, they FTFeed. All the actual Grendel mags I have work flawlessly, and have done so since 2009.
