SBR length with suppressor opinions

[O2HeN2]

Both barrels should easily be able to make hits out to 200.

That's a really big house!

11.5 and a halo...

That, except mine is a 10.3, and I'm still waiting on the stamp for the HALO

what is the advantage of having a QD suppressor?
This will be my second AR and I was thinking of saving a bit of cash with just going with a thread on such as the base line YHM.
Also, I was thinking about running a pretty long rail such as:

so it would have a very similar feel to my current 16" middy.
Of course if I ran that long of a rail with the can inside it, taking it on/off is out besides maintenance.

If you're just going to thread mount and leave it on, I say go 10.5" barrel and a Thunder Beast 223A.

Just keep in mind the shorter the barrel the higher the pressure going into the can. This usually causes erosion of the blast-baffle. However, there are cans designed to mitigate any erosion. Also, stabilizing the bullet is an issue with certain ammo. This causes the bullet to yaw as it exits and goes into the can = baffle-strike! I had a baffle strike in my can on a 10.5" barrel. This and seeing some erosion convinced me to use the can on my other 16" upper. Your results may vary.

what is the advantage of having a QD suppressor?
.

Unlike an SBR, a suppressor is the item with the serial number and can be moved between weapons. If you get a 30 cal suppressor that uses QD mounts, you can move that between mutilpe rifles in .308/300BLK/6.8/6.5/5,56 etc. For example, I have a 6.8 SPC SPEC II upper for hunting and a 5.56 upper for my standard AR/SHTF rifle. I bought a 7.62 YHM Phantom LT QD suppressor and can use it between the two by simply unscrewing it from the QD mount and putting it on the other. From all the reviews and YouTube videos I have seen, there appears to be a reasonably minor DB increase in using a larger can on a smaller caliber (usually 1-3 DB depending on the size/type of can) and a little increase in weight using a larger can but well worth it. Remember, you have to keep a copy of the stamped Form 4 with the suppressor when going between rifles but other than that, all good.

Other benefits to a QD are... that you can run a muzzle brake instead of a flash hinder to help slow baffle erosion and with a qd can it is more likely to not come loose during shooting. You rocksett the muzzle device on the rifle. The muzzle device will have some sort of ratcheting mechanism that will keep the can tight. As far as bullet stabilization goes you should always check to make sure the bullets are not key holing before you use your can on it. I have not had any stabilization issues with my 11in upper. Some 1:9 twist barrels seem to be closer to 1:8 where as some can be closer to 1:10. Just check your ammo in your gun before you shoot with the can and keep the can tight if you go with a thread on model and you shouldn't have a problem with baffle strikes. Another thing to remember is you are going to have this can for along time. Do it right, do it once, don't be cheep!

There is no "Quick Detach" suppressor. I guess you could try....but it's gonna leave a mark. I like the HALO because I can move it to any of my rifles with a peel washer on the brake. I didn't want to loose my BC 2.0 on my middy and I run a Vltor on my 11.5.
