There are suppressor companies that do support shooting their suppressors on a 7.5" 5.56. Of course the longer barrels will still be more quiet, but it is doable with the right suppressor selection.





 

While not 7.5" I do have a LWRC PSD with the 8.5" barrel. Never a single issue and is my most used rifle. Everyone loves to shoot it. Its not intimidating to look at for most beginners. You can always talk someone small into trying it over a larger rifle.

While I've never thrown on a crazy powered scope to see what it would do I'm positive it would surprise many.

And if you pick any good ammo it surely has the potential to take down most any target if needed.

Love It.

I feel like people exaggerate the unreliability of 7.5 ar's. I often read that 7.5's will either take a lot to get to function properly or will be a constant project that never achieves satisfactory reliability. Maybe manufacturing capabilities weren't as good as they are today and caused 7.5's to get a bad reputation, but it seems like from the SBR forum and ar pistol forum that 7.5's are in fact reliable. I haven't seen a post in either forum from someone who has built one recently that has had any issues with their build. Buy decent parts and I don't see why you can't get a reliable rifle.

Your second point however can't be argued with, the 7.5 dumps energy like nobodies business. If all you want is a fun range toy then this is your set up, if you actually want to do anything like hunt or home defense maybe a 10.5 or 11.5 would be better suited to your needs.

It's like the old saying, opinions are like assholes, everyone's got one.  You surf the forums here long enough you learn that there are plenty of people that talk about things they have no real world experience with (they heard or saw it somewhere) or they tried something one time and then believe anything like it has to have the exact same results even though it's got different parts.  If you want to make fireballs, certain flash hiders/comps/etc designs that do that.  If you don't, then there are other flash hiders/comps/etc designs that reduce it.

Like he said if you want a fireball you can have one ....

I don't want a fireball, I just find it funny that on here the 7.5 gets such a bad rep for being unreliable and huge fireballs, and how bad the muzzle blast is, (i can say the muzzle blast is quite a bit more than a full size) and how its just a range toy that was all

That picture was more for captexas and yes the 7.5 gets a bad rap. I have one that I shoot in a match friends put together. It runs like a top and makes good hits out to a hundred yards. My wife and daughters shoot it well with no complaints. I helped a few guys sort out their uppers and they run great now.

My 7.5 has fallen into my "go to rifle" slot.

I would say I have 3 or 4 thousand rounds through it and cant remember ever having a malfunction. I hold just as good of groups with it as my 16" rifles at 100 yards and have shot it out to 300 with good success. For me, something about the size and setup just makes it easy to shoot, I can run it markedly faster than my 16" rifles. .  

The drawbacks are that you loose a lot of velocity, it would be hard to suppress and its crazy loud... double ear pro loud (I have a JM break on it for shooting 3 gun).

O' and a 7.5 with a 22 conversion kit and suppressor is about as fun as it gets without a giggle switch.

nice, yeah i have had 0 issues with mine, it has a non adjustable gas block and still runs like a champ, getting ready to order a silencer co saker k to use on it and my 16'', it is my pdw, los of velocity is not a deal breaker to me, to me its having a sub machine gun size with all the same parts and mags as my full size rifle, and even at 23-2500 fps, i bet it hurts, and if anything 556 usually travels in packs of 20-30

7.5 Voodoo Barrel, runs 100% with wolf even.

Surefire MB.

Do it.

Why stop at 7.5?!  Olympic Arms makes a great 6.5 upper.  No problems with mine and it shoots anything from greeen tip (with a huge fireball) to cheap wolf without a hicup!  Not gonna make a 1000 yd shot with it, but it's tiny, and shooting it is more fun that you should be allowed to have with your clothes on!
