3/13/2024 0 Comments 22 short barrel subsonicPolice rarely need a hot round like the 5.56 or the 6.8 that I believe the US military will eventually switch to. I too doubt any military would completely switch to 300 Blackout, however I could certainly see the police doing so. The average user will never push a rifle like a BCM to its breaking point, so anything beyond that is just paying for minor increases in efficiency. Although with modern ARs you really get diminishing returns once you get over roughly the $1,300 mark. If you’re dead set on a gas piston system then look at offerings from POF or LMT. However 300BLK is much easier to use for an AR, as it uses the same bolt and mags(for the most part) as a 5.56Īs for the HK416, while it is a sick rifle it is incredibly over priced for what it is and HK doesn’t even sell the version with the good barrels to civilians because they hate us. The main appeal of 300BLK is the ability to switch between super and subsonic ammo, most 7.62×39 loads actually outperform the supersonic 300BLK loads. 5.56 is a much more versatile and widely available cartridge. It’s too much of a niche cartridge still and it’s main benefit is for suppressor use. Highly doubt any military will move to 300 BLK over 5.56, maybe some specialized swat units, and I’ve heard of tier 1 guys using them in certain scenarios, but not regular mil. And below, is pictured my home range located in my bottom pasture. The upper is an AAC SBR 300 Blackout upper. And with the 300 Blackout, I use 20 round magazines for the subsonic ammo & use 30 round magazines for high velocity ammo. Since 300 Blackout ammo & 5.56 ammo is so similar, I use solid black magazines for my 5.56 and use the translucent (see thru) magazines for 300 Blackout. In the pics below, note the backup sights down and then up.įor this rifle, I use a Saker 7.62 suppressor with quick detatch. The Aimpoint will run for around 3 years on a single battery, but if the optic were to fail in a crisis, the backup sights pop up & you can see them thru the nonfunctional Aimpoint. I use an Aimpoint Pro red dot sight with backup iron sights that fold down when not in use. There is almost no kick, it is very quiet with the suppressor attached, and it is simple to aim. This rifle, as with any AR styled rifle, is exceptionally easy to shoot. By using ammo that stays below the speed of sound, you don’t get that loud crack… plus the ammo itself is a bit quieter. With high velocity ammo, you get a very loud crack as the bullet passes thru the sound barrier. I mostly shoot subsonic ammo as it is much quieter than high velocity ammo. At my age, I won’t shoot anything past 100 yards, so that is a non factor for me. The down side is that this ammo is not well suited for long range shooting. Not silent by any stretch… but quiet enough you don’t need hearing protection. And best of all, when using subsonic ammo with a suppressor, the gun is rather quiet. This ammo also burns all its powder completely when shot thru a short barrel. This gives it really good knock down power. What I like about it is that it shoots a much larger & heavier bullet than a standard 5.56 AR. Oh, by the way, you have to get a stamp for each suppressor too.ģ00 Blackout ammo is relatively new. But put a suppressor on a SBR & it just feels & looks natural to me. The added length & weight of a suppressor to a carbine length barrel is just excessive for me. I like to shoot SBRs because I also shoot with a suppressor. The approval form is called a stamp & it costs $200 to apply for one. To have such a barrel, I had to apply to the government, the ATF, to get checked out & approved. The barrel is 11.5 inches long, as opposed to a standard 16″ carbine barrel. So to begin with, it is a SBR… short barrel rifle. So what to do? How about head down to my home range & do some shootn’! Today I’m shooting my favorite rifle… my 300 Blackout. I’m home alone, as my wife stays with her 100 year old mom several days a week. It is Christmas Eve, the sun is out & the temp is 70 degrees.
