Need help on 6.5 Grendel barrel

[ichigo]

Hi all,

I was able to finish my AR10 build few months back and was able to take it to the range a couple of times. I started zeroing the scope at 50 yards just to get it on paper and move it to 100 yards true zero. The rifle hold it's own and I still have a long way to go to became a decent at long range. Planning to go 200-300 yards next time I'm at the range. The only problem now is that the kids wants to shoot it also at 50-100 yards but the recoil is exponentially stronger compared to AR15. Not sure if there petite frame will be able to withstand the recoil, so I promise them that I'll build another one that has a lesser recoil that they can handle.

I decided to build a dedicated 6.5 grendel upper and use the AR15 lower. I would like to asked your openion if a 20" HBAR or a flutted version is better for a $30 price and about a pound (1 lb) difference in weight.


Thanks,

If recoil is going to be an issue, heavy + a good brake. Do you have a AR15 chambered in .223 they can shoot?

Lots of options for Grendel barrels. Have Lilja, JP, Satern, Bartlein, AA, from 18-24, fluted and not. Get best barrel you can afford, as the confidence of accuracy will go a long way with young shooters. Keep in mind too, that you’ll shoot a 123gr bullet 400fps slower than a CM, so recoil will be less in kind. And lighter bullets are always an option. 100gr Nosler BT not a bad hunting option for the right shot, and accurate in my experience. If most shooting from a bench or blind, the weight of a heavier barrel won’t be a big factor-offhand might be different depending on age/strength.
An obvious Grendel fan, you’re going to love it.

Is there any reason you don't want 5.56? A lot more ideal for your stated uses.

Weight is good if it is mostly a bench gun, bad if not. Get an aggressive break or better yet a suppressor for it. Tune the gas system with an adjustable gas block too.

Currently, we have a 5.56 carbine length that they like to take to the range. They can hit clay targets (4 inches diameter) at 25 yards using the iron sights. I tried to put a red dot last year but the scope is a little bit higher due to the fix carry handle. Our chin is resting on the stock instead of the cheek.

The kids wants to experience shooting with a scope, since I let them dry fire the AR10. I found a sale on a ballistic advantage 20" 6.5 grendel barrel that is a heavy and a flutted profile with a $30 price difference. I'il be putting a fix rifle buffer tube to manage the recoil on the grendel.

LOP will suck for the kiddos.
Sounds like a swap to a flattop receiver would be the optimal/quickest/cheapest route.

Just got a 6.5g at midway for 350$ complete upper with bcg.

Shooting sub moa with hornady sst 123 ammo.

Recoil is barely past a 5.56 so its nice.

You can get the ammo for about 1.25 a round if you shop.

That brings me to this question for you.
Kids eat ammo like it was candy, sure you don't want to stick with the 5.56?
Spend money on better scope.

Just a thought.

I’m with Tony on the rifle length buffer tube. Run most of mine with Mil 6 position tube and CTR with thicker recoil pad. Mess a bit with springs and buffer weight to tune-an adjustable gas block simplifying the process. The kids can grow into the gun, without changing anything but LOP.

CTR and ACS/ACSL accept a Sims Limbsaver recoil pad. Not a bad option for kids shooting Grendel. Throw a A5 tube and buffer system if you are convinced Grendel needs a rifle length tube.

The Grendel is a good round for small/petite (my GF and her two daughters have them) and youn'uns if and when they start to shoot at the longer ranges (up to 800).

As noted - ammo costs should be factored unless you reload or are independently wealthy.

American Gunner is probably your best bet if you can get the 200 ct ammo cans. Black can be had for $.83 delivered and has proved to be a good hunting round, almost on par with SST for medium and large game.

You might be better off with a 5.56 and milsurp ammo if they are staying under 200 yards.

I have a couple grendels and like them, but when both of my kids are ready to start shooting I am going to build them a .224 valkyrie. Recoil will be indistinguishable from 223 and it will have a rate of twist that will play nice with longer bullets if and when I ever get to play with it. Also you can find plinking ammo for under $10 a box and save the brass if you are the reloading type.

The price on this barrel has me thinking hard about starting that build now.

Bought this Upper, and this barrel in 24", built the barrel into another (all SR Stoner) Upper. Waiting for temps and wildfire hazards to drop before going out to play. Currently 3-digits every day.

Using Starline brass, Speer 90 TNT, Hornady 123 SST, both as ammo and handloads with Win 748; and just bought 129 SST's as well.
