Why NOT 300blk

OK, so I sucked it up and bought a pre ban lower to keep my options 100% open for my next build. Now while I am putting together the cash for the upper I am reading about the 300blk that I want to build.

Seems like a lot of people love it and a lot of people hate it. I am having trouble figuring out why people do not like it aside from the cost. So before I drop the coin a build myself a 300blk upper tell me why I should or shouldn’t.

Leaning towards a KISS carbine A1 upper with A2 aperture 16" with removable flash hider, and maybe a TA45 red triangle ACOG

Advantage - lower cost than other alternative cartridges.
Disadvantage - bullets function best within 300 yards - not optimum for long range.

Is this going to be your only AR, or one of many? It appears that you own others, so the question should be “WHY?” not “WHY NOT?” and should answer itself pretty readily. What requirement are your current ARs not meeting that the 300 would meet, and meet better than other “alternative cartridges”?

If you’re like most AR owners the goal is to have as many as possible in the safe, and the acquisition is the “fun”, in which case all the “why nots” in the world do not matter. It will meet those criteria:

  1. you will have more ARs
  2. you will get to “build” it

I haven’t heard of anyone who hates it… But I agree that you’d want to ask yourself WHY?.. not WHY NOT?

The people that I know who have 300 BLK’s, some have had problems, others have not. My 300 won’t cycle subsonics unsuppressed which is a slight disappointment but not a major calamity because my main intentions were to use supersonics the majority of the time anyway.

So rather than it being hate, I think the word is disappointing to some owners, being that their expectations are not being met. Once the bugs are worked out they’ll be happy campers.

What setup do you have which is producing issues for you? Which upper in particular?

I already have a 16" 5.56 carbine. Long range is not a concern, have a 24" 5.56 varmint ar and 308 rem700. I want this to be my primary go-to gun aside from my CCW, simple and lightweight for hunting, HD, etc. I already reload .223 and .308 so brass, primers, bullets are all on hand already. Am I asking too much for this caliber or am I missing anything. I don’t forsee ever needing this past 100-150yds.

The fans of the round are doing a good job of painting anyone who questions it’s utility, or why they actually want it, as a “hater”. Common debate technique of attempting to make your opponent look crazy when you run out of (or never stated with) and facts or answers to their questions. See also “ad hominem”.

That was an decision of the company who made your barrel - I know you know this, but for the benefit of new people, not a limitation of the cartridge.

Some people care about subsonic unsurpassed, most people do not and don’t see why if you had no suppressor would you choose to shoot more expensive and less effective ammo.

The flip side of the debate is - I may happen to have a subsonic round in my chamber and want it to work even if I have no can. Or I have permission to shoot low-velocity ammo at an indoor range that won’t normally allow centerfire rifle.

So it sounds like you just want it to want it, which is fine, but again what is your 16", or an SBR in 5.56, not doing or can’t do that the 300 can or will? How many of the projectiles you have on hand for .308 are usable in 300? How many projectiles that you buy for the 300 will be usable with the .308?

It seems that the most common answer to this is “well, duh, it has a bigger/heavier projectile” but few seem to have the ability to expound on what that really means, why it’s a good thing (or a necessary thing) for their application, or how that negates any downsides to it. Or why you’d want to limit yourself to the acceptable/useful range (which I think is right in line with the low end of what you mention) when other rounds can be more effectively employed at longer ranges.

The Barnes 300 BLK ammo does do well on intimidate barrier ballistic tests.

That is the short-long, I am attracted by bigger projectile and more energy. Sort of like 9mm vs 45acp.

Combine this with a few of the moderators here who appear to be part of the conspiracy… and it feels like this site’s credibility is going the way of ARFcom. :frowning:

Not sure why anyone would buy/build anything other than a SBR using 300BLK.

I’m still scratching my head at the marketing machine that has been done on a cartridge that fills such a narrow niche.

Just to add a couple of more +/-:

[ul]
[li]Bigger hole[/li][li]More energy than 5.56 to 300 yards.[/li][li]ALL components except barrel are the same as 5.56.[/li][li]Made for 16" or less barrel performance.[/li][li]It is now a SAAMI round.[/li][li]The Freedom Group, Inc. has bought into the round, and you have a large firearms manufacturing base ramping up production of 300 BLK products and ammunition.[/li][li]Subsonic energy and suppression better than MP5.[/li][/ul]

[ul]
[li]Currently limited product availability.[/li][li]Twist rates are in flux.[/li][li]Currently more expensive to build and shoot than 5.56.[/li][/ul]

Like someone else said, what are you going to do with it?

I think it’s an exciting development. It has a whole lot of potential for new and casual shooters as well as professionals. It also has the potential to really open up the SBR and suppressed markets to the average shooter.

I personally have the popcorn out for a little while longer until I see a better picture of where some of the negatives are going. I’m just a civvie who thinks 300 BLK is a decent improvement over 5.56 for self-defense and hopes it does well.

Tin foil brother, just gotta keep the haters civil. In regards to that a couple seem to have an ax to grind over it for various reasons I suspect.

I simply got it to hunt with, mainly for my daughter to get started and have a light adjustable carbine with mild recoil. For the range we currently have, it’s well within it’s power range to take the game, why use more?

I did the same with the 6.8, have one as well and my son uses it and I got stuck with the old school bolt gun.

Could we get along without either one, sure we could, but we enjoy it and it’s one more thing to do together.

and there you go. “haters” vs. “fanboys”
:sarcastic:

My interest in the 300BLK is for hunting.
Minimal change required to convert calibers.
I can then use essentially my GP AR for just about everything.

Dude, what?

Heck yes! :stuck_out_tongue:

George Noory was talking about it last night!

I think there’s only a few select true haters, I really haven’t seen the fanboy causing issues.

I do agree that a few may be getting it just to have/want it. I don’t see anything wrong with that either. I think we all could freely admit that we don’t “need” a lot of what we have.
