6.5 Grendel vs 300 Blackout upper

[damon1272]

Large Tactical has a smoking deal on a whole rifle kit minus the lower. Complete upper, Ceracoted with but stock and their trigger for $891. You can get it in 6.5 Grendel 18" barrel. Find another premium gun maker for that price.

I personally base all my builds on the barrel. Saving $100-$200 on a barrel is a false economy, as the cost of the barrel is nothing compared to the $$$ spent on ammo you send through it. The barrel is the heart of the rifle, and its the absolute last thing to skimp out on.

If I were building an upper right now for 6.5 I would use a Liberty or BHW barrel, "standard" mil-spec upper, Fail Zero or similar BC, Alexander Arms bolt, and whatever HG suits your taste (I like the OdinWorks or Seekins lightweight ones myself) and then drop it on your lower.
Note that the Liberty Barrel comes with a headspaced bolt-

So I've decided to definitely get a complete 6.5 Grendel upper and maybe a 300 blackout upper. I have a 5.56 upper that I might reuse the bolt and bolt carrier on for my blackout upper. Just trying to decide which Grendel upper to get. PSA has a huge selection of 300 Blackout uppers on sale. So do a bunch of other people. The 6.5 Grendel upper is a little harder to find.

This place has some https://www.bearcreekarsenal.com/new...per-assemblies

Larue had them too, shipping as well already I believe

991 assembled

Sell the trigger polymer stuff maybe get 100 back?
Muzzle brake if don't want (make$50 back) and if you assembled yourself, save 200 of the $991
Not bad!

Anybody with a Grendel have trouble finding ammo? It doesn't seem nearly as common as the 300 Blackout.

Sportsmans Warehouse is the only store in the north bay I have found it. I stocked up heavy on it and I reload as well.

300BLK is a fun round for 250 yards and under. I have a 16" and 10.5" blk ("pistol") in 300 BLK, the 10.5 inch is a lot of fun shooting steel at 100 yards, as it burns its powder effectively in the first 9" of the barrel.

My Grendel is 18" and setup to shoot 400+ yards. Totally different uses.

Ask yourself a couple questions:

Cost an issue? (BLK alot cheaper, same mags and bolt as 223, can make cases out of 223 cases if you choose to reload...)

What do you want out of another upper? Longer distance? Grendel is your answer. Harder hitting projectile under 200 yards? BLK will do this affordably...

My borther is big into lead casting, so I get free lead 30 CAL projectiles, and with the low powder consumption in 300blk I can plink at the range for CHEAP.

Both are fun platforms, the Grendel probably has more real use (viable hunting option into the 300+ yards for deer, can target shoot up to and past 900 yards) but 300BLK is alot less invested to play with. You could assemble a barrel, and using one bolt, one mag shoot 223 or 300BLK.

In 5 years your going to end up with both anyways, so dont stress on your choice, you will get the inch for a new caliber down the road and when that happens you can get the one you chose not to get today......

Add in the cost of a good scope if you go 6.5

I'm coming around more and more to the Grendel option. Can anyone suggest a particular upper manufacturer? It would be mainly for longer range shooting and hunting.

I bought an 6.5 Grendel 18" upper, bolt, and mags from grendelhunter.com. Good reviews on the various grendel forums. He uses Satern Liberty barrels, and an interesting blend of components. The website says that the receiver is lapped, and the bolt is head-spaced to the barrel. Haven't seen it in person, and won't be able to test it for another 6 months or so because of an extended "business" trip, but the family says it's a good build.

I'm looking at the Grendelhunter upper too. I also am liking the idea of picking up a blackout upper and just using my 5.56 bolt. Some of the PSA 300 BLK uppers are super affordable too

For short, both, for long, 6.5. I shot a bear up close, about 15 yards with the 300blk. The hole it made was so big that the air from it's lung coming out on both sides looked like the steam from a train. It was impressive.

I love my Grendel build, I have a precision build. Super fun and great distance/accuracy.

300 blk out is a great round too but pretty much the same as a 30/30 with less powder or 762x39. Without the use of a can it's pretty useless here imo. I guess you could always load your own and make some +p stuff that would drop a bear like stated above.

Otherwise if your desire is a great all around gun Grendel will blow the doors off anything else ballistically. Just need the cost to come down a bit or someone to start selling some midgrade ammo for mid-range prices like 5.56. I pay $1 Rd for match ammo and 20 cents for laquered steel case. There is a whole world of compromise in there.

Seems cheapo commie 7.62x39 is a harder hitting round than 300.

If you can hit with it. I was on a range one day with a buddy and his AR47 and some AK variant who thought his x39 was "as good as" the 300Blk and 6.5Grendel. He was always telling us how the x39 was "just like the Grendel but cheaper" and far superior to the 300Blk. I forget whose X39 upper he had, but the Ak variant was actually pretty nice for an AK.
Neither of his guns could regularly hit a large steel gong out at 200 yards that the 300 hit and the grendel destroyed. At least twice the craptastic commie ammo blew the bottom out of his mag in the AR.

Now if you handload brass case x39 and build a decent round, you might get better results, but I have no interest in going through the trouble. Especially with the extremely limited bullet selection.

300 BO as much as people hype DO NOT mirror 30-30 its slower. They compare to it as if it had a 20in barrel but the 300 BO burn pistol powders and reach maxim velocity at 16in going longer int he barrel does not ever get 30-30 performance its pure internet hype. You can;t run suppressed in Cali so no reason to go 300 BO. The Grendel has more energy from the muzzle out and has much cheaper ammo at 5 bucks a box. The cheap wolf steel case is good for plinking to 600 yards,. With quality ammo its good to 1000 yards. owe and X39 is not where even close to a Grendel as far as range and down range energy the Grendel smokes it completely.

30-30 out does the 7.62x39 too, but it the 300Blk and 30-30 are put in same class in the same way 300Sav, 308win and 30-06 are. The big plus the 300Blk has over 30-30 and 7.62x39 is you can use same bolt and magazines as 5.56 and 30-30 won't work in AR-15. It also uses less powder than both and has larger selection of bullets to choose from than the 7.62x39.
