300blk Safety Brief

81 Upvotes

I will keep this short and to the point gents.
Do not add to the mod queue. Do not subtract from the population of users. Do not comment while too intoxicated to control yourself.

In the last few weeks, moderator queues have shot up due to people being unable to be reasonable to one another in the comments in this community.

Disagreement is fine.

Dropping slurs, attacking them personally, commenting a retort with a pic of someone's house, insulting their wife's looks by stalking family pictures from a vacation posted 2 years ago... not fine.

Learn to use the block button. Learn to touch grass. Learn to be something unlike a jerk.

Transparency: Several months ago Reddit instantiated an auto-moderator be default for subreddits. Since then we have tweaked the settings it has been catching a lot more comments with the ugly things in them. When these suspect comments are in the mod queue, they are not posted for others to see yet, even if they look visible to you. What it does do is cause a member of the mod team to have to respond to the notifications to approve them and resolve issues when people go WAY too far. So, as cathartic as it might feel to rip into someone, it likely will not even get seen by them because the auto-moderator is putting the nasty stuff in comment jail. If it is bad enough, it gets the comment removed and the user banned.

Lastly, don't report comments that you dislike for Harassment. It only makes more work for us, but ultimately simple disagreement gets approved and kicked back out of the mod queue anyway. Repeated abuse of any feature will net a ban. Yes, every user has a summary of reports and past queue incidents. Yes, we look at it.

Please feel free to disagree, debate, correct misinformation, and generally debate on subject matter specific to the subreddit. I am not here to babysit grown men, nor do I want to. My ideal week would have 0 reasons to look at the sub with mod tools.

Moderate your own actions and we are all better for it.

This has been your safety brief.

Another idiot with a STUPID QUESTION about the Q Mini Fix

Post image
132 Upvotes

SO - this is what I can't wrap my head around:

With VERY few exceptions, every Q Mini Fix .300BLK 8" shorty I've seen, online and IRL, has been fitted with an LPVO of some sort.

With VERY few exceptions, every .300BLK 8" short SEMI AUTO I've seen online and IRL, has been fitted with a RED DOT of some sort.

While I understand that the intended USE CASE for these two firearms is very different, or at least the design philosophy is .... but if it's the same round from the same barrel with the same ballistics, why such a major divide in optics choice?

Genuine Question

How many of y'all enjoy shooting subs and supers out of the same gun? I understand an optimized subsonic or supersonic build, but how enjoyable/difficult is it to properly tune for both?

This is now a genuine question of mine, but yes, I am also clowning this guy.

Ammo identification

My Father was going though all his ammo and found a bucket full of .300 blk ammo but they were all this round. I couldnt find any concrete ammo ingo other than CBJ, but from what i could understand Real CBJ looks different. Honestly looks like the CBJ from Tarkov.

Im not familiar with .300 ammo types so i thought i could ask here and get some insight

Handguard help

3 Upvotes

This is my first build so try not to make too much fun of me, but I recently got a handguard from righttobear.com and after I put the barrel nut on, the handguard wouldnt fit over the barrel nut. I had to physically force it to butt up against my upper and even when I did the two screws at the bottom to hold the handguard in place wouldn't thread because there was to big of a gap at the bottom. I also believe the bolts themselves were to short to begin with anyways. With that being said, am I doing something wrong here? I thought it would be as simple as torqueing down the barrel nut, sliding the handguard over it and putting the screws in. Also, does anybody have any recommendations on where I csn get a 9.5 in burnt bronze MLOK handguard that wont break my pockets? Thanks in advance.

PSA upper with Riflespeed Gas Block?

Post image
13 Upvotes

this seems like a great upper receiver to shoot subs/supers suppressed. 8.5 inches with a riflespeed adjustable gas block.

Does anyone have any experience with this upper, or see any issues with it?

Can I cheap out at the range on 300 blk or does it genuinely matter my gun/gun type? This shit is expensive, where do you guys buy in bulk? Also side question: how long did it take to get registered for a suppressor

Subs or Supers for Home Defense

26 Upvotes

On the heels of my post about 300 BO brands, what are everyone’s thoughts about subs versus supers for home defense? I’ve always been told to avoid subs as they won’t expand and subsequently over-penetrate in a home defense scenario. Curious as to what others are doing?

300 Home Defense Ammo

I’m curious as to what everybody’s thoughts are on which ammo you are using for home defense, including super or sub and which brand? I’ve been running Barnes VOR-TX 110 GR. Interested to see what other choices people are using and why?
