Every AR-15 Caliber Explained

[@georgesakellaropoulos8162]

For my first non 5.56 AR, I went with the Grendel. This was before the 6mm. ARC came out. I have no regrets.

[@sammyG14platoon]

I build out a straightpull upper here in nz for my AR in 6.5 Grendel, runs mint so I built another in 6ARC and I can’t get it to run at all, the joys of no gas assisted operation …

[@Swampytheroot]

I have both only because in 2020 Grendel disappeared. ARC was everywhere. I still prefer Grendel

[@georgesakellaropoulos8162]

@Swampytheroot I bought dies and a shell holder. Been set up to handload for decades.

[@greenwolf401]

My favorite is the 300 Blackout. It covers almost all needs with its selection of different rounds.

[@assassinworks5538]

i got 300 blackouts and 223. wyldes want 458 socom next

[@garyK.45ACP]

Great review. 👍 I would only clarify that the "straight wall cartridge case" restriction applies ONLY to hunting. And applies ONLY to hunting deer in most of those states. Many of those states will allow the use of bottleneck cartridge for hunting varmints or small game, but not for deer. It is a _hunting regulation,_ not a restriction on the _ownership_ of firearms chambered for bottleneck cartridges. Always check state hunting regulations before going out in the field.

[@Raftjumper07]

I didn’t see 6.8 SPC II mentioned. It works for me. 👍🇺🇸

[@alexmouton2204]

I was about to comment this. Superb round for hogs and deer within 200 yards.

[@MichaelBrown-yp1eq]

the 6.8mm is the new US Military round for their new weapons system. it replaces the old 5.56, and in some ways the 7.62mm rounds. wish they had that round when I was in the Military.

[@arten]

I use 6.5 Grendel, 5.56 NATO, and 300 BLK. Two lowers and three uppers. I get excellent accuracy and precision with all three, and they are all fun to shoot. Lots of fun, and lots of options.

[@peterreily1490]

Lol. Are you ok? It’s all dog shit quality. 5 times RMA and kept being sent back still broken. GPX. $500 piston upper. They discontinued it because it was too expensive for their normal customers and those of us that could afford it, it broke. BCA BETS you can’t afford more than a couple boxes at most to shoot a year. If you see KZbinrs with a “good one” it was cherry picked. Enter, Focus Tripp.

[@Maimkillburn69]

A fully loaded mag would cost more than the upper

[@BrianDeWayneHale]

This video is excellent. Thank you for producing it.

[@HarshmanHills]

i have 22lr and 7.62x39 pistol uppers and they are awesome. going to keep adding more. for the price and quality, they can not be beat

[@elchupagoats956]

I'm waiting on a 22 ARC upper

[@lordhellfire153]

My only complaint is the 7.62x39 calibers (6.5 Grendel, 6mm ARC, 22 ARC) all have problems with their extractors being so small. The SPC calibers (6.8, 22 Valkyrie, .338 Spectre) don't have that problem and allow for greater powder volume.

[@dmann1209]

Awesome presentation! I like the 556 , 308 and the 300AAC calibers.

[@chiefwiggum3517]

6.5 Grendel! Awesome Cartridge!💪

[@nicks2581]

350 Legend = thumper of the intermidiate cartridges. It is a great all purpose cartridge that was initially made for deer hunting.

[@brandontanis388]

Great Video. Thank you.

[@geremi140]

Wow, great video

[@jdblackwell2]

300HAMR is conspicuous in its absence.

[@scott2228]

I’d like to convert one of my ARs to 300HAMR but have held back due to only 1 source for ammo. But it’s an extremely impressive round in my opinion.

[@jdblackwell2]

@@scott2228 It's a GREAT round. I can't understand why BCA doesn't carry it. I'm getting out of it because reloading is a PITA.

[@mathiask7959]

I think you can use the same mag for Beowulf as 5.56, you’re just limited to 10 rounds though

[@TheHippieGunner]

Built a 450BM for deer hunting, was looking to “extend” the range of my lovely Ruger 44 Carbine. 200yds no problem with the 450BM

[@stefanl5183]

You forgot to mention the .410 upper you guys sell? I would like to see you release a short barreled version of the .410 upper with a rifled barrel. A rifled barrel should be legal on pistol lowers. It would be like an AR "judge". The rifled barrel would help accuracy with slugs and should spread the pattern with shot shells by spinning the shot cup.

[@matthewhopkins1652]

How about 375 socom

[@inthewoods3237]

The 3 I have are awesome! Still thinking about a .22lr, and maybe 350 legend? Be fun to carry for deer even though I hate gun season.

[@davekurz6036]

[@MichaelBrown-yp1eq]

I prefer the .308/7.62mm, .223/5.56mm, and the .338 Lapua Magnum on the AR-15 WITH 20-24" barrel.

[@jasonraulston3922]

Wish ya'll start making 6.8 SPC and 400 Legend

[@rotisseriebear5394]

The 6.8 SPC isn't going to do much different than 300 BO supers, but since my dad has a Ruger mini in 6.8, it would be cool to give him a matching upper, and let him play with that. I was surprised when I shot his Ruger with off the shelf ammo, and rang the steel at 325 yards with a 1-5x Leupold scope. He had it dialed in for his reloads, so after getting good groups at 100, and a little Kentucky windage, I walked it out to the 325. I think they were 110 gr. If BCA makes one, I will jump on it.

[@jasonraulston3922]

@@rotisseriebear5394 they are both great rounds 6.8 SPC has more powder capacity you get quite a bit more energy I shoot a 16 inch 300 Blackout for hunting... I like it but the 6.8 SPC and as far as the impact on wildlife the 6.8 is better IMO and it better ballistics out to 400 yards than the 6.5 Grendel...

[@jasonlumetta]

AR-15 9mm, 40cal and 10mm were not mentioned. I have a 9mm and 10mm upper as well as 5.56, 7.62x39, 22lr, 450 Bushmaster, 50 Beowulf, and lastly 300 Blackout (didn't keep it). All of these uppers, I put together and are working 100% of the time, with the same lower.

[@VincitOmniaVeritas7]

The .458 SOCOM has the advantage of using standard AR magazines, but it does require an upper with an enlarged ejection port (as do the .50 Beowulf and the 450 Bushmaster).

[@richardsqueeze]

True, but you can only cram 10 .458 socom in a 30rd 5.56 mag.🤣🤣🤣
